# 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.
