In their own words
COMSOL Multiphysics
COMSOL Multiphysics is desktop software for simulating designs, devices, and processes in engineering, manufacturing, and scientific research. It supports single-physics and fully coupled multiphysics models, including user-defined physics descriptions and equations. Model Builder covers work from geometry and CAD through physics modeling, meshing, studies, optimization, solving, and visualization. Supported fields include electromagnetics, structural mechanics, acoustics, fluid flow, heat transfer, and chemical reactions.
Model Manager provides version control, storage, search, collaboration, permissions, and support for local or remote server databases. Application Builder lets experts create custom simulation interfaces for collaborators and customers; deploying those applications requires COMSOL Server or COMSOL Compiler. Interfacing products include LiveLink for MATLAB, Simulink, and Excel, as well as CAD links or import tools. The software supports Windows, macOS, and Linux, with offline access, authoring tools, 3D visuals, and data export. It is paid, with pricing on request, and a free trial is available. Customers contact COMSOL to evaluate requirements and choose a license; a sales representative responds within one business day.
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.
