In the recent years we investigated the validity and efficiency of coupling high order finite elements schemes for mechanics with the Lattice Boltzmann Method. The results on two dimensional and three dimensional benchmark configurations are very promising and show that an explicit coupling scheme is able to produce results which agree with reference solutions. The solid part was computed by the structural solver AdhoC and the fluid part by the parallel solver VirtualFluids, which is based on adaptive hierarchical grids and component technology. The applicability of the setup to problems in civil engineering such as the fully three dimensional, turbulent computation of a bridge in a storm will be pointed out. Further coupling to a rigid body dynamics engine (PhysicsEngine-pe) leads to the possiblity to compute interaction problems with a huge number of particles. The parallel simulation of the coupled problem is the base for the simulation of a geothermic drilling project where the particles, cut by drilling, influence the fluid behaviour. A free surface Lattice Boltzmann approach coupled with rigid body motions shows further potential and demonstrates the broad applicability of the developed algorithms.     «
