SimFlow
SimFlow is desktop software for computational fluid dynamics, covering the workflow from mesh generation through post-processing. Simulations stay on the user's hardware, and the software runs on Windows, Linux, and macOS, including Apple Silicon. Jobs can run on a local cluster, remote server, or cloud, with HPC-grade parallel computing and no per-core or hourly charges. The full simulation engine is included in every plan. CAD imports include STL, STEP, IGES, OBJ, and BRep; results can be exported in VTK, Fluent, Tecplot, and Ensight formats. SimFlow integrates with ParaView, OpenFOAM, Docker, and Windows Subsystem for Linux. The free plan has no signup, credit-card requirement, or time limit, but is limited to 200,000 mesh nodes and one CPU. Professional costs €8,000 per year; Enterprise costs €10,000 per year. Commercial plans include a 30-day trial. Perpetual licenses are also available, with one year of maintenance and optional yearly renewals.
