Hi!
I'm currently developing a model using LiveLink for MATLAB, but I've run into some trouble. After I have solved my model, I need to extract the solution (the electric field) to compute the absorption in MATLAB. I then save the absorption to a txt file and import it back into COMSOL. All this works nice and and well, but when I then want to make a variable of this absorption, I need to update the solution. Is there a way to do so easily with LiveLink? I have looked in the User's guide, but I haven't found anything about this. Any ideas?
Best, Björn

Hi Bjorn,
It seems like not all commands are described in the documentation. However, one method I found to determine the Matlab commands I need is to first configure the Comsol GUI for a simple case, then save the Comsol file as a Matlab file. You can then see all the necessary commands that Matlab uses to configure Comsol.
In your case, to update sol1, you would need to do: model.sol('sol1').updateSolution;
Cheers,
Alex
