Hello,

I am trying to set up the busbar example taken from the 'Introduction to LiveLink for MATLAB'-PDF.

I am using Ubuntu 12.04, MATLAB 2013a and COMSOL 4.3a. I am able to proceed until mphgeom() is called the first time to plot the geometry. It gives me the following error:

>> mphgeom(model,'geom1')
Error using mphpatch (line 124)
Java exception occurred:
Exception:

Error in /usr/local/comsol43a/mli/mphgeom.p>mphgeom (line 86)

Is there a fix for this?

Thank you!

Hi Damian,

try first using

mphgeom(model)

since you have just one geometry, I think that'll do it.

Tell me if that solves the problem.
