No solution steps defined ??
No solution steps defined ??
(OP)
Hello
When I try to solve an advanced simulation I get this message
"No solution steps defined. Solution steps required for given solution."
It's a simple NX Nastran, Structural simulation.
I've already defined the material, mesh and forces.
I've first tried with the option "iterative solver" enabled but also disabled.
Where can I find the setting I need to change to avoid this error?
regards

RE: No solution steps defined ??
This means that you have selected a Solution Type of say NONLINEAR STATIC Analysis (SOL106) where an interative & incremental loading scheme is used, then check your solution type seleected, if you select linear static (SOL101) then not any request of solution steps will be received.
Best regards,

I think the problem was that I was trying to use the volume as an objective and NX only allows to use it as a constraint.
Anyway the topology optimization sometimes doesn't produce any result nor give a clear error, and doesn't allow to use nonlinear methods, and the result is a STL file that cannot further used to perform analysis without first transform it with an external program. Needs some improvement.
