FEATool Multiphysics vs SimFlow

FEATool Multiphysics is desktop software for engineering simulation, with tools to model and solve problems across heat transfer, mass transport, structural mechanics, fluid dynamics, and electromagnetics. Models can be built in 1D, 2D, or 3D, including axisymmetric configurations. Geometry tools support modeling and exchange in STEP, IGES, STL, and OBJ formats; meshes can be generated with built-in tools or Gmsh, Netgen, tetWild, and Triangle. FEATool connects its solvers with OpenFOAM, SU2, FEniCS, and redbKIT workflows. Interface actions map to MATLAB functions, and projects can be saved as MATLAB scripts or exported as Python scripts for FEniCS. Results can be exported to MATLAB, CSV, GMV, and VTK, or as interactive ParaView Glance and Plotly web models. It runs as a standalone app on Windows and Linux, or as a MATLAB toolbox on Windows, Linux, and Intel Mac; no standalone macOS app is available. A limited-functionality trial is offered, with full-feature trials requestable for 30 days.

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.
