  • Simerics Automotive Users’ Meeting

    Simerics Detroit Office took the lead in organizing the first Simerics Users’ Conference. The conference was held immediately following the SAE 2014 conference and focused on the Automotive Industry. More than twenty users, including those from major automotive companies (GM, Toyota, Ford, Chrysler, and Tata Motors) attended the meeting. Based on the response of our users, it was big success for Simerics. Simerics is planning to add this event to its yearly calendar.
    Sincere thanks go out to all participants and presenters!

  • Simerics and PumpLinx at 2014 IFPE Show

    Simerics attended the 2014 IFPE Show   in Las Vegas, NV, March 4-8. The show itself has over 400 exhibitors, including virtually all major pump and valve manufacturers in the Fluid Power Industry.   The technical sessions also had several sessions on Fluid Power components, including a presentation on “Improving the position control performance of a Proportional spool valve, using a 3D CFD modeling [PumpLinx],” by A. Senatore, D. Buono, E. Frosina, University of Naples Federico II, M. Pavanetto, I.I. Costin, Duplomatic Oledinamica S.p.A., and M. Olivetti, OMIQ s.r.l.  That research paper shows excellent agreement between the PumpLinx predictions and experimental data.

    Computer simulations of pumps and compressors can now serve the same function as hardware testing. These simulations can be done in less time with less cost while providing engineering data of similar quality as experiments. Furthermore, computer modeling can be performed directly by the engineer doing the hardware design, thus providing a tight link between analysis and design optimization. Virtual testing can also be used to analyze problems with existing hardware, either as standalone components or in the context of a system. This presentation focuses on PumpLinx, a Computational Fluid Dynamics (CFD) tool that serves as a virtual test bed. PumpLinx predicts the performance of pumps and compressors in terms of head rise, power, efficiency, cavitation effects, noise, and/or damage. PumpLinx starts with existing designs created in a third party CAD package. Once the geometry is imported, the pump is meshed, modeled, simulated and analyzed, all in a single interface. Various operating conditions and fluid properties can be input to simulate the pump or compressor over a range of operating conditions. The output is similar to what would be measured for a fully instrumented test, with additional flow visualization and integrated quantities. This presentation will provide selected examples of the simulation of compressors and pumps.

  • Evaluation of PumpLinx® by HMS Group Published in World Pumps.

    HMS Group Russia conducted an evaluation of PumpLinx in comparison with test data for several of their centrifugal and mixed-flow pumps. Selected results are presented in the article “Cost cutting with pump performance prediction”, published in the July/August 2013 edition of World Pumps . A copy of the article is available via the World Pumps’ download site.

    Based on the evaluation, HMS had the following testimonial for PumpLinx,

    “PumpLinx for me has surpassed all expectations: 3D model preparation – 2 hours maximum, 1 hour on average. No problems with mesh creation – always created and there are no errors in the calculations because of the quality of the grid. Calculation of the first characteristic point is no more than 10-30 minutes, which is 10-30 times faster than our main program. Accuracy of the calculation for the pressure and for the efficiency in the range of 1% to 3% max (in the operating range of feeds, and for one pump and throughout the feature). To sum up the total: a great program for the engineer;quick and easy; Overall evaluation of 9 out of 10 (with 10 being a perfect virtual [Score])”
