Sph in a total lagrangian formalism
WebAs a result, the standard SPH kernel function is called Eulerian kernel even though that SPH is a Lagrangian particle method. In SPH the conservation equations of mass, momentum and energy as shown in equations 1, 2 and 3 are solved at each time step in the current configuration or frame.
