“…This task is correlated with the problem of assessment of the predicted number of volume elements in the final mesh based only on the number of boundary elements. The authors were inspecting a similar problem for a two-dimensional case [13]. A further studies are however necessary for three-dimensional meshes where the prediction will additionally utilize the information from the control space.…”

Abstract. We present solutions for dealing with the problem of parallel generation of unstructured meshes for 3D domains. The selected approach is based on a geometric decomposition of the domain where the input data is given in the form of a surface mesh. The difference between the two presented decomposition techniques lies in the step where the actual partitioning takes place. In the first method the partitioning is obtained using solely the surface mesh while in the latter one a coarse tetrahedral mesh is used. After the decomposition and creation of an interface mesh (which is a surface mesh in both approaches) the final volume meshes are generated independently for each subdomain. The interface mesh and the subdomain meshes are constructed using a Riemannian metric combined with a control space structure which allows to generate meshes with varied density and anisotropy [1].
