like the simulation of the flow around ships. While almost all methods used are based on the Navier-Stokes equations, the discretisation methods for the water surface differ widely. Many of these highly different methods are being used
Compared with the now mature unstructured mesh generation and Cartesian mesh generation, the generation of boundary layer meshes still gives rise to numerous difficulties and is therefore the main challenge in generating the entire prismatic hybrid mesh. Among those difficulties, those induced by the co...
i}=\partial ()/\partial x_i\)as well as Einstein’s summation convention over repeated indices. All field variables are expressed in Cartesian coordinates. The unknowns to be solved are the mass density,\(\rho\), and
