Phase_Change

Syntax

Bc Interface For Energy [{of} SpeciesName | {in} MaterialPhaseName | {ls} {a | b | c}] {on} Mesh Extent Name [Touching TouchingMeshExtent | Opposing OpposingMeshExtent] = Phase_Change [Using Data Specification Data Spec Name] [Toggle = toggle]

Summary

Applies a energy flux to an interface based on phase change, as q = v \rho_{s} (T_{s} C_{p,s} - T_{g} C_{p,g} + L) to sides s and g of the contact interface where v is the velocity \rho is the interface density C_{p} is the specific heat and L is the latent heat of fusion.

Description

The following options are present in most boundary conditions/sources. The meaning of each option is as follows:

Toggle

If given, specifies which toggle block controls whether this BC is active or not.
