By using the different tools in the pre-processing module of Tdyn you can define geometries typical for CAD systems like NURBS or COONS. You can also import standard CAD archives using the IGS and DXF formats.

To help the smoothness of the geometry definition process, Tdyn counts on a variety of CAD tools and options of visualization. Once the geometry definition is finished, the problem data is entered in the same environment of Tdyn. The problem data definition includes the general definitions of the problem, boundary conditions and the mesh generation necessary for the analysis. With Tdyn you have the important control of the mesh generation process, by having the capability to control the size and quality of the elements.

Tdyn saves your time by allowing you to use semiautomatic tasks for the data definition.

As Tdyn can be adapted to the user specific needs, the data definition can be completely automated to make it as easy as possible.
Considering the mesh generation, Tdyn can automate most of this process. Finally, Tdyn provides you with a variety of tools allowing you to have a perfect control over the process and to verify it's quality.

When the pre-processing phase is finished, the Tdyn calculating component is executed in the same user environment. Likewise the results of the analysis are visualized automatically after the calculations are finished.
Tdyn includes different calculating modules covering number of different areas of fluid-dynamic and heat-transfer field. Moreover, Tdyn includes a basic calculation model allowing you to simulate heat-transfer problems in solids.
