7.14.1.11. Mesh

Syntax

Eq Mesh for Associated DoF [{of} SpeciesName | {in} MaterialPhaseName | {ls} {a | b | c}] {on} MeshPart using Interp with {Term_0} … {Term_N}

Scope

Aria Region

Summary

Activates the pseudo-solid mesh equation (see Conservation of Solid Momentum).

Description

The only admissible value for Dof is MESH_DISPLACEMENTS.

Admissible values of Interp are Q_{1}, Q_{2}, Q_{2S}.

Admissible values of Term_n are DIFF, REF_DIFF, TSTRAIN, SRC, and XFER.

With the exception of XFER these terms are described in Generalized Conservation Equation.

If both the MESH and SOLID equations are defined in the same region, then the TALE mesh motion algorithm is activated automatically. In this case, the MESH equation must be defined on all blocks in the region. More details of the TALE method can be found in Conservation of Solid Momentum.

The Meshpart must be an active element block.
