Description

DARCYSLAW Darcy's law physics mode.

DARCYSLAW Define and generate a Darcy's law physics mode struct. Used with the ADDPHYS function.

Example

  1) Add default Darcy's law physics mode.

  fea.sdim = {'x', 'y'};
  fea.geom.objects = {gobj_circle};
  fea = addphys( fea, @darcyslaw );

  2) Add Darcy's law physics mode with named dependent variable.

  fea.sdim = {'x', 'y', 'z'};
  fea.geom.objects = {gobj_block};
  fea = addphys( fea, @darcyslaw, {'p0'} );

[ PHYS ] = DARCYSLAW( SDIM, DVAR, TAG, ISAXI ) Optional arguments when used without addphys are a cell array of space dimension variables SDIM (default {x, y}), dependent variable name DVAR (default {p}), mode tag TAG (default dl), and boolean ISAXI to specify 2D axisymmetric formulation (default false).
