PumpLinx is a 3-D Computational Fluid Dynamics (CFD) software developed for the analysis of fluid pumps, motors, compressors, valves, propellers, hydraulic systems and other fluid devices with rotating or sliding components.The software imports 3-D geometry from CAD data in the form of STL files. It has geometry Conformal Adaptive Binary-Tree mesh generation tool which creates 3-D grid from CAD surfaces.
