Wettability is a property of materials that plays a major role in everyday and industrial use. However, designing new materials is usually a long and tedious process, which in practice often requires the production of a large number of prototypes. This master thesis presents concepts and implementation of testing the wettability of the surface topology of materials by means of computer simulation of flows. For the flow simulation process, we used the lattice Boltzmann method and optimised it for the GPU. The system was evaluated with Poiseuille flow and tested on surfaces generated by procedural noise functions. We then assessed the wettability using our own algorithm on the volumetric data obtained from the simulations and exposed the correlation between some of the procedurally generated surfaces and the contact angle.
