Anneal Mesh on Output

Anneal Mesh on Output = {yes | no}

Description / Usage

This optional card enables the user to specify that the mesh displacements should be set to zero for the next continuation step. Valid options for this input card are

yes

Set the mesh displacements to zero for the next continuation step.

no

Do not set the mesh displacements to zero for the next continuation step. This is the default.

There are two important restrictions: 1) annealing the mesh will not work for the TOTAL_ALE mesh motion types, and 2) only the last time step will be annealed for transient problems.

Examples

Following is a sample card:

Anneal Mesh on Output = yes

Technical Discussion

Annealing a mesh is accomplished by adding the displacements (from the solution) to the base positions (from the FEM file) and writing the resulting nodal positions to a new EXODUS II file, currently anneal.exoII. During the annealing process, the displacement field is also set to zero. This file would be used to restart a subsequent analysis where the anneal.exoII is copied to, or becomes, the file used in a read_exoII option for an Initial Guess.
