The discretized domain, that has to be created by a meshing operation in the Mesh Creator is called mesh. It consists of discrete elements with its faces, edges and nodes. The number of elements and nodes does highly affect the numerical costs of you calculation and the quality of the results. Thus, you can find some general information about the mesh in this section. If you want to modify the mesh e.g. with a local software or use it as input for another tool, you have the possibilty to download it here as well.
