Hello everyone, I have a CFD code and a CSM code both based on OpenFOAM.I would like to couple them to solve a simple problem like the “cylinderFlap” which comes with preCICE and that is using OpenFOAM and deal.II. Basically to do FSI. As far as I know, I identified some of the steps to adapt the …

I have been able to run a simulation yestrday just by switching from an implicit to an explicit coupling ! So, this means that something is wrong while reading a checkpoint. I assume that in the explicit coupling the dimensions of Sf and magSf don’t change, right? I have not checked yet what is…

So, this means that something is wrong while reading a checkpoint. I assume that in the explicit coupling the dimensions of Sf and magSf don’t change, right? Indeed, no error is shown and the dimensions remain unchanged along the log file. Implicit coupling is especially important in strong…

I exported precice VTKs and imported the VTK groups in paraview but for now, it keeps loading and does not show anything. No matter if I want to use Glyphs or the Delaunay filter, the data does not even seem to load (the loading bar on the bottom right is showed empty - I tried with Paraview 5.4.1 …

This is very strange. Have you changed anything in the way the mesh vertices are defined? Do you write data on these meshes? No I have not changed such thing, that’s why I’m very surprised by the issue… However mesh motion is handled differently in the two solvers: In a Fluid timestep directory t…

I have simplified a bit the config file : <log> <sink filter="%Severity% > debug and %Rank% = 0" format="---[precice] %ColorizedSeverity% %Message%" enabled="true"/> </log> <solver-interface dimensions="3"> <data:vector name="Force"/> <data:vector name="Displacement"/> <mesh name="Fluid-Mes…

Hi @Makis , To be honest I left this issue to focus on something else. Actually, I reinstalled the whole preCICE machinery yesterday. I will start fresh with the newest precice (2.0.2). Two quick things: I chose to change my test case from the cylinder flap to the flap_perp one. Indeed, as I a…

[image] dashqua: I have no choice since the nonlinear_elasticity won’t compile. This looks like exactly this issue . It would be helpful to document your dependency versions there. But ingore my parenthesis, let’s keep this thread about coupling with your OpenFOAM solid solver. [image] das…

Hello @Makis , This thread had been up for many time so it can be easily confusing for the both of us ! You are right, let us focus on the coupling. I wanted to run a tutorial case with the brand new installation before going back to my OF-OF coupling code. The 34th post and those before are about…

Just as a side remark (I haven’t followed the whole discussion, but the preCICE bot mentioned): The nonlinear solver should compile now with the current develop branch of the dealii-adapter. In order to run successfully tutorials with the deal.II codes, your OpenFOAM adapter needs support Stress da…

@dashqua how is your current state? Are you observing that pointDisplacement is not overwritten or has there been any news?
