Sph in a total lagrangian formalism
WebSep 9, 2024 · The general formalism of SPH is first described, then the weakly compressible form of a solution is defined, followed by the incompressible form. Formulations to high order, increasing accuracy, are then summarized. Particle adaptivity for variable resolution is described, although this has received limited attention to date.

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.
