The most powerful feature of APUS-CFD is its solver. It is a state-of-the-art polyhedral, segregated flow and heat transfer solver for complex geometries. Its robustness is demonstrated in solving problems on 'poor' quality meshes that the most popular CFD solvers fail to perform. There is a choice of first-order upwind schemes, for fast solutions or higher-order schemes for improved accuracy.

The benefits of Parallel CFD can be fully exploited by using APUS-CFD. Running in parallel is transparent, computationally efficient and provides identical results to those with serial runs. The automatic mesh partitioning gives the best possible load balancing and minimum communication overheads, therefore delivering maximum performance.

APUS-CFD is one of the few commercial solvers adapted to run on the Grid. This has been achieved via the FlowGrid infrastructure (EU funded project). FlowGrid is a complete solution for setting up and running CFD simulations on the Grid. It is a complete system that hides all the details of a grid infrastructure and associated software, and allows the users to concentrate on their CFD simulations as they would do on their desktop computer.
