Pro/Mechanica Optimisation

Hello again,

I'm trying to run an optimisation for a simple design of a water
storage tank. To do this I've created a solid of revolution, definied
by co-ordinates on a spline, with a few other constraints, and then
shelled it.

I would now like to set up the optimsation to vary the radii at
various heights of the tank, in order to optimise the volume per unit
mass of material. So far I can see methods in engineer (wildfire) to
determine the mass, but am having some trouble with:

1. Using these to derive parameters which could then be optimised.
2. Using any measure taken in engineer as a measure in mechanica.

Any tips or suggestions would be welcomed.

Thanks,

Gwilym

 

Are you using integrated Mechanica? if so all the parameters should be
available. If not (Independent Mechanica), you've got to create them.

You're near the point that I've wanted to get to... I keep asking when
do you need BMX? (Behavioral Modeling) Are you trying to have bounds on
stress and/or deflection? If not then I don't think you need Mechanica.
Rather you need BMX. Not that I've used it... just tried to get ready to.

You set up Design Variables in Mechanica: Dsgn Controls > Design
Params > Create > Dimension > Select and pick your varying dims to
use. When done, use Shape Review to verify all variable conditions
will in fact regenerate (this eliminates failures during the run).
Measures should also be created in Mech.

Mark
