ABAQUS mesh systems

Submitted by HussamNasreddin on

Hello all,

After performing an analysis step, could I remove an element from the mesh grid(thus, creating a geometrical change in the model) and then run another analsyis step? Is there anyway for ABAQUS to do this without me physically removing the element?

 Thanks

"ELEMENT DELETION" is availble in  Abaqus Explicit



1) User's Manual 23.8.1 User-defined mechanical material behavior

Deleting elements from an Abaqus/Explicit mesh using state variables

Element deletion in a mesh can be controlled during the course of an Abaqus/Explicit analysis through user subroutine VUMAT.

2) Subroutine Manual 1.2.15 VUMAT User subroutine to define material behavior.

Material point deletion

I think the element is preserved in place, but does not contribute to the part stiffness any longer
