Current engineering is found in a state of evolution and very advanced structured in relation to the middle twentieth century engineering. Using complex work tools based on sophisticated mathematical models initiated the emergence of the simulators. These huge volume of calculation and comprehension programs is based on traditional assumptions and experience of researchers from different scientific fields. The programs are used by a specialist team or individuals from narrow work areas. These tools are often "black boxes" for users. This presents dangers of misuse of programs and breaking of...
