Hallo,
ich bin ein Anfänger was Ansys angeht, daher habe ich ein paar Anfgangsschwierigkeiten. Ich hoffe ihr könnt mir vielleicht bei meinem Problem helfen.
Hier die Fehlermeldung aus dem Solver:

SPARSE MATRIX DIRECT SOLVER.

Memory allocated for solver = 46.330 MB
Memory required for in-core = 44.124 MB

Minimum memory required for out-of-core = 10.877 MB
*** NOTE *** CP = 3.947 TIME= 11:15:40
The Sparse Matrix solver is currently running in the in-core memory
mode. This memory mode uses the most amount of memory in order to
avoid using the hard drive as much as possible, which most often
results in the fastest solution time. This mode is recommended if
enough physical memory is present to accommodate all of the solver
data.

*** ERROR *** CP = 4.430 TIME= 11:15:41
A large negative pivot value ( -6.785683127E-13 ) has been encountered
in the global assembled matrix. This may be caused by a bad
temperature-dependent material property used in the model.
*** WARNING *** CP = 4.430 TIME= 11:15:41
An extremely large pivot ratio has been detected by the sparse solver.
This usually indicates a very ill-conditioned matrix or possibly
rigid-body motion. The solution may be inaccurate or even erroneous.
Please check your results carefully.

Ich hoffe das hilft.
Danke schonmal für eure Hilfe.
