SimFlow
SimFlow is desktop software for computational fluid dynamics, covering the workflow 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, but is limited to 200,000 mesh nodes and one CPU. Every plan includes the full simulation engine without add-on modules or feature gating. SimFlow supports local, remote-server, or cloud jobs and HPC-grade parallel computing without per-core or hourly charges; a fully offline license is available for secure environments. CAD imports include STL, STEP, IGES, OBJ, and BRep, while results can be exported in VTK, Fluent, Tecplot, and Ensight formats. It integrates with 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; each includes a 30-day trial. Perpetual licenses are also available.
Who it is for
SimFlow suits people running CFD workflows locally who need mesh generation through post-processing. The free tier is for work within its node and CPU limits; commercial plans add support and training.
