no surf in comsol, is matlab live link a solution?

There's a solution u(x,t) in comsol, x and t are spatial and temporal coordinates. There's no

surf

function in comsol. Can matlab live link help plot a surf(x,t,u)?

Probably, but you would have to get the data out somehow (which is a question for a Comsol forum). After that, the solution shouldn't be that complicated.

I wonder if there's a command in live link Matlab to output solutions at certain x and t.

[Rik]

I don't know anything about live link. I would start with the documentation. Once it's a Matlab problem I can perhaps help you.

A different idea. If you execute "ver" in MATLAB and find you have "Partial Differential Equation Toolbox" installed, you might be able to move your complete workflow into MATLAB leveraging PDE Tbx rather than Comsol?

Is it that important to get a 3d-impression of the results ? Plots that are equivalent to "contourf" in MATLAB are available in COMSOL, and usually I found them more intuitive.

[feynman feynman]

@Andreas Goser Thanks for the suggestion. But does that mean I have to solve the whole physics in Partial Differential Equation Toolbox?

[feynman feynman]

@Torsten Thanks for the suggestion but as far as I know contourplots in comsol take spatial coordinates as arguments, not time?

If this is the case, (for me) the easiest way would be to write the results to file from COMSOL and use the data in MATLAB for plotting. Maybe you could use LiveLink, but I don't have experience with it.

[feynman feynman]

Right. Comsol is not quick responding to questions, that's why I reach out to matlab to see if anyone has experience.

[Andreas Goser]

My idea above comes from my experience in my PhD thesis, but this was 25y ago... At that time, the company Comsol developed the PDE Toolbox and I could use both, PDE Toolbox and what was then called Comsol Multiphysics if I recall it correctly. And from my perspective modeling/coding was identical.

[feynman feynman]

@Andreas Goser now quite different. comsol has a lot of built in modules
