Hi all,
I am trying to compile with LiveLink for Matlab (Matlab version MATLAB_R2012a) a Comsol model (Comsol version COMSOL 4.3.0.151) that uses a physics interface which I created with the Physics Builder.

I have already exported the physics interface as a plugin and included it into the COMSOL installation. It works in Comsol. The problem is when I try to compile the *.m-file in Matlab. Errors are as follows:

Error using com.comsol.model.impl.PhysicsListImpl/create
Java exception occurred:
Exception:
    com.comsol.util.exceptions.FlException: Unknown physics interface
    (rethrown as com.comsol.util.exceptions.FatalReInitializeException)

Error in test_43 (line 20)
model.physics.create('TagName', 'PhysicsInterfaceName', 'GeometryName');

Does anyone have a similar problem?

Thank's in advance,

Comsol support has already solved my problem:

1. Export the plugin under the name com.comsol.myplugin.jar instead of just
myplugin.jar

2. Copy this plugin (as usual) into the plugins folder in your installation
directory

3. Add the line

com.comsol.myplugin.jar

to the file comsolpath.txt which you find in the 'bin' folder in your
installation directory. Make sure you do not overwrite any of the existing
lines.

Hello Savitri,
how do you compile your "Development Files"?
The PhysicsInterfaceBuilderUsersGuide tells:
"When you are satisfied with a collection of builder files, you can compile them into a builder archive."
"When your interface is finalized and you are ready to distribute it to others, you can compile all development files into a builder archive."

-> But it gives no details about how to do it.
comsolcompile integration.mphdev
leads to:
error: Class names, 'integration.mphdev', are only accepted if annotation proces
sing is explicitly requested
1 error

Thanks for any help
Matthias

Hello Matthias,
Are you creating your Physics interface with COMSOL Java API?
If you create the Physics Interface directly with COMSOL it´s direct to compile the archive. You have to right click the "Development Files" and click "Compile to archive folder".
I hope I have understood your question,
Savitri

Simple options are sometimes hard to find.
-> Maybe a relocation of the "Compile to Archive" Symbol - or a toolbar for the Modelbuilder could make things easier to find.

Thanks

Hello guys,

I have seen your post, and I ask you a question, as you might be able to help me.

I would like to compile matlab codes using that use Comsol 5.1 with LiveLink into executable files. I tried with the Matlab Compiler but without success. Do you have an idea how to operate, or a link to a website that describes the procedure ?


Thank you very very much,

Mat.
