Mesh Generation

Tdyn 2D has been designed to use linear three node triangular elements.

Size Assignment

The size of the elements generated is of critical importance. Too big elements can lead to bad quality results, whereas too small elements can dramatically increase the computational time without significantly improving the quality of the result.

In order to generate the mesh select the option shown in Figure 23. You will then be asked for the global element size (0.1 in this case).

The outcome is the unstructured mesh shown in Figure 24, consisting of 124 nodes and 206 triangle elements:
