The author

    PSM++ is an object-oriented, Pascal-related simulation language. The language has a clear process/event structure and is equipped with appropriate environment. PSM++ translator generates a Pascal source code that can be run using a Pascal compiler. The actual version generates code compatible with the Borland's Delphi 5,6 or 7, personal, standard, home or professional. 

Recently, PSM++ becomes quite popular. For example, if you search for +PSM+++simulation in the Google search engine, you will get more than 500 Web pages that have links or refer to the PSM++ Simulation Software.

The following features make PSM++ the most complete and versatile simulation tool.

Efficient scheduling and event queue management.

Inheritance mechanism, that permits to add new properties to old processes without intervening the source code of processes declared earlier.

State events. Discrete and continuous objects can run concurrently. The state events can be activated by continuous objects as well as by logical conditions changed according to the model state.

The library of  PSM++ predefined processes contains various frequently used processes, e.g. a rigid body dynamics, and several helpful processes that handle graphics and show simulation results.

Program generator for ODE (Ordinary differential equations) models DIFEQ. The user can provide the model equations or use code generated by the signal flow modlue (FLOWD) or the bond graph module (BONDW). If you use FLOWD or BONDW, then the system equations as well as the PSM++ and Pascal codes are generated automatically. For models of any of these types the transient process simulation as well as frequency response (Bode and Nyquist plots) are provided.

Program generator for queuing models QMGW. This module includes graphical editor for queuing schemes, program and report generators.

Program generator for continuous processes FLOWD described by signal flow diagrams or block schemes. 

Bond Graphs editor and analyzer BONDW. This module includes a Bond graph editor and a program generator that creates source Pascal and PSM++ code for a given Bond graph model.

PSM++ Animator.
2D animator is a new, quite easy end practical, mainly for applications in manufacturing. As the animation scenario, the user can insert any bitmap, created by Paint or similar tools, or a photo of the real scenario. The model icons will move over the scenario on their predefined routes. 

VARAN: Post Mortem analyzer for stochastic (discrete and continuous) models. Shows variance, confidence intervals etc. as functions of time, particularly useful for the statistical analysis of transient processes.

Complex System Simulator CSS. Very useful for combined systems, permits model coupling. Submodels of different types (queuing, continuous, etc.) run concurrently in the same simulation program. Needs no or very little programming. Generates PSM++ source code.
