Optimizating COMSOL model by using a solver implemented in MATLAB

Dear all:
I want to ask for your help regarding the problem I am dealing with right now.
I implemented a COMSOL PDE model with moving boundary and now I want to connect it with an optimization solver implemented in MATLAB in order to perform optimal control of the process, i.e. to pass a vector of control variables discretized in time from the MATLAB solver to COMSOL, to run it and to obtain certain output variables that will allow to calculate a given objective function which has to be minimised. Which is the best way to do it? Via exporting the COMSOL model as a Simulink block? Some experience using LiveLink? Other ideas?
I hope someone of you had the same problem in the past and could help me.
Thank you very much in advance!
Best regards
Luis T. Antelo

Hi
you ave also the optimising toolbox in COMSOL, and i its a single variable, what COMSOL is doing is least square minimising. The book of Zimmermann gives several examples

Good luck
