importing a 3D gegmented image as a geometry

Hello everyone,

I am trying to import a 3D segmented image into the COMSOL as a geometry. Is it possible?
Actually, after testing a bunch of softwares and doing some tricky things I finally succeeded to generate a mesh for this structure and exported to COMSOL. A couple of modifications were done and finally I simulated fluid flow in this structure.
I beleive that if I can somehow export my structure to COMSOL as ageometry and let COMSOL to do the rest (meshing ,...) the life would be much more easier since I do not need to be worry about many isuuses which arises when you import a mesh generated outsude of COMSOL. I am still not sure if it is possible in COMSOL. Would you please help?

My structure is in .mat format(200*200*200 matrix of integer values 1 and 2 labeling pore and solid, respectively).

Any responce is highly appreciated.

Regards,

Hello,

I am trying to import a vessel geometry that was created from MRI data to do flow simulations in COMSOL. I tried to import the geometry in the STL format but I haven't gotten it to work (problems occur when creating the mesh) and I know that you had similar problems before.

Have you found a way to import geometry from MR or CT segmented data in COMSOL? I know that I can do it from Simpleware but I would like to find a free solution :-).

Thank you.

Best regards
Petter H

Hi Peter,

Finally I used Simpleware for meshing and since I was in rush I had to leave it there.

Good luck,
Saeid
