Hi,
I am interested in studying the heat transfer in a plate with a square hole.
I made the geometry of the plate and square hole and generated the mesh.
Also, the initial and boundary conditions are set for the simulations with MFiX-20.2. I got the following error when I tried to carry out the simulations with mfixsolver. I guess the error is related to the cut cell method. For your reference, the input files are attached. I appreciate your suggestions to get rid of that error.
