SC/Tetra is a general purpose computational fluid dynamics simulation software based on Finite Volume Method (FVM), and it creates unstructured (tetra-, penta- and hexahedron) mesh. It is the professional choice for complex shaped simulation geometry.
The most important features of SC/Tetra are that it combines the handling of the most complex fluid dynamics problems with an easy workflow from handling CAD geometries to setting boundary conditions of complex physics and creating professional quality mesh. Because of these working with SC/Tetra is fast and effective. It is also important to know that SC/Tetra has very small memory consumption: a mesh of 5 million elements takes only 1 GB RAM. For you it means that on an ordinary workstation you can handle and solve problems with very detailed meshes so your analysis can be very accurate as well.
