Hello colleagues,

i want so simulate the material removal which includes two big different time scales.
My approach is to simulate in the first study the fast physical phenomena (electrical pulse + vibration, timescale is about 0.02 s) and in the second study a slower physical process (removal, timescale about 10s)

In my first study i simulate an electrical pulse and an oszillating cathode and from that i can compute an average removal speed at the anode within the very short time (0.02s)

Then i start my second study with a deformed geometry (displacement = average speed*time) and after e.g. 10s i have a new geometry as a result of the electrochemical machining.

And now my problem:
How to implement an automatic loop/sequence in Comsol which solves the problem (Studiy1-->Study2-->Study1 with new geometry --> Study2 --> Study 1--> and so on) for a defined number of steps?
Or is it only possible to do it with using of Matlab?

I hope somebody of you have experience in such multiscale/ multitime problems and can hap me.

Thanks and greetings
Ingo
