Introduction  
The System Dynamics software TRUE, developed by TrueWorld System Dynamics, is a tool for modeling, simulating, analyzing and optimizing multidomain dynamic applications 

TRUE software : applications  TRUE software : principle 
Operation and strategic research, decisionmaking Conflict management dependent on scarce resources Risk Management dependent on Earth resources Macroeconomics, Microeconomics, Econometrics, Econophysic, Systemic Mathematics, traditional physics, Numerical Analysis, Statistics Relative Mechanics, Social Mathematics Accounting Medicine Statistical process control (SPC) Constraint Satisfaction Problems (CSP) Constraint programming (PPC) 4D virtual prototyping Robotics Multibody Dynamics Simulation (MDS) 
System dynamics modeling in discrete and continuous time (Euler) Transparent and implied mathematical modeling Coupled nonlinear differential equations of order n^{n} TRUE preserves the stocks integrity Dynamic optimization, feedback Algorithm for backtracking (BT Backtrack, loop back, dynamic backtracking) Wysiwyg graphic interface Graphical modeling, 3D modeler, bone features Real time 3D animated viewer without postprocessing Multibody Dynamics Simulation Procedural Animation 
Example : strategic model  
The dynamic display of the variables (in a 2D or 3D view) allows to understand a model for the simulated period, that is more easily understandable than a list of static variables
This model is in the True package 

Example : Modern Monetary Theory  
Public analysis of alternative monetary theories Working with Steve Keen’s Circuit Model Continuous time model by Fred Decker This model is in the True package 

Example : Medicine model  
Glycemic control Imported Vensim (VensimPLE) model See more on ModelisationSvt This model is in the True package 

Example : mechanical engineering with 3D procedural animation  
The motion of a nonoffset piston connected to a crank through a connecting rod,
can be expressed through several mathematical equations See more on wikipedia Example of piston motion This model is in the True package 

3D graphic modeler  
The software True can simulate a physical model and render it through a 3D animation created with its 3D modeler
