VisSim is described as 'Visual language for modeling and simulating nonlinear dynamic systems. With 9 integration methods, 4 optimization methods and over 200 vector and scalar block functions' and is an app. There are more than 10 alternatives to VisSim for a variety of platforms, including Windows, Linux, Mac, Web-based and BSD apps. The best VisSim alternative is GNU Octave, which is both free and Open Source. Other great apps like VisSim are MATLAB, SageMath, Mathematica and SciPy.
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.
Open-source software for mathematical modeling, nonlinear equations, and optimization problems, supporting dynamic systems and large-scale models, with both command-line and graphical interfaces, specialized modeling language, and advanced solver architecture.
Wolfram SystemModeler, developed by Wolfram MathCore, is a platform for engineering as well as life-science modeling and simulation based on the Modelica language.
With YAKINDU Statechart Tools, you can easily create complex systems in a visual way. Simulate and test your system’s behavior already while you are modeling.
Caedium (formerly SymLab) and its add-ons combine to form an easy-to-use Computational Fluid Dynamics (CFD) software system to help you assess the performance of your 3D models.
EMSO simulator is an equation-oriented process simulator with a graphical interface for modeling complex dynamic or steady-state processes. It is CAPE-OPEN compliant. EMSO stands for Environment for Modeling, Simulation, and Optimization.
The General Algebraic Modeling System (GAMS) is a high-level modeling system for mathematical optimization. GAMS is designed for modeling and solving linear, nonlinear, and mixed-integer optimization problems.
This software provides a graphical user interface (GUI) for designing and simulating algorithms and systems in digital signal processing (DSP) and digital communications.
CuPy is an open-source array library for GPU-accelerated computing with Python. CuPy utilizes CUDA Toolkit libraries including cuBLAS, cuRAND, cuSOLVER, cuSPARSE, cuFFT, cuDNN and NCCL to make full use of the GPU architecture.
StochSD (Stochastic System Dynamics) is a System Dynamics simulation software with focus on stochastics. It is a form of Continuous System Simulation (CSS) that in addition to model and simulate continuous flows between compartments, can handle transitions of discrete entities.
