Hello,
I saved my comsol model as a matlab file, to run it in matlab using liveLink but then I have this error.
Java exception occurred:

Hi
Please post your script so we can have a look.

Hi
The M-file you posted is quite long. The lines that doesn't work are for a component "b2" that is later deleted so I assume that these lines are not that important. You can try to delete the lines that refer to "b2" and see how it goes. I've tried - it doesn't really work smoothly.
The reason is that the script you export from Comsol by default includes all steps you have performed when working with the model. Hence it includes all the times you have solved the model.
Assuming that you just want to work with the final model and the final result there is a smarter way.
Before saving the model as an M-file select File->Compact History. The resulting file will be much shorter and should be easier to work with.
Do you really need to use the entire M-file? It can be nice to have the M-file in order to learn about the syntax for changing settings in a model, but as this post highlights - it is often much easier to work with a saved MPH-file and simply change the parts you wish to change when you simulate using Matlab.

Thank you so much it works for me now.
I want to export all the results from the model to Matlab that's why I thought to work with Matlab file.
Is there any method to export all the results from Comsol to Matlab
Best regards
