Hi,
The parametric sweep gave me just the last two solutions, any ideas to get all the solutions?

Thanks!

There are many things you could have done wrong. The thing that always kills me is using one parameter as the value of some other parameter I want to sweep. For example if I have a parameter Width that's defined 2*Length in Global Defs and I want to vary Width in a parametric sweep, I will only get one solution for the 2*Length value for Width. But if I set Width to be, say, 2[m], then the sweep will override that and give multiple solutions. The sweep overrides a constant value, but not a variable value. Personally I think that's a bug in COMSOL, but maybe it's a feature for some reason.

In any case, that's just one of many things that could be wrong with your sweep.
