Simerics-MP+ for PD

Simulation Software for Positive Displacement (PD) Compressors, Pumps, Motors, and more


Simerics®-MP+ for PD is a 3-D Computational Fluid Dynamics (CFD) tool that provides accurate virtual testing for the analysis and performance prediction of Positive Displacement Compressors, Pumps, Motors, and associated Systems.  For liquid systems, Simerics®-MP+ for PD’s proprietary Cavitation Module accurately models vapor, free gas and liquid compressibility to enable the analysis of performance, pressure ripple, and cavitation damage.

  • Comprehensive physics

    Flow, turbulence, conjugate heat transfer, real gases, aeration, cavitation, particles.

  • Accurate predictions

    Excellent correlation with test data over the full operating range.

  • Fast model creation, even faster simulation speed

    Less than an hour from “dirty” CAD to simulation.

  • Able to model complex details down to the micro scale

    Accurately model leakage gaps, tip clearances, balance holes, etc.


Simerics®-MP+ for PD is built on Simerics-MP’s baseline technology to provide a transient 3-D simulation software uniquely suited for the analysis and design of Positive Displacement Devices.

  • Result Accuracy

    Accurate Results:

    Simerics®-MP+ for PD consistently provides simulation predictions that are within 5% of physical hardware test results over the full operating range. (Testimonial)

  • Cavitation

    Superior Cavitation/Aeration Module:

    Simerics®-MP+ for PD rigorously and independently accounts for the formation, transport, and effects of non-condensable gases (e.g. air) and cavitation vapor, as opposed to using a lumped effective compressibility approach. (Testimonial)

  • Convergence

    Fast Calculation Times:

    Simerics®-MP+ for PD has repeatedly been shown to be more than 5 times faster than other commercial codes, enabling more complex simulations. (Testimonial)

  • Robust Solver

    Robust Solver:

    Simerics®-MP+ for PD is able to converge extremely difficult problems, even those with detailed micro-scale features and/or severe cavitation. (Testimonial)

  • Easy of Use

    Ease of Use:

    Less than 30 minutes is typically required to create a model with the aid of templates, automated mesh generation and a single GUI for set-up, simulation, and post-processing. (Testimonial)

  • Support

    Virtually Unlimited Support:

    Simerics®-MP+ for PD comes with extensive training and virtually unlimited support in helping set-up cases. (Testimonial)
