CONVECTIONDIFFUSION Convection and diffusion physics mode definition.
CONVECTIONDIFFUSION Define and generate a convection and diffusion physics mode struct. Used with the ADDPHYS function.
1) Add default convection and diffusion physics mode.
fea.sdim = {'x', 'y'};
fea.geom.objects = {gobj_circle};
fea = addphys( fea, @convectiondiffusion );
2) Add convection and diffusion physics mode with 3 named dependent variables.
fea.sdim = {'x', 'y', 'z'};
fea.geom.objects = {gobj_block};
fea = addphys( fea, @convectiondiffusion, {'c1', 'c2', 'c3'} );
[ PHYS ] = CONVECTIONDIFFUSION( SDIM, DVAR, TAG, ISAXI ) Optional arguments when used without addphys are a cell array of space dimension variables SDIM (default {x, y}), dependent variable names DVAR (default {c}), mode tag TAG (default cd), and boolean ISAXI to specify 2D axisymmetric formulation (default false).
