Predictive, fast,


The #1 reason our clients use Cascade’s simulation tools is to better predict traditionally hard problems for CFD: turbulent mixing, flow separation, transition, turbulent shear stress and heat transfer, aeroacoustic noise, combustion and emissions to name a few.

Cascade’s solvers use a time-dependent approach called Large Eddy Simulation (LES) to deliver accuracy and fidelity not found in most commercial CFD tools. Realizing the predictive benefits of LES requires much more than just turning on time-dependence and changing the turbulence model. Cascade’s tools are purpose-built for LES, with high-quality mesh generation that works for real geometries, accurate and stable non-dissipative numerical methods, and accurate modeling for unresolved physics, all within a powerful and scriptable end-to-end workflow.


In the modern design cycle, time-to-solution is a critical metric. No matter how accurate, single simulations that require much longer than one day to complete will find themselves falling behind the design trajectory. Cascade’s solvers are massively parallel and scalable, capable of leveraging large compute resources to get answers in a timely and impactful way. Coupled with powerful pre and post-processing tools, our workflow can deliver the answers you seek with surprising speed.


Cascade’s solvers have always run efficiently on traditional CPU-based clusters, but hardware is rapidly evolving. The exponential growth of high-performance computing has settled — for now — on accelerated node architectures. These systems dominate the top 500 supercomputers, where the vast majority of compute power and memory bandwidth live on GPUs. Cascade’s solvers can efficiently leverage a variety of accelerated-node architectures, realizing significant gains in simulation throughput and potentially large savings in cost and power.
