The high performance computing software features the following benefits:

  • Developed for the latest multi-core architecture
  • Increased speed-up and accuracy, using fewer mesh blocks and reduced MPI communication
  • Directional decomposition, improved performance with thread scheduling and dynamic thread balancing
  • Scaling up to 256 cores

The physical models in FLOW-3D/MP 4.2 are based on FLOW-3D v9.4. Read a complete list of FLOW-3D/MP v4.2 features [pdf].

FLOW-3D/MP, first released by Flow Science in 2006, uses multi-block methodology to decompose the computational domain into blocks, which are then distributed among the nodes in a cluster. FLOW-3D/MP v4.2 has been tested extensively on both Windows (Server 2008 and 2008 R2) and Linux systems (RHEL 4 & 5 and SUSE 10 &11). Read more about FLOW-3D/MP v4.2’s high performance computing capabilities.

Flow Science has commenced shipment of this new release to FLOW-3D/MP customers under maintenance contracts.
