COMPRESSIBLEEULER Compressible Euler equations physics mode.
COMPRESSIBLEEULER Define and generate a compressible Euler equations physics mode struct. Used with the ADDPHYS function.
1) Add default compressible Euler equations physics mode.
fea.sdim = {'x', 'y'};
fea.geom.objects = {gobj_circle};
fea = addphys( fea, @compressibleeuler );
2) Add compressible Euler equations physics mode with named dependent variables.
fea.sdim = {'x', 'y', 'z'};
fea.geom.objects = {gobj_block};
fea = addphys( fea, @compressibleeuler, {'rho0', 'u2', 'u3', 'p'} );
[ PHYS ] = COMPRESSIBLEEULER( 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 {rho, u, v, p}), mode tag TAG (default ee), and boolean ISAXI to specify 2D axisymmetric formulation (default false).
