SPH to Grid: a new integral conserving method

Understand

Analysing data from Smoothed Particle Hydrodynamics (SPH) simulations is about understanding global fluid properties rather than individual fluid elements.

• Therefore, in order to properly understand the outcome of such simulations it is crucial to transition from a particle to a grid based picture.
• In this paper we briefly summarise different methods of calculating a representative volume discretisation from SPH data and propose an improved version of commonly used techniques.
• We present a possibility to generate accurate 2D data directly without the CPU time and memory consuming detour over a 3D grid.
