Parametric sweep and geometry change

a,b,theta_a and theta_b are global geometry parameters. theta_a = 2/a, and theta_b = 2/b. a,b,theta_a, and theta_b are all used in geometry creation.

I am running a parametric sweep for parameters a and b. When I do this the geometry that is created is not correct. The geometry created for each pair of a and b reflect the change in a and b but does not calculate a new theta_a and a new theta_b. Hence my geometry looks weird.

Any help will be greatly appreciated.

Hi

Parameters are static hence only evaluated at solver start, I would suggest to write those dependent equation directly in the geometry nodes.
Else they must be defined as global variables (that varies during solving), if the geoemtry accepts those (I havnt checked that)

Static Parameters can only be changed/reevaluated with the solver "parameter" node

Good luck
