Hi all,

I would like to specify different initial conditions in different domains for a heat transfer problem, but COMSOL only allows me to select all domains with one initial condition.

Is there anyone who can help me please?

Or you can specify piecewise initial conditions?

Hi,

The first (default) Initial conditions node has all domains as selection. Right-click on the physics interface and add more Initial conditions nodes when you need different selections.

Henrik

Thanks Henrik and Pu for your replies. I have figured it out already.
