FLOW-3D is a powerful and highly-accurate computational fluid dynamics (CFD) software that gives engineers valuable insight into many physical flow processes. With special capabilities for accurately predicting free-surface flows, FLOW-3D is the ideal CFD software to use in your design phase as well as in improving production processes.
FLOW-3D is an all-inclusive package. No special additional modules for meshing or post-processing are needed. An integrated graphical user interface ties everything together, from problem setup to post-processing. For a description of key features in our latest FLOW-3D release, Version 9.4, go to the What's New in 9.4 section.
