Company Overview
COMSOL, Inc. is a Swedish-American software company that develops COMSOL Multiphysics, a cross-platform finite element analysis and simulation environment. Founded in 1986 and headquartered in Stockholm (with U.S. operations in Burlington, Massachusetts), COMSOL specializes in multiphysics coupling — the ability to simulate multiple interacting physical phenomena in a single model.
COMSOL Multiphysics is used by engineers and researchers in structural mechanics, heat transfer, fluid dynamics, acoustics, electromagnetics, and chemical engineering. The platform's Application Builder allows simulation experts to create custom simulation apps for non-specialist colleagues.
Key Capabilities
- Multiphysics coupling: Solve coupled physics problems (e.g., thermal-structural, electromagnetic-thermal, fluid-structure) in a unified model environment.
- Application Builder: Create standalone simulation applications with custom GUIs that can be deployed via COMSOL Server to teams without simulation expertise.
- CAD interoperability: Import geometry from SolidWorks, Inventor, Creo, CATIA, and NX via LiveLink add-ons for bidirectional parametric updates.

Market Position & Strategy
COMSOL competes in the multiphysics simulation market alongside ANSYS and Dassault Systèmes SIMULIA, differentiating through its focus on coupled-physics modeling and the Application Builder. While ANSYS dominates enterprise simulation and SIMULIA leads in non-linear structural analysis, COMSOL's strength lies in solving problems where multiple physics interact — thermal-structural, electromagnetic-thermal, fluid-structure — within a single unified environment.
The Application Builder is a key differentiator: simulation engineers can create custom apps with simplified GUIs that allow non-specialist colleagues to run pre-configured simulations without learning the full COMSOL interface. This capability extends simulation access within organizations. COMSOL is widely adopted in academia for research and teaching, and in R&D departments where custom physics modeling and source-code-level access to solver settings are essential. Users typically pair COMSOL with a CAD tool (SolidWorks, Inventor, Creo) via LiveLink connections for geometry import and parametric updates.
Learning Resources
COMSOL provides training through COMSOL Events, including hands-on workshops, webinars, and the COMSOL Conference. The Application Library (built into the software) contains hundreds of tutorial models with step-by-step instructions. The COMSOL Blog and Discussion Forum are valuable for troubleshooting and modeling techniques.
