WARNING: G3008
|
elemtype ELEMENT
id IS NON-POSITIVE DEFINITE
|
|
|
Cause:
|
The specified element references a nonlinear or temperature dependent material property that has resulted in the generation of a non-positive definite material stiffness matrix. The following will result:
- The element stiffness matrix will be non-positive definite.
- The global stiffness matrix may be non-positive definite.
- The solution may not be valid.

|
|
Action:
|
Check the material property tables that define material behavior as a function of stress, temperature, or both.
