COMSOL Multiphysics is described as 'Engineering, design, and finite element analysis software environment for the modeling and simulation of any physics-based system' and is an app in the education & reference category. There are more than 50 alternatives to COMSOL Multiphysics for a variety of platforms, including Windows, Linux, Mac, Web-based and Chrome OS apps. The best COMSOL Multiphysics alternative is Elmer, which is both free and Open Source. Other great apps like COMSOL Multiphysics are CAD Sketcher, SimFlow, dicehub and FEATool Multiphysics.
Elmer is an open source multiphysical simulation software mainly developed by CSC - IT Center for Science (CSC). Elmer development was started 1995 in collaboration with Finnish Universities, research institutes and industry.
CAD Sketcher is a free and open-source project looking to enhance precision workflows in Blender by bringing CAD like tools, features and usability to Blender.
SimFlow is a powerful CFD software, focused on engineering and science. It combines an intuitive user interface with the advantages of the open-source OpenFOAM® libraries in something more than a compact OpenFoam® GUI.
dicehub is a cloud-based SaaS offering on-demand fluid dynamics simulations. It features an intuitive, browser-based interface with capabilities for real-time collaboration and high-performance computing, streamlining complex simulation workflows without setup fees or licensing...
FEATool is a fully integrated multiphysics modeling and engineering simulation environment for Matlab and Octave, featuring built-in CAD and geometry tools, preprocessing and grid generation, solvers, and postprocessing and visualization.
Xcos is a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated.
OpenModelica – A Free Modelica Environment! OpenModelica is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage. Its long-term development is supported by a non-profit organization – the Open Source Modelica Consortium (OS.
Calculix is a free and open-source finite-element analysis application that uses an input format similar to Abaqus. It has an implicit and explicit solver written by Guido Dhondt and a pre- and post-processor written by Klaus Wittig.
PyDSTool is a sophisticated & integrated simulation and analysis environment for dynamical systems models of physical systems (ODEs, DAEs, maps, and hybrid systems).
SimScale offers a software that allows you to perform CFD, FEA, and Thermal simulations to your CAD model in the cloud without needing high-performance computing power.
Kratos Multiphysics (A.K.A Kratos) is a framework for building parallel multi-disciplinary simulation software. Modularity, extensibility and HPC are the main objectives. Kratos has BSD license and is written in C++ with extensive Python interface.
OpenFOAM is the leading free, open source software for CFD, owned by the OpenFOAM Foundation and distributed exclusively under the General Public Licence (GPL). The GPL gives users the freedom to modify and redistribute the software and a guarantee of continued free use, within...
