W62b92548

Conflicting local coordinate systems at symmetry boundary.

The symmetry plane is too close to a Non-Design Space which experiences LBCs which refer to another local coordinate system. The symmetry or the local coordinates might not be taken into consideration.

W2641b610

Symmetry causes all remaining DOF … to be fixed

The optimisation has reduced nearly all material which is not a fixation or part of the symmetry plane. All remaining elements are fixated. The applied force might be too small in comparison to the stress goal which ensures the reduction of almost all the material. Please reconsider your model set up.

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

Eb20f3415

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.
