I am trying to use preCICE to numerically investigate the flow dynamics of a density current interacting with a bottom-mounted elastic thin plate. I am thinking of whether InterFoam (the VOF multiphase OpenFOAM solver) can be coupled with CalculiX with the capacity of dynamic meshing. Would it be a …

Hello, I can confirm that the preCICE coupling interFoam or interIsoFoam with CalculiX works, but we had to use an adaption of the force estimation for OpenFOAM according maoxm’s fix in https://github.com/precice/openfoam-adapter/issues/127 for preCICE 2.0. Otherwise the forces have been by a facto…

Hi @jianzhou722 ! interFoam has already been used with the OpenFOAM adapter: FSI: OpenFOAM adapter with interFOAM fluid-fluid coupling in this fork There should be no fundamental problem and the approach would indeed be very similar to the standard FSI tutorial you mentioned. “Dynamic meshing” …

Thanks! Those resources are very helpful. I have a couple of questions: Are you referring to the interaction between the different phases in interFoam by saying “fluid-fluid coupling”? Or, if I understood correctly, did you mean “fluid-structure coupling” instead? I plan to use interFoam as the …

In Makis’ pull request it is changed to fileType::directory (emphasis on fileType instead of fileName). In case you actually have changed it to fileName::directory you could try to change it to fileType::directory and compile again.

Thank you sooo much @ajaust . :star_struck: After a day of errors, my brain was turned into mush. Couldn’t spot such simple thing. I was able to build the adapter and have the .so file, and will try and run the interFoam simulation and hopefully get back with results.

Hi, @uekerman I’d like to know whether overInterDyMFoam has been used with the OpenFOAM adapter. I want to carry out FSI with overInterDyMFoam and Calculix for complex elastic structure by using overset mesh to make the calculation stable. Thank you.

Hi @O_K , I don’t know if anyone has tried overInterDyMFoam, I do not remember of any such case. But interFoam seems to work (with some extensions to the adapter) for FSI, and I have also seen overset grids in coupled simulations in the past. So, this should worth a try. Note that at some point (ar…
