Description

POISSON Poisson equation physics mode definition.

POISSON Define and generate a Poisson physics mode struct. Used with the ADDPHYS function.

Example

  1) Add default Poisson physics mode.

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

  2) Add Poisson physics mode with named dependent variable.

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

[ PHYS ] = POISSON( 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 {u}), mode tag TAG (default poi), and boolean ISAXI to specify 2D axisymmetric formulation (default false).
