In fire safety science and engineering, the Fire Dynamics Simulator (FDS) is a well established tool, which encounters limits at complex geometries and large-scale problems because of static, structured meshes.To overcome these, a new approach using the Finite Element Method (FEM) with unstructured meshes and adaptive methods with a dynamic mesh resolution will be presented.The underlying model is presented along with its numerical implementation. First attempts in the verification of the flow solver are presented and compared to FDS. A demonstration of adaptive mesh refinement and the scaling on the JURECA supercomputer is shown. |
