External Merge problem in Mechanica
We are trying to use Mechanica sensitivity analysis to vary the wall thickness of a casting component. The problem we have is the casting was created in two steps, a cast model, then a seperate external merge model to add the machining features. The shell thickness for the casting is defined in the first, cast model. We've not been able to have Mechanica change the parameter defining the shell in the cast model when we have the machined model active. It seems like Mechanica can change the parameter, but the thickness never actually regenerates.
So:
1) Is there a way to "cut and paste" or somehow get all the machining features into the base casting model so the external merge isn't needed? That way, we could just do the sensitivty study on the cast version, but it would have all the machining in it.
2) If that isn't possible, any ideas as to how to force Mechanica sensitivity to change the cast thickness even when the machined version is what is being analyzed?
All input is welcome and appreciated.
