Our review
Pros	Combines fluid-flow simulation with structural, thermal, acoustic, and other physics. Includes geometry, meshing, CAD interoperability, and engineering integrations. Supports parametric sweeps, optimization, and custom simulation apps.	Combines fluid flow, heat transfer, reactions, and particle dynamics Imports CAD geometry and generates surface meshes Python API automates preprocessing and model setup
Cons	No free plan; prospective customers must contact sales for pricing. The core product is desktop software, not a browser-based modeling environment. Its broad multiphysics scope may be more than teams seeking CFD alone need.	Pricing requires contacting sales Runs on user-managed desktop or server resources No time-unlimited free plan
Our verdict	COMSOL Multiphysics is a desktop environment for creating, solving, visualizing, and evaluating physics-based models. It supports computational fluid dynamics alongside structural mechanics, acoustics, heat transfer, chemical engineering,… Read the review →	M-Star CFD is a computational fluid dynamics package for engineers, scientists, and researchers modeling interacting physical processes.
