Following are some competitive advantages of Tdyn compared to other available CFD software:

Completely integrated pre/post-processing module
Automated assignment of boundary conditions on bodies
Wizard (assistant) type tools that help with a geometry definition, boundary conditions assignments, data introduction, mesh generation and results post-processing.
Tools for fast and effective analyses report creation
Extremely powerful mesh generation of complex geometry models.
Extremely simple data introduction and fast process learning
Extreme flexibility in physical properties and boundary conditions definitions using user-defined functions
New problems generation possibility
Capacity to configure output variables like a function of any internal variable of the program or its derivatives
Optimized triangular and tetrahedral elements use that allow completely automatic mesh generation (it is also possible to use any element type)
Different and optimized solution methods (solvers) that allow solution of problems of a great size using desktop PCs
Possibility of user adaptation based on specific needs
