Dynamic mesh simulations

[Nadun19]

I was wondering if CFDEMcoupling-PFM can handle dynamic mesh problems where the CFD mesh on OpenFOAM deforms. I am simulating a contracting stomach, therefore the CFD model has complex boundary deformation patterns.

I also had the same question. I found the tutorial case at 'cfdemSolverMultiphase/dambreak/CFD/constant/motionProperties' Does this file relate to dynamic mesh?

I was developing something along those lines in the past with the PUBLIC version. The first thing to check would be whether LIGGGHTS-PFM is able of mesh deformations.

Hi, hoehnp
Can you briefly describe your idea of solving the deformed mesh? I recently ran into the same problem where I needed to implement CFD-DEM-FEM coupling of deformable mesh in preCICE.

Hi @daxiangxiang,

basically it is required to transfer the deflections of every single node and move them in the STL based mesh of LIGGGHTS. Is your code somewhere available?
