'''COMSOL Multiphysics''' (formerly '''FEMLAB''') is a [[finite element]] analysisanalyzer, solver, and solver [[simulation software]] package for various [[physics]] and [[engineering]] applications, especially coupled phenomena, or [[multiphysics]].Coupled COMSOLmode Multiphysics also offers an extensive and well-managed interface to [[MATLABtheory|coupled]] phenomena and its toolboxes for a large variety of [[programming]],Multiphysics preprocessing and postprocessing possibilitiessimulation|multiphysics. A similar interface is offered to [[COMSOL Script]]. The packagessoftware are cross-platform ([[Microsoft Windows|Windows]], [[Macintosh|Mac]], [[Linux]], [[Unix]].) In addition tofacilitates conventional physics-based user- interfaces, COMSOLand Multiphysicscoupled alsosystems allowsof forpartial enteringdifferential coupled systems ofequations ([[partialPartial differential equation|PDEs]]s (PDEs).

Beside the classical problems that can be addressed with application modules, the core Multiphysics package can be used to solve [[Partial differential equation|PDEs]] in weak form. An API for [[Java (programming language)|Java]] and [[MATLAB]] can be used to control the software externally. The program also serves as an application builder for physics applications. Several modules are available for COMSOL,<ref>{{cite web|title=COMSOL Modeling Software|url=https://www.comsol.com/|website=COMSOL.com|publisher=Comsol, Inc.|accessdate=20 November 2015}}</ref> categorized according to the applications areas of Electrical, Mechanical, Fluid, Acoustic, Chemical, Multipurpose, and Interfacing.

COMSOL was started by graduate students to [[Germund Dahlquist]] based on codes developed for a graduate course at the [[Royal Institute of Technology]] (KTH).<ref name="siam-obit">[http://www.siam.org/news/news.php?id=54 SIAM Obituary - Germund Dahlquist]</ref>

=== AC/DC Module ===

Simulates electrical components and devices that depend on electrostatics, magnetostatics and electromagnetic quasi-statics applications, particularly coupled to other physics. Consists of specific interfaces for rotating machinery applications and SPICE circuits lists import.

=== Acoustics Module ===

Contains built-in application modes and boundary settings for the modeling of acoustic propagation in solids and stationary fluids. Also models aeroacoustic applications in moving fluids.

=== CAD Import Module ===

Facilitates the reading of most industry-standard CAD formats. Includes add-in packages that support the file formats for specific CAD programs' geometry kernels.

=== Chemical Engineering Module ===

Analyzes CFD and mass and energy balances coupled to chemical reaction kinetics. Incorporates a plethora of application models for the field of transport phenomena including ionic transport and multi component diffusion.

=== Earth Science Module ===

Models single and coupled processes for geological and environmental phenomena particularly based around subsurface flow. Ideal for porous media flow coupled to other physics such as poroelasticity applications.

=== Heat Transfer Module ===

Consists of advanced application modes for the analysis of heat transfer by conduction, convection and radiation. Specific for industrial applications such as electronics cooling and process engineering.

=== Material Library ===

Internal material property database with more than 2500 materials and 20000 properties. The database contains temperature dependence of electrical, thermal, and structural properties of solid materials.

The material library can also accept files generated by the MatWeb material property database. This is a searchable database of over 59,000 material data sheets, including property information on thermoplastic and thermoset polymers, metals, and other engineering materials. MatWeb is a division of Automation Creations, Inc. (ACI) of Blacksburg, Virginia [www.matweb.com].

=== MEMS Module ===

Represents coupled processes in microelectromechanical and microfluidic devices. Incorporates specific multiphysics couplings for applications such as electroosmotic flow, film damping, piezoelectricity and fluis-structure interaction.

=== RF Module ===

Characterizes electromagnetic fields, currents and waves for RF, microwave, optical and other high-frequency devices. Allows for extensive post-processing such as S-parameter computations and far-field analyses.

=== Structural Mechanics Module ===

Performs classical stress-strain analysis with full multiphysics capabilities. Comprises non-linear material models, large deformation and contact abilities; all able to be freely coupled to other physics.
