Since we started using Simerics-MP in 2008, we have been able to start using extensively CFD calculations for Positive Displacement pumps such as vane, gerotor and external gear pumps.What we find great with Simerics-MP is the capability to set-up a complex model very quickly (including CAD model clean up, import into Simerics-MP, meshing and set-up) and be able to get results for a transient analysis in a few hours. This allow us to use the software not only for new projects development but also for troubleshooting. We did validate Simerics-MP with our test-bench data and found that it is very accurate both for global quantities prediction and for local effects like cavitation damage. Overall, we are very happy with the software because it helps raise our department productivity and improve the quality of our work.

The Powertrain Control Research Laboratory (PCRL) is a research group in the Department of Mechanical Engineering, College of Engineering at The University of Wisconsin-Madison. We are using Simerics-MP to evaluate preliminary changes to new hydraulic pump designs for a unique high-speed application. This software allows us to identify the most promising changes, given our goals. Simerics-MP clearly indicated the cavitation and pressure effects of numerous modifications to the pump housing and gears. Development utilizing simulations decreases the design time by negating the need to test each design via a prototype thus severely limiting the required time. Each prototype that is not required for testing eliminates approximately $2,000 toward the development cost.The GUI is simple to use and a single general approach is required to apply a proper mesh and the appropriate set-up parameters. The time required to set up a simulation is approximately 30 minutes. The support provided by Simerics is excellent, top notch, professional, and prompt.
