COMSOL parametric scanning
 

I find that when I calculate something that geometric parameters should be changed using parametric scanning, it will show some error after calculating several parameters, not all of them.However, when I try to calculate the case it shows error before, not using scanning, it just works fine.What's more, it can calculate to the end of the parameter's list when the parameter is not about geometry:confused::confused: So I guess something goes wrong inside comsol.
Does anyone know its reason? Or maybe it is solved in version 5.6,I'm using 5.5
