Introduction. Every day new applications appear on the Market, and sometimes their authors or developing companies  don’t call intelligent programs, but they   are actually   intelligent programs in their functions and content.  

While in the last 2-3 decades, due to successes in the development of  powerful computers  and achievements  in programming, technology of simulation of physical processes and behavior of complex systems  in our reality  has been undergoing substantial  growth. There are several examples from our present life.

• With this computerized system, surgeons  can position new knees of patient with greater accuracy than ever. When patients have perfect knee alignment, they have an improved range of motion and shorter rehabilitation times.

  Major metropolitan areas in the United States have Advanced traffic management systems (ATMS). The dispatcher monitors   can show real  images of vehicles and their positions on the roads and highways. Early warning of dangerous conditions is visually highlighted by signaling.

   

• Marine simulation as well as military air forces and commercial airlines  provide a safe and effective way of training pilots and other personnel  in a given environment  by fully simulating real equipment and real conditions.

 

In large manufacturing industries such as  machinery, automotive and aircraft industries, product design and development are now done completely by the computers. Product designers and engineers use Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE) systems to create three-dimensional geometrical objects that can be drawn, analyzed, tested and optimized. Manufacturing engineers use Computer-Aided Manufacturing (CAM) systems for process planning, control , tool design, etc.

If CAD/CAM systems were born 2-3 decades ago, CAE tools had the rapid growth and adoption at the period of the last decade. This type of tools has a number of applications in structural design, civil engineering, mechanical engineering,  electrical engineering and so on. Now we can get CAE tools for simulation of solid, fluid, electromagnetic and other physical phenomena. This growth is propelled by market pressures that demand reduced time-to-market, increased productivity and enriched  features for their products. 

To build a model of either  processes, or events, or processes with continuous or discrete events, there are needs to have  the descriptions  of all above by  text, math formulas, any kinds of graphs, matched data, etc.  and special methods of digital modeling  (simulation) with help of different types of models (2D or 3 D), such as wireframe models, solid models, surfaces models, etc., plus special tricks, needed  to graphically visualize, manipulate, and solve engineering, architectural, training and other problems.
