Find optimal designs using topology optimization

Adjoint-based flow topology optimization is an exciting new way to quickly find ideal designs.  With an inbuilt constrained optimization method and an end-to-end workflow, you can now leverage this cutting-edge technology. This allows you to generate highly efficient, and often non-intuitive solutions to your design challenges.

Improve accuracy of process simulations coupling CFD and gPROMS

Improving chemical processes like spray-drying or mixing requires accurate modeling of complex physics and chemistry. gPROMS is a powerful modeling environment to simulate such processes.  You can now easily use CFD simulations from Simcenter STAR-CCM+ 2020.3 to calibrate a multizonal gPROMS model. This improves modeling accuracy and eliminates uncertainty.

Reduce computational cost for hybrid multiphase modeling

With version 2020.3 we’ve introduced an exciting new hybrid multiphase capability. This enables you to more efficiently simulate liquid flows in applications where flow breakup is present, such as vehicle water management or spray cooling. The VOF to Lagrangian transition model resolves the formation of droplets using a Volume of Fluid approach. To track these droplets, the model automatically switches to a Lagrangian method, significantly reducing computational expense and simulation turnaround time.

Design better engine combustion systems with liquid film modeling

High fuel loading in Internal Combustion Engines may cause undesired liquid films to form on surfaces. With version 2020.3 you can now model this phenomenon with Simcenter STAR-CCM+ In-Cylinder Solution. This means better understanding of the performance impacts of high fuel loading, including emissions and pool fires, and leads to better combustion system design.

Speed up simulations of free surface flows with droplets or bubbles

Simcenter STAR-CCM+ 2020.3 also introduces the mixture multiphase large-scale interface model: a new approach to simulate free-surface flows with droplets or bubbles for applications like gear lubrication. This approach removes the need to resolve all relevant scales in the mesh, bringing faster and more accurate answers.

Improve accuracy of unsteady RANS simulations at no additional cost

Finally, the new scale-resolving hybrid turbulence model helps capture more small-scale turbulent structures in an unsteady RANS simulation. This means, for example, increased fidelity of your transient aerodynamics simulations without additional computational cost.
