Hi all,
I am new to Comsol and I am trying to give a 3D laminar flow(spf) with time dependent studies in a cluster. I am using Comsol 5.2 and I am getting the following error.

The following feature has encountered a problem:
Problem setting up multigrid.
Unsupported geometric entity level.
Error in multiphysics compilation.


I have tried both Domain decomposition and Multigrid method for the Iterative methods and both methods are giving the same error. Any help would be really appreciated. Thanks in advance.
