Error in the coupled OpenFOAM and FEniCS

AymenAmiral1997 · November 28, 2023, 9:21am

I use an OPENFOAM V2206 and FENICS V 2019.1.0 in my research . ihave this error .
in fluid:

Hi @AymenAmiral1997,

this looks like an OpenFOAM simulation crash (probably for numerical / bad configuration) reasons, which however also complains that it stopped receiving messages from the FEniCS side.

Could you add more details and logs about this issue? I don’t think that I can help you with only this information.

AymenAmiral1997 · December 2, 2023, 10:09pm

Hi
I am figuring out what information to send you to help you understand my error.???
thank you

Makis · December 3, 2023, 9:11pm

some information about the case/scenario you are simulating
the complete OpenFOAM log (not only the last timestep)

The residual of the force seems to be a perfect zero before the simulation crashes, that’s strange and it should be the one leading to the floating point exception (probably a division by zero):

AymenAmiral1997 · December 6, 2023, 1:15pm

Hi sorry for this sudden inerruption
no i never reached this state

Makis · December 7, 2023, 9:58am

I think that you then need to look deeper into the results of every time step, check how each time step converges, check your parameters, etc. It’s a long process, which an external viewer cannot easily help with.

I would focus on the question: “why is the force eventually getting to absolute zero?”

AymenAmiral1997 · February 13, 2024, 12:28pm

Sorry for this time to reply , i dont undrstand this why i get a 0. look the same erreur .
the current number in the first is 0.01 in the end be 6.57
i think i have a probleme in the installation ?

@AymenAmiral1997 can you please format the error message correctly? You can use markdown code snippets for that. I cannot really read it like this.

What output do you get before this error?

hi @Makis
jai essaye de refaire la simulation sur un autre laptop jai refaire linstallation mais quand jai essaye de lancer la simulation sur fenics-solid jai cet erreur jai pas compris !!!

Hi @AymenAmiral1997,

This means that the preCICE shared library cannot be found by the linker at runtime.

Make sure that you have either

preCICE installed, or
in case of a custom installation directory: LD_LIBRARY_PATH must contain the path to the library.

hello i have the same probleme and i use the instruction to installed but when i do the command of the simulation i have this probleme .
if any one ca give the exact commands to install precice and fenics and openfoam to do the couoplage ; i try before two weeks but i have the same problem i dont undrstand !!!

You could try following the provisioning scripts for our demo VM:

github.com

precice/vm/blob/develop/provisioning/install-fenics.sh

#!/usr/bin/env bash
set -ex

# Install FEniCS from APT
sudo apt-get install -y software-properties-common
sudo add-apt-repository -y ppa:fenics-packages/fenics
sudo apt-get -y update
sudo apt-get -y install --no-install-recommends fenics

# Install the FEniCS-preCICE adapter from PIP
pip3 install --user fenicsprecice

Note that you need to install pyprecice and fenicsprecice for preCICE v2:

pip3 install --user pyprecice== v2.5.0.4
pip3 install --user fenicsprecice==1.4.0

Don’t forget to install FEniCS and preCICE v2 themselves.

If you have issues for so long, consider consulting your local admin / RSE.
