Coupled Temp-displacement Convergence problem
Coupled Temp-displacement Convergence problem
(OP)
Hello,
I m analyzing the rapid cooling (about 700C°C/s) of steel plate (thickness 1mm) in Abaqus/Standard.
I have same convergence problem like :
***ISOTROPIC HARDENING PLASTICITY DID NOT CONVERGE FOR ELEMENT PLATE-1
***THE SYSTEM MATRIX HAS 6 NEGATIVE EIGENVALUES
I tried
but i can't have total convergence. What else can I try to eliminate convergences problems?

I tried
- - reduce the size of mesh
- - use automatic stabilization (damping factory)
- - dashpots
but i can't have total convergence. What else can I try to eliminate convergences problems?
