More verbosity from errors

Please login with a confirmed email address before reporting spam

Hello im pretty new in COMSOL and Im having problems settting up a model. Working with turbulent flow + reacting flow I have the error
Problem setting up multigrid
Analysis x has no mesh defined for geometry y
Error in multiphysics compilation
As you can imagine this has absolutely no meaning for me.
So anyone has a clue over the cause of the error. For the record the turbulence flow alone works perfectly.
Other thing. anyone knows if the message error can be turned to be "more explicit" im saying more than this short message????????

Hi

I agree it takes some time to get used to these, we have all the same issue, in your case your mesh is not complete, you have not meshed all entities (domains, boundaries ...) check your mesh and see if you should not add a final teth mesh node with the "remaining" selected, then COMSOL finishes off to mesh whatever is left unmeshed

Good luck

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.

Current Progress: 0 % - Form Union
Memory: 492/492 2020/2020
Open time: 43 s.
Running: Batch 1
Current Progress: 0 % - Reference 1

Current Progress: 0 % - Free Tetrahedral 1

Current Progress: 0 % - Smoothing transition to interior mesh

/******************/
/*****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.
