java.lang.RuntimeException: Expression is not consistent with previous one

Hello,

I am new at comsol and at the moment am having trouble generating solver sequences from a study in a RF module of Comsol 4.0.
I have defined a simple geometry which can be varied by Parameters defined in the Global definitions.

When generating solver sequences it gives an error: "Expression is not consistent with previous one"

The "h" and "l" ar the height and width parameters, which are used for defining geometry, e.g., size of a rectangular object.
Has anyone encountered similar problem and found a solution for it?

Hi Edgards,
version 4.0 was released a is a long time ago and that particular version have known problems with the solver sequences. I advise you to upgrade to the current version of COMSOL (4.3b).

kind regards
