For high rate of chemical kinetics such as deflagration,fluidyn-MP solves coupled system of momentum and energy equation with a time marching solver.
For detonation of solid explosives, it uses a special density based solver for resolving JWL equations for the explosives. Solver algorithm has been especially developed to build the detonation Chapman-Jouguet front with a minimum number of meshes. Thus a detonation pressure wave, inside a non-spherical 3D geometry of the solid explosives, can also be simulated. Ignition can have a line or point source, giving rise to either cylindrical or spherical waves.
