7.14.1.7. Extension_Speed

Syntax

Eq Extension_Speed 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 an equation for extension speed, which is used by the level set equation (Level Set/CDFEM) to define the interface speed.

Description

The only admissible value for Dof is EXTENSION_SPEED.

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

Admissible values of Term_n are DEF, SRC, and XFER.

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

The Meshpart must be an active element block.
