I have some basic previous exprience with Comsol but I just started using the Comsol Matlab Interface. I;ve been trying to import CT images into the program as my geometry. I looked at the Manual already but I still can't seem to get anything to work in the Interface mode. I tried to see if the proposed example would work (using the already loaded mri images in the matlab database), but the system just seems to crash. What parts should be written in a .m file and what parts should be written in the command line in matlab. Can anyone help me out? A for dummies version on how to import MRI or CT images would be great.

Hi

you have a difficult subject there, I have noticed many threads on importing "meshed" geometry on the forum. Some of the reasons are that COMSOL uses higher level geometrical "domains" to define the physics/application mode and not the individual mesh element as many other FEM programmes do.

There are a few third party softwares that transforms meshed geometry into a more compact representation, that is easier to use in COMSOL, check the main COSMOL site.

Try a search on the forum (and do no forget the main site KB)

Good luck
