How to correctly parameterize input dimensions for your FluxMotor-Hyperstudy optimization

I'm exporting my FluxMotor-model to a Hyperstudy connector, with the rotor's dimensions (i.e. the PM height, angle, width, outer rotor diameter etc.) as the input variables. Please see the attached snippet. However, in Hyperstudy a lot of the evaluations fail because the geometry is invalid.

Is there a way that I can parameterize these input variables so that they will always have a valid geometry? For instance, instead of giving magnet width, WM, as a variable, always make it fill the entire "hole". Or specify the rotor's outer diameter as a function of say "Outer diameter = T1 + TM + x", where "x" is then the input variable to be varied by the optimization and thus the rotor will always have an outer diameter where the magnets aren't protruding out of it?

I'm a novice to the Altair packages, so any help would be appreciated.
