Hi Everyone…
Myself Lakshmanan Kasi pursuing PhD at Anna University Chennai, India. Working in the field of high speed aerodynamics and nanomaterials. I pursued my bachelor’s in Aeronautical and master’s in CAD CAM.
Interested to learn preCICE and to implement it in interdisciplinary approach.

Happy to engage with preCICE experts next week…

Hi all!

My name is David Barreiro, a PhD student at University of A Coruña (Spain) in collaboration with the von Karman Institute (Belgium). I studied both the bachelor and master in Industrial Engineering at the same university, where I had the opportunity to collaborate with the research group. My PhD project is focused on the CFD modeling of multiphase interactions.

I found preCICE some months ago looking for alternatives to couple OpenFOAM with external solver. At that time, I contacted Gerasimos to congratulate them for the excellent job and to get more info, but unfortunately I didn’t have time to go very deep on the details. I’m very happy to see that only a couple of months later, the community has grown a lot and much more information/content is available. In my case, I want to build the communication between a monophasic solver (let’s say pimpleFoam) and a python solver in a kind of FSI. For my application, I need to read the stresses at a boundary and, based on that, compute in python the displacements. I managed to do part of the job, but most of the times based on trial-error. From this workshop I want to learn more about the details of preCICE, specially the coupling techniques, mapping between solvers and how to correctly set the configuration file.

Looking forward to see you next week!



Hi everyone, thanks for this great initiative. Its great to learn what kind of multi-physics simulations people are doing around the world and how preCICE can tackle all those.

I completed my PhD from Penn State University in 2019 working on wall heat transfer modeling in IC engines. If I had known about preCICE back, I would have completed my PhD much faster for sure! I spent 2020 doing a post-doc in Texas A&M simulating flow past a cylinder with heat transfer and looking at wall modeling for such flows. Since Jan 2021, I am a post-doc at Oak Ridge National Lab working on multi-physics simulations of Fusion reactors (hopefully, I will get to see one of those for commercial power production in my life time). We are trying to develop a coupled solver (see attached figure) for neutronics (using MCNP and Shift), CFD (using OpenFOAM which is my expertise and HiMag) and structures (Diablo). This will enable us to test new Fusion design concepts and propose improved design suggestions.

I am very new to the preCICE platform, which looks quite promising. I am mainly looking forward to learn about:

  1. How to build adapters for commercial and in-house solvers so as to couple with other solvers via preCICE ?
  2. How to couple multiple solvers simulating multi-physics occurring at multi-scales ?
  3. How to parallelize the solution of multiple solvers some of which are surface coupled while others are volume coupled ?

Eagerly looking forward to the workshop.



Hi all,

My name is Jurgen Kersschot and I’m a PhD candidate at the KU Leuven, Belgium (Noise & Vibration Research Group – Mecha(tro)nic System Dynamics). My research topic is flow-induced vibrations in duct systems, or in other words, the interaction between the flow-acoustic field and the structural vibrations of the duct walls. The goal is to understand how this interaction affects the performance of noise mitigation solutions and to improve these solutions.

To study the interaction, I coupled an in-house aeroacoustics solver for the linearized Euler equations to a self-developed linear elasto-dynamics solver (taking mass and stiffness matrices from Simcenter 3D-NX Nastran). The coupling is managed by the preCICE library. As both solvers are written in C++, including the preCICE API was straightforward with the use of the step-by-step guide in the wiki.

I have been using preCICE since April 2019, first in my 2D test simulations and then for my 3D simulations (which have recently started giving decent results). I found preCICE during a literature study and I’m familiar with the explicit coupling between serial codes. I also build preCICE from source on the VSC-Flemish supercomputer ( and I run my 3D simulations there. During the workshop last year I got help from Benjamin Rodenberg to install the Matlab bindings on the VSC, but I was not able to use them yet in my research. I can only tell good things about preCICE.

During the hands-on user support sessions I would like to discuss how to couple the parallelized version of the aeroacoustics code (MPI) through preCICE.

Looking forward to next week!


Hello Everyone,

My name is Arnav Ajmani and working at IMVT, Universität Stuttgart as a research assistant. I learned about preCICE from one of my colleagues and quite new to preCICE. During the workshop, I look forward to learn more about this tool and also try to figure out how to exactly use it for my research project. My project is related to particle-laden fluid structure interaction.

I mainly want to understand and learn

  • development of an Adapter to couple a pair/number of solvers. For eg. CFDEM with Calculix

Looking forward to meet you all! :slightly_smiling_face:


Hi there,

my name is David Schneider and I’m recently joining the preCICE team in Stuttgart supervised by Benjamin.

I studied mechanical engineering at the University of Siegen for my bachelor and at TUM for my Master. I started already during my Bachelor thesis (at LSM Siegen) to work with preCICE and started afterwards as a preCICE HiWi in Munich.

I spent almost two and a half year as a preCICE-HiWi and worked on various things, mainly around preCICE: I have some contributions for our OpenFOAM adapter, developed our deal.II-adapter (my Master thesis was also entirely based on deal.II) and contributed many tutorials (mainly FSI). We also contributed a deal.II tutorial using preCICE :slight_smile: If you are more interested in the deal.II-related work: I will give a talk during the workshop…

Since I missed the workshop in the last year I’m looking forward to hear about your application cases of preCICE and get to know how you use preCICE and everything around it.

See you next week!



My name is Kin Wing Wong, I am a code developer from GRS gGmbh for the thermal-hydraulic code, ATHLET.

I studied nuclear engineering in Hong Kong and Switzerland for my bachelor’s and master’s degrees. I performed some researches on direct numerical simulation of molten salt bubble growth (for Molten Salt Fast Reactor) and the effect of bubble motions to heat transfer via sharp interface model during my time in Switzerland (Unfortunately, there is no coupling in such simulation :)). Now, I am working on heat transfer-related development in the system code developed in GRS.

Since I have no experience in coupling simulation, I would like to learn about some aspects of preCICE and basics of coupling from the workshop. Also, I would like to interact with some colleagues from the nuclear industry (as I can see from above), on all kinds of coupling problems with system code and CFD or FEA codes and learn from their experiences or ideas. I am mainly interested in the realization of the coupling from solid mechanics code to fluid solver or system code.



My name is Amin Totounferoush, I am a PhD candidate at the University of Stuttgart, institute for parallel and distributed systems. My research is mainly focused on developing and implementing HPC and Machine Learning methods with applications in coupled multi-physics simulations.

I am a preCICE developer. I have been working mainly on the inter-solver communication schemes in preCICE. You can hear my talk on communication initialization on Wednesday morning. Besides, I am a preCICE user. I used preCICE to establish a highly scalable solver for simulation of FSI problems. Recently, I have been working on coupling pure Neural Network solvers for performing multi-physics simulations.

I look forward to talking to you about your research and possible collaborations.


Hey there,

I am Oguz Ziya Koseomur and I am a Master’s degree student at the Technical University of Munich in the Computational Science and Engineering program, mostly playing with CFD, parallel programming and numerical methods.

My bachelor’s was mechanical engineering, mostly fooling around with fluid mechanics. Then I end up being a computer science enthusiast with great interest to develop quality and efficient software with some cool numerical methods. Other than this, I am mostly interested in CFD, especially combustion and turbulence modeling, and compressible flow (mostly beginner here).

It has been nearly 1 year since I began as a working student in preCICE. I am mostly in the part of main library development. If you ever used summation action, parallel Eigen-based RBF mapping, or built preCICE in macOS, yeap it was me in the background. In addition, I also do some comparisons in terms of coupling performance between monolithic solvers and preCICE based partitioned simulations.

In this workshop I would like to learn how people use preCICE, how it affected, and hopefully improved their interesting research and simulations.

See you in the workshop!


Hi all!

My name is Tijan Mede and I’m currently working as a researcher at the Institute of Metals and Technology (IMT) in Ljubljana, Slovenia. My background is in computational mechanics and I recently finished my PhD at University Grenoble-Alpes in France, where I was working on mechanics of fragile porous media and developed a microstructure-based DEM model for performing large strain simulations.

I am currently working on modelling thermal processes during metal-based selective laser melting. I have only recently become acquainted with preCICE, so please consider me as a complete beginner. I am however very interested in learning more, as it is what I have been looking for in order to perform conjugated heat transfer simulations. The general idea is coupling Code Aster and openFOAM in order to couple the conductive heat transfer during laser melting with the convective flows (Marangoni flows) that appear in the melt pool due to surface tension.

So the topic I would like to get hands-on experience with is mostly coupling Code Aster with openFOAM, but I’m very curious to learn all I can during this workshop.

Looking forward to meeting everybody!


Hey everyone!

My name is Julian Seuffert and I am currently a PhD candidate at the Institute of vehicle systems technology (FAST) at Karlsruhe Institute of Technology (KIT). My research focus is on the simulation of the manufacturing process of fiber reinforced sandwich components, which involves flow through porous media combined with the deformation of a soft foam material.

I am already familiar with preCICE and attended the last preCICE-workshop and the “Coupled 2019” conference. I use preCICE to couple OpenFOAM and CalculiX. If you have any questions on the OpenFOAM-adapter, I already used it a lot!

I am looking forward to the preCICE-workshop to learn about the newest developments and plans and also to see whats going on in the community.


Good morning,

I’m Menno Deij-van Rijswijk and I work at the Dutch Maritime Research Institute called MARIN. We develop our own viscous flow code called ReFRESCO, verified and validated for various maritime applications.

We are working on a project where overset grid calculations are used to couple different viscous flow solvers, and we have been looking at preCICE as a candidate to facilitate this coupling. Also, we hope to employ preCICE in other couplings we have.

I will be in and out of the workshop due to other engagements.


Good morning,

I’m Miriam Mehl, professor for ‘Simulation of Large Systems’(meaning Scientific Computing more or less) at the Department of computer science at the University of Stuttgart. I’ve been supervising already the first thesis on preCICE by Bernhard Gatzhammer (2010-2014) and the predecessor FSI*Ice by Markus Brenk. Coupled multi-physics and multi-scale simulations are currently one of my group’s main research focii, thanks to and of course using preCICE. We use preCICE for blood flow simulations (aorta and heart valves), porous-media free-flow scenarios, muscle-tendon coupling, coupling between simulations and visualization (to provide a black-box easy-to-use visualization for benchmarking), coupling between subsurface flow simulation and optimzation of geothermal energy infrastructure planing etc. in cooperation with partners in Auckland, Munich, Barcelona, South Africa, … and more to be added.

I’m looking forward to the preCICE workshop and wish you all an informative time with fruitful discussions.



Good morning everyone,

I am Denis Davydov. Since 2019 I work at Siemens Industry Software (software developer of STAR-CCM+). Prior to that I have been a post-doc at the University Erlangen-Nurnberg, working on various topics related to FEM, hp-FEM, Quasi-Newton methods, BFGS, matrix-free methods and other topics. During academia times I was heavily involved into the deal.II open source FEM code (principal developer). I am mostly interesting and curious about specific application cases of preCICE to FSI/CHT cases.



Good morning,

My name is Kyle Davis. I am a preCICE developer (and a little late creating my post here on Discourse :slight_smile: ). I am currently working on the quasi-Newton coupling schemes and looking at the robustness and speed of coupling, as well as data mapping and RBF mapping error estimation.

I started out using preCICE back in 2016 for the development of artificial heart valves, and eventually ended up joining the preCICE team in Stuttgart, Germany in 2019.

I would be happy to discuss the quasi-Newton coupling method, parameter selection and how they affect convergence coupling, as well as RBF mapping and parameter selection for mapping, so feel free to send me a message in the BBB chat later today!



Good morning,

My name is Cyrille Bonamy. I am a research engineer of a french research laboratory (LEGI - CNRS). I am often presented as an expert in software engineering and CFD, particularly the OpenFoam numerical framework.

My CFD activities are very diverse: sediment transport (sedfoam solver), aeroacoustics, or even FSI.

I do not use precice yet, but I am considering it for our openfoam coupling issues, starting with the FSI problematic.

I hope this workshop will give me the keys to start easily.



Hello everyone,

My name is Jochem van Heumen and I am a Master’s degree student Mechanical Engineering at the Eindhoven University of Technology. I recently started my master’s thesis on conjugate heat transfer from rarefied flows to a solid.

I have no experience using preCICE but I would like to learn about the possibilities to use it for my research. Therefore, I am looking forward to finding out how preCICE is currently being used and I see this workshop as a proper introduction to preCICE.



HI all,

My name is Fadi. I am a research Associate at Imperial College London.

I am working on a FSI project. I am thinking to use preCICE as a coupling library.
I am mostly interested in writing my own adapter since we are using an in-house code.




I am Eugen Gazenbiller and I am a PhD student at the Helmholtz-Center Geesthacht. My main topic is FEM simulations of corrosion processes in non-aqueous solvents. We also plan to use preCICE on a coupling problem between a phase field based fracture code and a Fenics corrosion code.

Looking forward to meeting you and learning the basics of preCICE and more!


Hello everyone,
My name is Ahmed Zoweil. I work as a Simulation Engineer. I am interested in using preCICE in CHT coupling of multi-phase flows in OpenFOAM.
