What Is COMSOL Multiphysics?

COMSOL Multiphysics is simulation software for modeling and analyzing real-world designs, devices, and processes in a single desktop environment. It combines finite element solvers with dedicated physics interfaces for electrical, mechanical, fluid, thermal, and chemical applications across research, engineering, and product development workflows.

The platform provides tools for building parametric models, coupling multiple physics simultaneously, and probing results for verification and optimization. Simulation specialists, engineers, and scientists use it to evaluate product behavior, study physical phenomena, and support decision-making in industrial, academic, and R&D settings.

What Can You Simulate with COMSOL?

COMSOL covers a broad range of physical domains within a single modeling environment:

• Electromagnetic fields, inductors, sensors, and EMC in electronic components
• Structural stresses, deformations, vibrations, and fatigue in mechanical assemblies
• Heat transfer, cooling channels, and thermal stress in devices and enclosures
• Laminar and turbulent fluid flow, mixing, and pressure distribution
• Reacting flows, electrochemistry, mass transport, and battery behavior
• Microfluidics, biosensors, and coupled transport in biomedical devices
• Sound fields, resonance, and vibroacoustic behavior in acoustic systems

Key Features

Model Builder and Study Workflow

The Model Builder provides a unified interface for building geometries, assigning materials, defining physics, generating meshes, and configuring studies. All model components — geometry, physics settings, mesh, and solver configuration — are managed within a single sequential workflow, ensuring consistent and reproducible multiphysics simulation models.

Multiphysics Coupling

Predefined multiphysics interfaces allow electrical, mechanical, fluid, thermal, and chemical physics to be coupled within a single model. These couplings capture interactions between physical domains — such as thermal expansion from Joule heating or fluid-structure interaction — without requiring manual equation linking.

Meshing and Solver Options

Structured and unstructured mesh generation handles complex 3D geometries with local refinement in regions of strong gradients — stress concentrations, thermal boundary layers, or flow separation zones. Solver options include stationary, time-dependent, eigenfrequency, and parametric study types, with direct and iterative solvers for models ranging from small to large scale.

Postprocessing and Visualization

Results are visualized through surface, volume, slice, and streamline plots, along with derived quantities and probe evaluations. Postprocessing tools support design comparison, parametric result overlays, and report generation for documentation of simulation outcomes.

Parametric Sweeps and Optimization

Parametric sweep studies systematically vary model parameters across defined ranges to explore design spaces and identify performance-optimal configurations. Optimization studies automate the search for parameter combinations that meet specified engineering targets.

Equation-Based Modeling

Custom partial differential equations can be defined in weak form directly within the modeling environment. This extends the built-in physics interfaces to capture specialized phenomena, proprietary material models, or non-standard boundary conditions not covered by predefined interfaces.

Application Builder

The Application Builder packages complex simulation models into standalone applications with custom input forms, result views, and report templates. Applications provide a controlled interface for running simulations without exposing the underlying model structure.

Model Manager

Model Manager organizes simulation projects, tracks version history, and supports component reuse across a growing library of multiphysics studies. It maintains consistent workflows in environments where multiple models and study variations are developed in parallel.

Supported Physics and Add-On Modules

The COMSOL platform is structured around a core simulation environment with optional physics-specific add-on modules. The following physics domains are covered by dedicated module families:

• Electromagnetics: AC/DC, RF, Wave Optics, Ray Optics, Plasma
• Structural Mechanics: Structural Mechanics, Nonlinear Structural Materials, Fatigue, Rotordynamics
• Acoustics: Acoustics Module (pressure acoustics, structural acoustics, aeroacoustics)
• Fluid Flow: CFD, Microfluidics, Subsurface Flow, Molecular Flow
• Heat Transfer: Heat Transfer Module
• Chemical Engineering: Chemical Reaction Engineering, Electrochemistry, Battery Design, Corrosion
• Multibody Dynamics: Multibody Dynamics Module
• Geomechanics: Geomechanics Module

The base platform includes core FEM solvers and the Model Builder workflow. Module availability depends on the version purchased — the modules bundled with each version in this store are as originally distributed with that release.

CAD Import and File Compatibility

COMSOL Multiphysics imports geometry from standard CAD exchange formats and, with the appropriate import module, from native CAD files:

• Neutral formats: STEP (.stp, .step), IGES (.igs, .iges), ACIS (.sat), Parasolid (.x_t, .x_b)
• Mesh formats: NASTRAN, STL, VRML, PLY
• Native formats (via CAD Import Module): SolidWorks, Inventor, AutoCAD, PTC Creo, Siemens NX, CATIA V5
• Native format: COMSOL model files (.mph)
