The best free alternative to SimFlow is OpenFOAM, which is also Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to SimFlow and 14 is free so hopefully you can find a suitable replacement. Other interesting free alternatives to SimFlow are FEATool Multiphysics, Code_Aster, Code_Saturne and KRATOS Multiphysics.
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...
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.
Code_Saturne solves the Navier-Stokes equations for 2D, 2D-axisymmetric and 3D flows, steady or unsteady, laminar or turbulent, incompressible or weakly dilatable, isothermal or not, with scalars transport if required.
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.
CFDTool™ (https://www.cfdtool.com) is a fully integrated and dedicated MATLAB® Computational Fluid Dynamics (CFD) Toolbox for modeling and simulation of fluid flows with coupled heat transfer.
Code_Aster is a free software for numerical simulation in structural mechanics. It is a general software for simulation in mechanics and calculation of structures.
The program package FEATFLOW is both a user oriented as well as a general purpose subroutine system for the numerical solution of the incompressible Navier-Stokes equations in two and three space dimensions.
CFD - Laminar or turbulent fluid dynamics models can be selected depending on the fluid flow Reynolds number. Both steady-state and transient solvers are available. Rotating, single and multiphase flows can be analyzed.
Powerful application for performing fluid flow and heat transfer simulations in MATLAB ® making CFD analysis more accessible than ever. Our Toolbox is compatible with other MATLAB® toolboxes and external software.
