I remember Technical supports was telling me it is not possible to export the solutions for each loop. Are you trying to export your results at different time steps and update your solution based on the results from the previous time step?

@Aria Tsam Thank you so much for your information, sorry for late reply as I've just seen your message. I have read both documents but still can't solve my problem. I try to use function like setU() and createsolution() but I did not turn out the way I expected.

@Amin Rajabzadeh What you mentioned is exactly what I would like to do. I also contact the COMSOL support. They replied me that it is possible to do such a thing. However, they did not tell me exactly how doing it. They told me that they could not help me because when I start implementing the model on Matlab, it is already out of their scope. If you got some clue please let me know, I would be really appreciate.

Thank you

Let me double check something with you first. Do you need only to export the solutions at different time steps when the model converged completely or do you need to export the solutions at each time step, process them, and use them back in your model before solving the next time step?

Hi,

I only need to export the solution at each time step when model converged completely.

Thanks!
