OpenModelica is described as '– A Free Modelica Environment!' and is an app in the Education & Reference category. There are more than 25 alternatives to OpenModelica for a variety of platforms, including Windows, Linux, Mac, Online / Web-based and Android. The best alternative is MATLAB. It's not free, so if you're looking for a free alternative, you could try Circuit JS or SciPy & Numpy. Other great apps like OpenModelica are Spyder (Free, Open Source), LTspice (Free), Xcos (Free, Open Source) and Circuit Simulator (CircuitJS1) (Free, Open Source).
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.
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.
20-sim is commercial modeling and simulation program for multidomain dynamic systems, which is developed by Controllab. With 20-sim models can be entered as equations, block diagrams, bond graphs and physical components.
This java applet is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage.
