Simcenter SPH Flow software

Applications like electric motor cooling, tire hydroplaning, automotive water management for sensor soiling, water impingement, and rain on windshields, all require an interdisciplinary engineering approach. To cope with the resulting complexity, you need to assess the performance of products across disciplines with integrated simulation solutions.

For many of these applications, computational fluid dynamics (CFD) simulations need to be closely coupled with structural mechanics. Simcenter SPH Flow allows the coupling of smoothed-particle hydrodynamics (SPH) with finite element method (FEM) solvers to simulate fluid-structure interactions. For applications where aerodynamic forces have a relevant impact on the primary (liquid) phase, SPH can be coupled with another SPH simulation or the Simcenter mesh-based CFD methods. This allows you to stay integrated while coping with multiphysics complexity.

Airplane ditching, water wading, gearbox lubrication and dam break scenarios all share the challenge of highly dynamic local effects with steep gradients and a fragmentation of the associated liquid surface.

Local particle refinement in Simcenter SPH Flow enables you to precisely capture areas of interest with higher resolution at lower CPU cost. SPH’s static or moving refinement boxes ensure high-accuracy simulations at low computational and setup effort, hence enabling you to go faster without compromising CFD simulation fidelity.

Gearbox lubrication, vehicle water wading and windshield wipers are just a few examples that are characterized by complex motions.

With the Simcenter SPH Flow motion models for CFD simulations, model the complexity and predict the real-world fluid dynamics performance for such moving objects. Mitigating the need for computational grids, Simcenter SPH Flow empowers you to easily and quickly set up and simulate a broad range of complex body motions. To accurately capture fluid dynamics under transient conditions and moving geometry, Simcenter SPH Flow allows you to simulate the dynamic 6-DOF motion of bodies, including any sort of rotation or translation motions. This allows you to define even the most sophisticated motions with minimum effort to accurately replicate real-world product operation conditions and predict resulting fluid dynamics performance.

There are several areas that require you to simulate fluids dominated by diffusion and viscous or viscoelastic behavior: sealing and assembly processes, slurries, extrusions, material processing, and food and beverage industries that work with mixers.

Simulating rheology CFD accurately is the key to reducing power consumption, emissions and raw material usage while improving product reliability, user experience and liability costs.

Simcenter SPH Flow offers the ability to simulate such applications with non-Newtonian fluids.

The impingement of liquids plays a crucial role in many aerospace, powertrain and automotive applications.

The Simcenter SPH Flow predictive surface tension model accurately captures wettability effects on different surface conditions, for instance by defining highly diverse contact angles to study from hydrophobic to hydrophilic materials. With this high-fidelity model, Simcenter SPH Flow can also predict capillary effects in the narrowest areas.
