Hi there,

I've read some relevant posts on how to use solver manager. But they seems to be mainly focused on one-way coupling. It's quite confusing for me to figure out how to do two-way coupling. I'm using COMSOL 3.5a and I don't have a Matlab socket.

In my model, I want to solve a time dependent problem. I have two geometries, one of them is PDE equation, the other is Moving mesh + Electrostatic. What I want to do is: at time step one, solve PDE equation, pass the solution to Moving mesh mode, then calculate the electrostatic mode after moving mesh, then pass the solution from electrostatic to PDE and solve it again and pass the solution to Moving mesh mode and so on and so on...

Does anybody have clue how to attack this problem, thanks a lot!

Hi
Even I am working on a similar problem with COMSOL 4.2, could some one post some example for this.

I don't think two-way coupling can be done only with solver manager, unless you can realize a loop within it. Script should work for your problem.

also having simmilar problems which I´m unable to solve. But I´m sure there is a solution. I've already seen models in COMSOL 3.5 working perfectly with boundary coupling variables but unfortunately there is no example which is realy helpful for my kind of problem in COMSOL v4.2
