MultiRegion coupling in OpenFOAM using preCICE

Official adapters and tutorials
1

Dear All,
I had tried to couple scalarTransportFoam for fluid solver and laplacianFoam for solid solver by modifying flow-over-heated-plate tutorial. But the fluid solvers showed some error related to precice.xml file. Can anyone help me with this?

HI dibyendu,

You should put on the error trace here, and help others to understand your question better~

I have just started working with precice. I am trying to manipulate the existing test cases with different solvers. The test case is attached herewith.

I got the following error:

Courant Number mean: 0.0837143 max: 0.403668

HI dibyendu,

The problem seems happens in the precicedict, have you put modules (FSI); in your precicedict?

CHT module with solverType “basic” have been used for both fluid & solid solver. The test case is attached.

Simulation is running smoothly, and I’ve attached the case file for reference. Could someone assist me in adjusting the simulation time? Changing the end time in the controlDict files for both solid and fluid regions isn’t having any effect, and the simulation stops after 1 second.

HI, dibyendu
As far as I know, the end time of simulation is controlled by preCICE configure file.
