APUS-CFD was designed from a clean sheet, using Object-Oriented techniques, and it has been written in C++. Applying state-of-the-art software engineering techniques, the code is modular, extensible and easily maintainable.

APUS-CFD provides a 'truly' integrated, interactive analysis environment that is unique compared to other CFD software. The integrated model builder, mesh generator, pre-/post-processor, solver and real time visualisation, allows the user to:

• Build complex models from pre-built assemblies and imported STL files or other CAD geometries;
• Generate automatically high-quality hexa-dominant meshes from complex geometries;
• Read meshes from Fluent/Gambit and ICEM-CFD;
• Interact with the system in real time, allowing to change solution parameters, without stopping the solver execution;
• Visualise field values (contours and vector displays) while the solution progresses;
• Access and post-process the solution data in a flexible manner (contours, vectors, iso-surfaces, streamlines, XY plotting).

• Advanced discretisation techniques (a collection of first and second order schemes);
• Innovative algorithms and robust solvers for fast convergence.

• Very flexible and easy user-programming, for the addition of new physical and numerical features as well as defining boundary conditions and source terms;
• General polyhedral cell formulation allows the solution on all mesh types;
• Intuitive approach in defining boundary conditions and attaching them to geometrical objects.

• Scalable parallel performance on Linux/Windows clusters and Massively Parallel Computers;
• Unique Grid-Computing capabilities and Remote Execution.

APUS-CFD is an engineering design and analysis tool of the future and our philosophy is that this tool should be made available to designers, engineers, consultants, academics and students who wish to benefit from accurate simulations. We distribute APUS-CFD at an affordable price, breaking the rule that CFD is an expensive and exclusive tool. Check our Licensing schemes and Prices

APUS-CFD is currently ported to Windows XP (GUI and Solver), Linux platforms (Solver) and SGI Altix (Solver). A C++ compiler is required for user-programming option.
