Abstract (technical / expert description):

Fluids with free surfaces are not only important in various situations during everyday life, e.g. when pouring water into a glass, but also for many productions processes like casting or foaming. This project uses the free surface algorithm developed in the course of the FreeWIHR project, where it is used to simulate the foaming of liquid metals, with the target of adapting and optimizing it for additional applications as computer graphics and nano-technology. 

Due to its computational complexity, the animation of liquids in computer graphics is an active topic of research. We were able to show that the Lattice-Boltzmann method can be used to efficiently produce visualizations of fluid simulations. Furthermore, it can be combined with level set methods to improve the visual quality.

By now the fluid solver developed at the LSS is integrated into the 3D application Blender thanks to a grant from Google.
