Running *.class file from Eclipse without opening COMSOL

Please login with a confirmed email address before reporting spam

Ive attached code for a *.class file that runs a 2D heat problem and sets up everything to export a surface plot at the end but I do not know how to tell Eclipse to tell COMSOL to 'Click export' at the end. I have to open the *.class file with COMSOL, and click export. Any suggestions as to how to tell COMSOL to click 'export'?

Im starting the server before running in Eclipse (>COMSOL4.1>Client Server>COMSOL Multiphysics 4.1 Server). When I click 'run' in Eclipse, Im seeing that I connect but the plot does not appear on my desktop. At the end, it disconnects.

(To open file in COMSOL, remove lines 12 and 14)

Thanks
Alex

Hi

In order to have the Comsol Server show any graphics you have to start it with the -graphics option.

See the Installation and Operations Guide for more information.
