I received this error, when trying to resulve a model that seems (to me) pretty basic so I'm not sure what faces it is talking about, if anyone can guide me in the right direction it will extremly helpful.
The is the log of the error messege:
Scheduling job.
Job scheduled successfully.

Warning: REMOVING ISOLATED ELEMENT 36535 FROM OPTIMIZATION DESIGN REGION
Cause : An isolated element was detected within a TOPVAR design region and moved to the non-design
space of the model.
Action : If the element is connected to other elements in the TOPVAR design region, change the
property identification number or correct the mesh quality. If the element is
completely unconnected it should be removed.
Job has finished with errors. Receiving results.
Error: SINGULARITY DETECTED AT GRID 12363 COMPONENT 2
Cause : A singularity has been detected in the stiffness matrix during decomposition.
Action : Investigate the degree of freedom at which the singularity occurred for a lack of
stiffness. Also, check your model for a lack of constraint. If using shell elements,
either set the K6ROT model parameter to a value between 1.0 and 100.0, or set the
SHELLRNODE model parameter to ON. If this does not solve the problem or you are unable
to locate the source of the singularity, consider setting the SOLUTIONERROR model
parameter to ON. Note that solution accuracy may be degraded with this parameter set
to ON. Check the EPSILON value in the Model Results Output or Results Summary File.
Values greater than 0.001 indicate a possible loss of accuracy.
Error: Solver Error
Error: An error occurred while solving the model.
Can you share the model or some pics of the setup?

Don't ask me how but I was able to run it again it was OK, maybe different machine, maybe some changes to the surfaces of the model, maybe some changes to the settings that I'm not aware of...
