FEATool Multiphysics is a fully integrated physics modeling and engineering simulation environment, featuring built-in CAD and geometry tools, pre-processing and grid generation, solvers, post-processing and visualization.
Simulink® is a block diagram environment for multidomain simulation and Model-Based Design. It supports simulation, automatic code generation, and continuous test and verification of embedded systems.
United States
Xcos is a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated.
France
EU
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.
Minsky enables the simulation of models (particularly from economics) defined in terms of coupled ordinary differential equations. The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.
Australia
VisSim™ is a visual language for modeling and simulating nonlinear dynamic systems. With 9 integration methods, 4 optimization methods and over 200 vector and scalar block functions.
