7.14.1.14. Porous_Species

Syntax

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

Scope

Aria Region

Summary

The species transport equation porous media. See general porous flow information in Porous Flow Equations.

Description

Admissible value for Dof are PRESSURE, SPECIES, and SPECIES_FRACTION.

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

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

With the exception of XFER these terms are described in Porous Flow Equations.

The Meshpart must be an active element block.

Additionally, one can choose whether to integrate the advection term by parts by setting the flag INTEGRATE ADVECTION BY PARTS = false in the POROUS_FLOW_OPTIONS block of SOLUTION_OPTIONS. The default is true.
