About
COMSOL Multiphysics is an industry-leading multiphysics simulation software developed since 1986, trusted by engineers, researchers, and educators worldwide. It provides a unified modeling environment where users can build geometry, define physics, set up meshes, run solvers, and analyze results — all within a single, consistent interface regardless of the engineering application. The platform supports a broad range of physics disciplines through specialized add-on modules, including electromagnetics, structural mechanics, acoustics, fluid flow, heat transfer, and chemical engineering. GPU-accelerated and HPC-ready solvers ensure fast, scalable simulations for demanding computational workloads. Beyond core simulation, COMSOL offers the Application Builder for creating custom simulation apps, COMSOL Compiler™ for packaging apps as standalone executables, and COMSOL Server™ for browser-based deployment across an organization. These tools make it easy for simulation experts to share digital twins and apps with non-expert stakeholders. COMSOL is used across industries including automotive, aerospace, electronics, biomedical, energy, and academic research. Version 6.4 introduced GPU-accelerated simulations, time-explicit structural dynamics, and a new product for granular flow. With 500+ employees and 16 global offices, COMSOL is a cornerstone tool for high-tech product development, academic research, and advanced engineering education.
