Next the mesh of the geometry to be used in the analysis will be generated using lineal tetrahedral elements.
The size of
the elements generated in the mesh step is of critical importance. On the one
hand, too big elements can lead to bad quality results, whereas too small
elements can dramatically increase the computational
In this example the mesh size of the free surface (and the lines and points of this surface) has been set to 0.1 and the hull points, lines and surface to 0.05.
After the size assignment, the mesh is generated selecting the corresponding option (Meshing>Generate) in the menu. The Elements general size has been fixed to 1.0 and the Unstructured size transitions has been set to 0.5.
The resulting mesh of 23157 nodes and 90541 tetrahedra may be too coarse for practical purposes but is more than enough for testing the capabilities of the program.
