7.14.1.4. Continuity

Syntax

Eq Continuity 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 Conservation of Mass equation.

Description

The only admissible value for Dof is PRESSURE.

Admissible values of Interp are Q_{1}, Q_{2}, Q_{2S}, P_1, P_0, for standard volume elements and Q_{1}P_{0}, Q_{2}P_{0}, Q_{2S}P_{0}, Q_{1}Q_{1} \text{ and } Q_{1}Q_{2} for shell elements.

Admissible values of Term_n are MASS, LUMPED_MASS, DIV, ADV, SRC, and XFER.

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

The Meshpart must be an active element block.
