FE Mesh
Glossary Term
It is comprised of many elements that can differ in dimensions (1D, 2D, 3D) and shape (triangle, quadrangle, tetrahedron...).
The size or the number of the elements in the mesh is in proportion to the quality of results. This means that the smaller you choose the elements, the closer you usually get to the ideal results. This indirect proportional relation also exists between the element size and the calculation duration. So in everyday engineering practice, the element size is sought that ensures sufficient accuracy and acceptable calculation time at the same time.

For relatively large or relatively small surfaces, it can happen that the automatically created result values do not fit the model: In case of large surfaces, there can be too much result values, in case of small surfaces, too few.

Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
