In FEA calculations, the structure is decomposed into small substructures (finite elements). The resulting object, which usually resembles the structure in its basic features, is referred to as the FE mesh. It is comprised of many elements that can differ in dimensions (1D, 2D, 3D) and shape (triangle, quadrangle, tetrahedron …).
The size or number of the elements in the mesh is in proportion to the quality of the results. This means: the smaller the elements you choose, the closer you usually get to the ideal results. This indirect proportional relation also exists between element size and calculation duration. So in everyday engineering practice, the element size is sought that ensures sufficient accuracy and acceptable calculation time simultaneously.
The parameters for generating the FE mesh can be defined in a dialog box.
