This movie shows the adaptive mesh that is used in the 3d convection simulation shown in • Convection in a 3d box . The mesh is adapted every 15 time steps, and it is obvious how the mesh refinement follows areas where significant flow happens. • The simulation corresponds to convection in a box with heated bottom and cooled top. Solved with the finite element code ASPECT (http://aspect.dealii.org) using the 3dbox.prm input file set up by Timo Heister. Simulation by Wolfgang Bangerth on 64 cores. The simulation has ~10M unknowns and runs for ~10,000 time steps. Further discussion can be found in the Aspect manual.
