Gurus,
From time to time I try to run an optimisation study in Pro/M.
On this occasion it's fairly simple: minimise mass, stress limit
(max_stress_vm) 500 MPa, with two dimensions to vary. Previously it may
even have been just minimise stress with two dimensions.
Every time I try this I get the error:
"** Warning: Changing the parameters has produced invalid
model or geometry for the following parameter
values:"
and then it shows values which are only a very small change from the
model's current dimensions, and which regenerate fine if I put them back
into the solid model.
Then it spends ages
"Recovering from invalid parameter values by cutting
step size."
without really getting anywhere.
What am I doing wrong? Sensitivity studies work fine, but I feel I
should be able to give the problem to my computer and just let it go
away and find an answer!
Thanks,
Jonathan
