Hi all - I've been working on some code in Comsol w/ Matlab that works fine on any machine I run it on - so long as I run it through the Comsol w/ Matlab GUI. No matter which machine I run it on, the program fails if I run Comsol w/ Matlab through a CLI. Specifically, the geominport() function fails to import my geom.mphbin file with the following error (gap is the name of my model m-file): Code (Text): >> gap ??? Java exception occurred: java.lang.NullPointerException at com.femlab.server.MlProgressDlg.runAndWait(Unknown Source) at com.femlab.server.FlRunnable.a(Unknown Source) at com.femlab.server.FlRunnable.smartRunner(Unknown Source) Error in ==> geomimport at 208 glr.jptr.smartRunner(report, 500); Error in ==> gap at 23 garr = geomimport('./geom.mphbin'); I am planning to submit this code as a job on a computer cluster where any kind of GUI interface will be out of the question. Has anyone using Comsol/Matlab encountered this problem before, and do you know any workarounds that will let me get my code running without a GUI? Thanks much!
