Hi, i am following up with the shape optimization tutorial however am encountering the above error even with following step-by-step guide in the tutorials.
Please help to see what is the cause of error.
Error: SINGULARITY DETECTED AT GRID 2059 COMPONENT 3
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.
