FATAL ERROR E5001

[Anonymous]

I got a "FATAL ERROR E5001 : NON-POSITIVE DEFINITE DETECTED AT GRID 56290 CONPONENT 2" meaage with Prestress Static.

What it means and how to solve it?

Hello,

This error is due to a negative term has been detected on the stiffness matrix factor diagonal during decomposition.

Can you check whether the mesh is continous and also you have defined surface contacts properly?

If possible please post the model here (if it is not confidential) or send it to mahaboob.bashas@autodesk.com.

Thanks!
