Why Simerics-MP/MP+ CFD Matters to You

Simerics provides very fast and accurate virtual testing for the analysis and performance prediction of a large number of different types of pumps, compressors, vacuum systems, motors, turbomachinery and complete fluid systems with rotating/sliding/moving components. Even with complete systems, combined flow and thermal/CHT can be simultaneously solved. Highly developed algorithms, templates, workflow automations, and built-in intelligence significantly reduce the time required to complete projects.

With legacy CFD solutions, Analysts and Engineers spend extensive periods of time on CAD model simplification and cleaning up geometry. Simerics users experience simplicity and time savings throughout geometry prep, meshing, solving and post-processing. For very complex equipment, time savings and accuracy are even greater as compared to legacy solutions.

Greater efficiency provides more valuable use of one of your most valuable resources - your engineering team. By completing projects within much shorter time periods, opportunities for optimization, innovation and improved performance are greatly enhanced.

Physics

Steady-State/Transient

Fast and accurate steady-state or transient analyses with ultra fast conversion from steady-state to transient during the solving process. Able to model complex features and very small gaps/clearances down to the micron-level.

Multiphase

Gas, liquid, solid interactions and/or different gasses and fluids. Multiphase flow and heat transfer uses Volume of Fluid (VOF) approach with high resolution interface capturing algorithm. Both implicit and explicit approaches are fast and robust with sharp phase interface and excellent mass/volume conservation for each phase.

Internal/External Flow

Compressible/incompressible, laminar/turbulent, steady/unsteady from creeping to supersonic. Using a RANS finite volume-based approach, it also solves non-Newtonian fluid as well as fluids with variable properties such as real gas. Able to converge extremely difficult problems, even those with detailed micro-scale features and/or severe cavitation.

Free Surface

Efficient, precise free surface modelling. Uses VoF solver and multiphase module. Tracks the interface between immiscible fluids with conserved liquid mass. Accounts for surface tension effects, gravity, compressible gas behaviors, etc.

Dynamics

Predict dynamics of moving parts in fluid systems in response to fluid pressure, inertia, spring forces, magnetic forces, fluid shear and other forces.

Particle

Simulate movement of individual particles of varying size and mass including wall functions, gravity, two-way force coupling between particles and fluids, etc.

Cavitation

Extremely accurate cavitation accounting for liquid vapor, non-condensable gas, and liquid compressibility to form a very comprehensive cavitation and aeration model. Transition of non-condensable gas between dissolved and free states is included in the model.

Thermal/CHT

Model conduction, radiation, free and forced convection. Predict conjugate heat transfer (CHT) through different fluids and solids materials in contact.

Species

Model the diffusion and transport for mixtures composed of multiple species or solve any simple scalar equation with source terms and diffusive/convective transport.

How Simerics Delivers New High Levels of CFD Analysis Efficiencies for Pumps - Compressors - Vacuum Systems - Turbomachinery

Accurately simulating pumps, compressors and turbomachinery can be very time-consuming and challenging. Simerics-MP/MP+ greatly simplifies and compresses the entire CFD simulation cycle by using one intuitive and simple GUI throughout all phases of the workflow, including pre-processing, meshing, solving and post-processing.

Geometry clean-up and simplification are often not required, but when desired, engineering time is greatly reduced through intelligent, built-in automations and assistants.

Meshing is also greatly simplified and extremely efficient. The highly intelligent, template-based, autonomous meshing is best-of-breed and very quickly creates high-fidelity, accurately resolved, body-fitted meshes that rarely require manual adjustment. This applies even to moving/sliding/MRF grids for extremely complex geometries and micron-level gaps or clearances.

A very robust, fast and stable solver serves to accelerate processing. Coupled with parallel post-processing, results are generated in a fraction of the time, which is especially useful for trimming times with transient, multi-phase and VoF studies.
