Our best software -
at your disposal
Currently, we offer the following program packages:
- Snas3D is intended for an efficient simulation of three-dimensional flows on structured grids. The body-conform grids may consist of any number of blocks, enabling the treatment of relatively complex geometries. Thanks to various numerical methods available in the flow solver, the user can simulate a wide range of stationary, as well as unsteady flows. A well proven turbulence model is also built in. The software package further contains tools for the processing of grids (block splitting, conversion), generation of the initial solution, and for the preparation of visualization data. Provided is also a tool for the generation of structured grids in axial blade passages. The complete package can be downloaded for free and utilized for non-commercial or for evaluation purposes. Various commercial options, including purchase of the source codes, are also offered.
- MoveGrid - tool which allows you to move or to deform three-dimensional, unstructured, mixed-element grids. It is intended for flow simulations with moving boundaries (moving flaps and rudders, flutter, etc.), or where grid boundaries are reshaped by an optimizer. The package consists of a standalone program and a library with the same functionality. Thus, you can either use the program to move / deform the grid according to given boundary conditions, or you can do the same by calling the library from your own software. The algorithm employs linear elasticity equations of solid mechanics to move the grid nodes, which guarantees valid grid even in cases of large deformations and sheering. Thanks to a novel numerical formulation, the tool can handle grids consisting of a mix of tetrahedra, prisms, pyramids and hexahedra directly and efficiently.
