ULSPH example: Water flow through a complex geometry read from an STL file

This animation illustrates a simulation of Smooth Mach Dynamics (MACHDYN package) where particles representing water are flowing through a complex triangulated geometry read from an STL file. The LAMMPS dump image command supports visualizing this kind of surface by querying the fix smd/wall_surface command for the triangle datasurfaces either as a wireframe mesh or with triangles. The water particles are color coded by their diameter.
