Hi

I am working in windows xp os and with Comsol 3.5a with matlab R2008b

I am exporting model file form comsol to matlab as fem and is saved in fem file in workspace. when iam using postcrossplot in order to save it and use it for meshintegrate code for integration on a particular cross section in a domain.

but when iam using code postcrossplot in matlab command window as follows

pd = postcrossplot(fem,2,[0.015 0 0;0.015 0 0.03;0 0.015 0]','surfdata','T')

extracting temperature data from subdomian in a particular cross section and storing it in pd variable....

it gives error as

I think it is problem with java files and help me regarding this.

thanks for your precious help in advance.
