ADDPHYS Parse and add physics mode to problem struct.
[ PROB ] = ADDPHYS( PROB, F_PHYS, C_DVAR, F_OUT ) Parses and adds the physics mode with function name or handle F_PHYS to the problem struct PROB. C_DVAR prescribes the given instead of default dependent variables names, and the F_OUT flag adds the mode to the PROB struct (default true) or optionally simply returns the computed physics mode struct.
1) Add default Poisson physics mode.
fea.sdim = {'x', 'y'};
fea.geom.objects = {gobj_circle};
fea = addphys( fea, @poisson );
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'} );
