PLANESTRAIN Plane strain physics mode.
PLANESTRAIN Define and generate a plane strain physics mode struct. Used with the ADDPHYS function.
  1) Add default plane strain physics mode.
  fea.sdim = {'x', 'y'};
  fea.geom.objects = {gobj_circle};
  fea = addphys( fea, @planestrain );
  2) Add plane strain physics mode with named dependent variables.
  fea.sdim = {'x', 'y'};
  fea.geom.objects = {gobj_rectangle};
  fea = addphys( fea, @planestrain, {'u1', 'u2'} );
[ PHYS ] = PLANESTRAIN( SDIM, DVAR, TAG ) Optional arguments when used without addphys are a cell array of space dimension variables SDIM (default {x, y}), dependent variable names DVAR (default {u, v}), mode tag TAG (default psn).
