Laminar flow inside imported mesh

Please login with a confirmed email address before reporting spam

Hi All,

I have been trying very hard over the last few days, but to no avail. I have a 3D CT scan data of a porous material, inside which I want to simulate air flow. I have the CT scan data in .tif format. I used many softwares to generate a mesh suitable for COMSOL. Currently, I am using Mimics (and 3-matic) to segment the solid and pores, create a volumetric mesh of the pores (in .mphtxt format), and then import that mesh into COMSOL. But when I start the simulations in COMSOL, the Multigrid Error comes always.

Is there any way to solve this? Any help will be greatly appreciated.

Cheers,
Sreeyuth.
