Hello to the Precice community, I want to develop a FSI code using Precice, the structural part would be solved by Calculix with its adapter and for the fluid the idea is to use a solver based on the Lattice Boltzmann Method (LBM) instead of the Navier Stokes equation. Using LBM should not be a pr…

Hi @Le_mot , that’s an interesting question. In general, you can omit the data mapping in preCICE and just apply the data exchange and acceleration. Checkout the following documentation page: Direct access to received meshes | preCICE - The Coupling Library . You would then need to perform both mappi…

Hi, thanks you for this very complete answer! Indeed, this section of the documentation page is very useful and close to my case. About the parallel cases, I’m not sure to understand the documentation. I if understand, I will be able to run simulation in serial and parallel (for the coupling) so Ca…

[image] Le_mot: I’m not sure to understand the documentation. I if understand, I will be able to run simulation in serial and parallel (for the coupling) so Calculix and my fluid solver will be able to run at the same time. Yes, you can run serial as well as parallel coupling schemes independ…

Ok I think that the architecture of my fluid solver allows me to deal with this problem thanks for your explanation ! Last question I hope, In the documentation of the Direct access to received meshes | preCICE - The Coupling Library it’s written : “This concept is required if you want to access r…

[image] Le_mot: If I understand, only the nodes of the solid in contact with the fluid are useful. So only the solid mesh at « the interface » has to be associated to precise. If we are in 2D it will be the contour line and in 3D the surface at the interface. Correct that’s always the case fo…
