# 7.14.1.8.7. Darcy_Solvent

Syntax

  Bc Dirichlet For Dof Name [{of} SpeciesName | {in} MaterialPhaseName | {ls} {a | b | c}] {@ | at | for | on | over} Mesh Extent Name [Touching TouchingMeshExtent | Opposing OpposingMeshExtent] = Darcy_Solvent [Using Data Specification Data Spec Name] [Gx = gx | Gy = gy | Gz = gz | Relative_To = relative_to]

Summary

  This model is intended for problems where the porous species equation is being solved for pressure with a solvent species concentration as the mass term in order to solve for the velocity of that solvent species.
