Hi
I am getting this error message:
*** ERROR *** SUPPRESSED MESSAGE CP = 236.516 TIME= 19:33:53
The inversion subroutine was supplied with a singular matrix.
*** ERROR *** SUPPRESSED MESSAGE CP = 236.516 TIME= 19:33:53
The inversion subroutine was supplied with a singular matrix.
What does this mean? Plus there is warning message as below:
linear tetrahedral elements have been used in regions with linear materials. This is not recommended
So what to do now?? Please help!
The first Error:
the message means that the solver tried to perform matrix inversion but couldn't do it because the system matrix was "singular", i.e. its Jacobian was zero. This can mean that there is some unconstrained part somewhere, or some zero-mass element somewhere; in other terms, either the stiffness matrix or the mass one has a zero value on the diagonal. perhaps you put some parts of your model unconstraint or did not define boundary conditions.
Hey Deepthi
Sorry not an answer.
were you able to resolve it? if yes what was the issue?
Am facing the same error for a modal analysis of a shaft supported on bearings.
Update: I re-meshed the model with different mesh control and i was able to solve it.
