Hi everybody!
I create simple 2D model in Comsol, then save it as Model M-file.
Open Comsol 4.2a with Matlab, in Matlab run this model. During execution Matlab said:
"
Error using feature
Input should be either a string or a scalar double
Error in model (line 67)
model.geom('geom1').feature('sq2').feature.comments('');
"
When i manualy delete line 67 in the M-File, model computing correctly.
What is this line ( model.geom('geom1').feature('sq2').feature.comments(''); )?
How to make sure that it didn't created?

Hi
I can give a guess that it is the property comments line of your square "2" tab, each node has a property window with creation date, authrt ... and comments line. Probably something has arrived therein, and the field is not properly closed.
It's not easy to tell exactly what to do, but I have noticed that COMSOl did (in 4.0 to 4.1 days) sometimes flag errors late if some entries where cleared, or not properly filled in
If it is something systematic, then report it to support

Good luck

Hi Grigory
This is a bug in Comsol.
You should manually remove the lines with empty comments from your m-file.
