SimFlow · Warsaw, Poland
What it is
SimFlow is desktop software for computational fluid dynamics, covering work from mesh generation through post-processing. It runs locally on Windows, Linux, and macOS, including Apple Silicon, and simulations remain on the user's hardware. The free plan has no signup, credit-card requirement, or time limit; it is capped at 200,000 mesh nodes and one CPU. Every plan includes the full simulation engine. Users can run jobs on a local cluster, remote server, or cloud, and the software supports HPC-grade parallel computing without per-core or hourly charges. CAD import supports STL, STEP, IGES, OBJ, and BRep, while results can be exported in VTK, Fluent, Tecplot, and Ensight formats. Integrations include ParaView, OpenFOAM, Docker, and Windows Subsystem for Linux. Commercial plans add support, training, and onboarding. Professional costs €8,000 per year and Enterprise costs €10,000 per year; commercial plans offer a 30-day trial. Perpetual licenses are also available, and an offline license option is available for secure environments. SimFlow is provided by SimFlow Technologies, headquartered in Warsaw, Poland.
