Pore fluid flow

Pore fluid flow can be prescribed in coupled pore fluid diffusion/stress analysis (see Coupled pore fluid diffusion and stress analysis) and in the geostatic stress field procedure (see Geostatic stress state). Pore fluid flow can be prescribed by:

  • defining seepage coefficients and sink pore pressures on element faces or surfaces;

  • defining drainage-only seepage coefficients on element faces or surfaces that are applied only when surface pore pressures are positive; or

  • prescribing an outward normal flow velocity directly at nodes, on element faces, or on surfaces.
