I'm a COMSOL 4.2a user. I need to solve 2D self-consistent Schrodinger and Poisson equation. Thus, I need to feed the potential values and the wavefunctions to the Schrodinger and Poisson equations as argument and solve iteratively.

The thing I need to know, how can I feed the updated the wavefunction and potential values as argument iteratively in my model? I have livelink with MATLAB and I intend to solve the problem inside a loop (i.e. Calling one models while passing the result of another as argument). I have solved the models with PDE solver but cant do it iteratively with LiveLink.

One more thing, is it possible to access the results directly from MATLAB and thus use them as variable ( though a class of course) from MATLAB for post-processing, like we get the solution matrix in MATLAB?

Thanks

Oh! I've found the solution myself at last!! The User Guide gives a clear idea about the very solution I was looking for. For those, who gonna face the same problem like me, I would like to refer them to have a look on the User Guide for LL Chapter 2.

Exporting variable issue is also discussed in the Used Guide. And FYI, a nice thread regarding exporting variable: damme7.zahooga.com/browser.php?indx=4878621&item=1

I hope, the thread is resolved.

Hi Mehedi.
I also work with Solving Self - Consistent Schrodinger and Poisson with MATLAB and COMSOL LiveLink.As you say ,the thing I need to know, how can I feed the updated the wavefunction and potential values as argument iteratively in my model?
Could you please tell me something details about the functions in the matlab and COMSOL LiveLInk to
feed the updated the wavefunction and potential values as argument.
Thank you!
