Computational Fluid Dynamics

Perform CFD Analysis in your Browser

SimScale is a completely cloud-based simulation software that enables you to test, validate, and optimize your designs through Computational Fluid Dynamics via a standard web browser.

Computational Fluid Dynamics (CFD) is the branch of CAE that allows you to simulate fluid motion using numerical approaches. The cloud-based CFD software component of SimScale allows the analysis of a wide range of problems related to laminar and turbulent flows, incompressible and compressible fluids, multiphase flows and more  — everything 100% in your browser, eliminating the barrier of limited computing power, accessibility and cost. With SimScale, heat transfer, moving and rotating parts and flows in a porous medium can also be investigated. Simulate and optimize your product early in the design phase with the world’s leading cloud-based CAE software.

Incompressible and Compressible Flow

Under certain conditions, compressibility can become a non-negligible factor. Accurately modeling compressibility is important in order to design products better and making them safer. The CFD software 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.

Laminar and Turbulent Flow

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

Mass and Thermal Transport

Commonly seen in applications like water purification, contamination control or analyzing gas or smoke propagation, passive scalar transport allows 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.

Multiphase Flow

The modeling of multiphase or multicomponent flows 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 water medium. This approach allows the modeling of laminar or turbulent free surface flows that are often found in marine applications or process engineering.

Advanced Modeling

SimScale provides tools for modeling a complex fluid flow interacting with rotating parts and porous media. The Computational Fluid Dynamics software component of the SimScale platform will enable you to run simulations with a steady state using rotating boundary conditions and a Multiple Reference Frame (MRF) or unsteady approach using Arbitrary Mesh Interface (AMI).

Fluid - Solid Body Interaction

The simulation of problems involving solid body motion with 6 DoF (Degrees of Freedom) movement is also possible with the SimScale cloud-based CAE platform. Such simulations find applications in understanding the effect of moving fluid on solid bodies and vice-versa. Typical use includes valves and pipes design or shipbuilding.

Christopher Quijano

I have used a lot of simulation packages over the past 25 years, including Nastran, Ansys, SolidWorks, and a whole host of others. I have been using SimScale for about nine months now and it has become my goto simulation tool. It allows me to run models larger than I have ever conceived on my own workstation.
