Running m-file from Comsol

Hello All,
This maybe a result of my low experience with Matlab. My end goal is to convert my Comsol MPH files to M-Files to be run on a cluster. I would be happy if I could first save a MPH file as an M-file and successfully run it in Matlab. This should be simple, but apparently I am doing something wrong.
Say I set up a simple RF scattering situation. I have my Comsol file all set, mesh generated, parameter sweep in place, boundary, and sub domains ready, etc. All I need to do in Comsol is press solve and things work beautifully. I was under the impression that I could save this file as an M-file, open it in Matlab and compute the solutions in the m-file.
Is this wrong? Do I have to change something in the M-file before it computes solutions.

Hi
have you tried to save your file as a ".m" file from the GUI ? (in V3.5a its still there).
But you can aslo, open matlab, linked to Comsol, call up COMSOL (or call Matlab from COMSOL if your install settings were OK) run the mph file, export the fem structure to matlab (CNTRL-F) and tweak the data from matlab, and if needed resend back to COMSOL for standard post-processing.
take a look at te mlinterface.pdf doc
Good luck
