Dear all,

in the bin/comsol.ini file I defined

MLROOT=/Applications/MATLAB_R2011b.app

The problem is that when clicking the app COMSOL with Matlab a problem appears.
checking the setlog I says something like


the path is not found: applications/matlab_R2011.app/bin/bin/matlab.

Then I check in matlab and actually I onlye have the path: applications/matlab_R2011.app/bin/matlab.

As you can see only one "bin" folder appears not 2. So I guess the solution is to fix the comsol.ini file and put one bin folder but I don't know how to do it.

any help

Hi
My suggestion, locate the ini file and edit it with notepad (previously make a copy for backup). I'm astonished there is no C:\ ... or something more absolute in your path

Good luck

Hello,

I fixed it... Actually I chose the wrong file... it was in the Mac64 folder and modified the files:

comsol.ini

comsolserver.ini

In this case there is no MLROOT, instead I used the typical -Dsc which appears in the manual. I copy and paste the path from the comsol manual since it was not there before.

I still keep the MLROOT=/Applications/MATLAB_R2011b.app in the other file which was somewhere else


PS: to clarify my mistake in Mac there is a folder COMSOL42 and the icon app COMSOL42, First I chose the icon with right click to get the contents and found the bin folder and the comsol.ini file (incorrect file since it has the MLROOT script)....but then I chose the folder COMSOL42, went to the bin folder and then to MAC64 folder and found


comsol.ini

comsolserver.ini


and works....however I have a new problem

Matlab opened, I upload my file and got an error, smthg like line 1209 X# : etc... The real mistake was that "[ ]" are not necessary in the script, so I deleted all the brackets as they were suggested by Matlab and fixed that problem....

Now when I run it, it runs really fast compared to before but I have the following mistake

Java exception occurred:
java.lang.IllegalStateException: Not active: CDOTransaction(1)
at
org.eclipse.net4j.util.lifecycle.LifecycleUtil.checkActive(LifecycleUtil.java:67)
at

etc

etc

Error in weak (line 10)
model = ModelUtil.create('Model');



BUT i don't know what is this error about..any help is appreciated

Hi Christian,
I have the same Problem.
It occurs when a model is loaded to the server and I try to export an other one with a different ModelName to the comsol server.

Did you solve your Problem? I also need to find one, because I want to handle multiple models within the same comsol-server.

model=mphload('PATH_&_MODEL.mph','Model');
model2=mphload('PATH_&_MODEL.mph.mph','Model2');

seems to work at least within matlab
