FLOW-3D is a powerful modeling tool that gives engineers valuable insight into many physical flow processes.  With special capabilities for accurately predicting free-surface flows, FLOW-3D is the ideal 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 list of key features in our latest release, Version 9.2,
