# FE Mesh

### Glossary Term

In FEA calculations, the structure is decomposed into small substructures (finite elements). The construct, which is created by this way and is most similar to the original structure in its essential 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 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.
