  • We will start by creating the Mesh. For this reason, having selected our body, press the FEM mesh from shape by Netgen button. This option uses the Netgen mesher, an open-source tool used for creating high-quality tetrahedral meshes, particularly suited for complex geometries in finite element analysis.
  • In the mesher parameters window we will keep things simple and only change the maximum cell size. The Max Size option defines the largest allowable size for the individual mesh elements. It controls how coarse or fine the mesh will be. A larger Max Size will result in a coarser mesh with fewer elements, which can speed up computations but may reduce accuracy. A smaller Max Size creates a finer mesh with more elements, increasing accuracy but also requiring more computational resources. Set this value to 10 and press apply.
