ressure / acceleration loads cannot be tied with RBE2/RBE3
RBE2 / RBE3 can only be used for forces or displacement constraints.

tool … is facing the wrong way with respect to symmetry planes. Make sure all tools draw towards the positive side of all symmetry planes
Hard symmetry is active and one draw direction is normal to the symmetry plane and redundant.

RBE3 tyings cannot support fixations
RBE3 elements do not support displacement constraint. This makes the FE matrix unsolvable.

Using RBE2 point masses with linear-static analyses is not supported yet
RBE2 isn’t supported for static load cases / events yet. It is supported for frequency load cases / events.

Please use nast20233(.exe) (or the matching executable for your installed nastran version) for frequency analysis
nast20233w.exe isn’t suitable for the frequency optimisation

failed to execute nastran sub process
For eigenfrequency optimisations MSC Nastran is called in the background. In this case Nastran cannot be executed.

Requested nastran operation but did not specify nastran service. Please set env variable 'EMENDATE_SERVICE_NASTRAN' to point to your nastran binary.
If you want to execute a frequency optimisation directly in the command line, you have to set a environment variable which points to the nast20233.exe
EMENDATE_SERVICE_NASTRAN | C:\Program Files\MSC.Software\MSC_Nastran\2023.2\bin\nast20232.exe |

Start candidate volume far exceeds design volume - check scaling.
One reason for a large difference between the volumes is the unit system. Make sure the start space geometry is in SI units and start the optimisation anew.

Insufficient complexity for maxThickness. Suggested minimum complexity is …
For a chosen max. Thickness value the Complexity needs to be high enough to represent the desired structure with enough voxel elements in the background. Please increase the Complexity value or the max. Thickness value.

Invalid RBE2 constellation - overlapping nodes
Several RBE2 elements cannot be applied on the same spot for the same Event. This makes the FE matrix unsolvable.
