Mesh refinement

The finer the finite element mesh is, the more accurate the obtained results are (i.e. the closer to the theoretically correct ones) and the more time consuming the solution is and the more disk space is needed both during the calculation and for storage of the results. The mesh size should be adjusted considering the load the structure is subject to and taking account of the requirements on the calculation.

The generation of the mesh is based on the adjusted size for 2D elements. The generator creates such elements whose edge size is as close to the adjusted value as possible. Also the division of slab / shell borders and internal edges is based on this. Any internal nodes of slabs / shells are taken into account as well.

The mesh must be made finer in certain areas. The mesh may be refines in a circular area around a specific point, in a band along a defined line or over the whole slab / shell.

If any two refinement areas overlap anywhere, the smaller element size is used. The refinement area does not have be fully inside the "master" slab /shell. Only a part of the refinement area may be located inside it.
