This Error is only produced after another Error was encountered. The optimisation algorithm tried to continue despite the previous Error but could not continue. The optimisation fails with this Error although the primary Error is the reason for the terminated optimisation.

Projected memory requirement exceeds available memory - complexity … (detail …) is too high. Theoretical limit: complexity … (detail …), recommended: complexity … (detail …)

The chosen complexity value is too high to be calculated on this machine. A certain maximum complexity value is recommended. Have a look here.

boundary condition is missing elements

A Non-Design Space was removed and the applied boundary conditions are not considered

The Design Space has lost the connection to the force/constraint application point. The model is no longer complete and it doesn’t make sense to continue with the optimisation.

Make sure that the Keep Non Design function is activated. Increase the Complexity or increase the Safety Factor.
