      Hi Thanks for reaching out. I donÔÇÖt have information about your project specifically, but given the error message the problem seems to be related to the meshing of your structure. I suggest paying attention to the smaller feature sizes in your design (perhaps a thin layer or a curved structure) and confirming whether the global mesh size specified in the solver will be able to resolve it. It might be a good idea to use localized mesh constraints (with smaller mesh size) for these areas to ensure they are meshed properly. This is also an efficient way of defining the mesh for the best accuracy/simulation-time trade off which will be important given that the simulation is 3D.
