SimFlow is a general purpose desktop CFD software with an intuitive interface combining a full simulation suite in one package. CAD import, meshing, simulation setup, and post-processing.
SimFlow covers many CFD applications including aerodynamics, hydrodynamics, heat transfer, multiphase flows, particle tracking, combustion, and many more.
Yes. SimFlow Free version is available at no cost with no time limit. You get access to all physics models and CFD applications with a 200,000 mesh node limit and 1 CPU core.
When you are ready to scale, upgrade to a commercial plan for unlimited mesh, unlimited CPUs, and professional engineering support.
We also offer a free 30-day trial of the commercial version so you can test it on your cases before committing.
Start with SimFlow Free and download it right away. No registration and no time limit. All physics models and applications are included so you can evaluate SimFlow on your own cases.
Follow our step-by-step tutorials to get up and running quickly with ready-made examples covering meshing, simulation setup, and post-processing.
Need more power? Request a free 30-day trial of the commercial version with unlimited mesh and unlimited CPUs.
Yes. SimFlow is designed around an intuitive interface where every step of the simulation workflow is visual.
Tutorials, example projects, and documentation help you get productive quickly. Most users run their first simulation within minutes of downloading.
SimFlow supports incompressible and compressible flow, turbulence modeling (RANS, LES, DES), heat transfer and conjugate heat transfer, multiphase flows (VOF, Euler-Euler), particle tracking (Lagrangian), species transport, and combustion.
Common use cases include external aerodynamics, HVAC, hydrodynamics, mixing, and thermal management.
Professional single-seat license is 8,000 EUR/year. Enterprise floating license is 10,000 EUR/year.
Both include unlimited mesh, unlimited CPUs, and full engineering support. SimFlow Free is available at no cost with no time limit.
SimFlow is a desktop CFD software, however you can install SimFlow on your chosen cloud provider such as AWS.
Coming 2026: Native cloud support to delegate computations to the cloud or any machine in your organization directly from your desktop.
SimFlow has one price per license with no additional fees. You can run multiple simultaneous simulations on hundreds or even thousands of CPU cores without paying extra for HPC.
No HPC fees, all modules in one package, free version, 30-day commercial trial, professional engineering support, and runs on Windows, Linux, and macOS.
Easy to learn, easy to use, easy to switch.
SimFlow offers flexible licensing to fit your workflow.
Single-Seat / Floating. Lock to one machine or share across your team with a network license server.
Annual / Perpetual. Subscribe yearly with updates included, or buy once and own it forever.
Online / Offline. Activate via internet or use an offline license file for air-gapped environments.
SimFlow runs natively on Windows, Linux, and macOS (Apple Silicon). One license covers all platforms. Install and switch freely.
Same physics engine, same applications, and regular updates for both versions.
Free: 200,000 mesh nodes, 1 CPU core.
Commercial: unlimited mesh, unlimited CPUs, and engineering support.
Every commercial license includes professional support, along with training and engineering consulting for teams with specific simulation needs. Our support team can also prepare custom tutorials and materials tailored to your project.
Documentation, tutorials, and example projects are available for all users.
