Computational Fluid Dynamics Software

SimScale’s cloud-based fluid software enables you to test, validate, and optimize your designs through online CFD.

What is CFD?

Computational Fluid Dynamics (CFD) is the branch of CAE that simulates fluid motion and heat transfer using numerical approaches. Our CFD software can analyze a range of problems related to laminar and turbulent flows, incompressible and compressible fluids, multiphase flows and more. With everything 100% in the web browser, the barriers of limited computing power, accessibility, and high costs are eliminated.
Lattice Boltzmann solver for computational fluid dynamics

GPU-based CFD Solver Using Lattice Boltzmann Method

Transient simulations have historically required a high investment of money and time to provide accurate results. This GPU-based solver uses the Lattice Boltzmann method (LBM) to tackle this problem by pairing high accuracy with unparalleled speed and is accessible via the cloud with SimScale. We partnered with Numeric Systems GmbH to develop this innovative feature through their tool Pacefish®. We have reduced running times for transient simulations from weeks and days to hours and minutes. Its ability to run on multiple GPUs in parallel enables turnaround times that are 20-30 times shorter than standard methods. Moreover, Pacefish® supports several turbulence models such as Smagorinsky, SST-DDES, Hybrid SST-IDDES and k-omega SST making it unique among other LBM solvers. .

CFD modeling of Incompressible flow and Compressible Flow Venturi Injector

Incompressible and Compressible Flow

Under certain conditions, compressibility can become an important consideration. Accurately modeling compressibility is important in order to design better and safer products. The CFD modeling component of SimScale allows the simulation of both incompressible and compressible flow in a robust and accurate way, as our validation cases demonstrate. Applications include airplanes, car spoilers, mufflers, airfoils, injectors, valves, ducts and more.

CFD simulation of laminar flow and turbulent flow in a cyclone separator

Laminar Flow and Turbulent Flow

SimScale supports the CFD modeling of both laminar and turbulent flow regimes. CFD simulation software is used to solve complex flow equations with accurate numerical methods, powerful turbulence models, and intensive computing power are required. SimScale offers everything in one tool, for both steady and transient simulations, with multiple turbulence models, including k-omega SST and k-epsilon. Pipes, cyclone separators, smoke propagation or cleanroom design are among the applications.

Mass transport and thermal transport heat exchanger simulation

Mass and Thermal Transport

Commonly seen in applications like water purification, contamination control or analyzing gas or smoke propagation, passive scalar transport allows performing CFD analysis of matter transport in an incompressible flow. You can simulate mass transport in a fluid flow, applied, for example, in advanced plant simulation. Furthermore, convective and conjugate heat transfer enhance the simulation capability, with a thermal modeling tool for conduction and convection.

CFD simulation of Multiphase Flow Stirred Tank Reactor

Multiphase Flow

The CFD modeling of multiphase or multispecies flow using the volume of fluid (VoF)method for interface capturing is possible. SimScale uses the OpenFOAM solver interFoam which is designed for two non-mixing fluids such as oil or air in a water medium. This approach allows the modeling of laminar or turbulent free surface flows that are often found in marine applications or process engineering.

I loved the fact that I could do what I need to do in a browser. I started working without installing any software. Using any computer I could upload the model and start the analysis. That was the big “wow” moment.
