Mesh Generation

Tdyn has been designed and optimised to use linear tetrahedral elements.

Size Assignment

The size of the elements generated is of critical importance. On one hand, too big elements can lead to bad quality results, where on the other hand too small elements can dramatically increase the computational time without significantly improving the quality of the result.

The global element size chosen has been set to 0.1 and an unstructured size transition to 0.6.

The outcome is the unstructured mesh shown in Figure 14, consisting of about 2000 nodes and 10000 tetrahedral elements:
