A technical calculation is the reproduction of a certain reality for different purposes. We know technical simulations from different areas. For example, from teaching - a patient simulator as well as the flight simulator for training future pilots. In addition, the entertainment industry often uses simulations, for example a train simulator or driving simulator for a realistic gaming experience. There are also simulations for system analysis that are too complicated for theoretical or formulaic processing. In mechanical engineering or other similar industries, however, technical simulations are used for visual representation in computer-aided systems, for example to design and calculate prototypes.
Terminology of technical simulation
With the model in a simulation one visualizes a real system. The modeling includes on the one hand the system to be modeled and on the other hand the realization of the simulator as a simulation model. The latter is the abstraction of the modeling system (behavior, function, structure). A simulation process with a certain value (parameterization) is called a simulation experiment.
The results are interpreted and passed on to the system for simulation.
Sequence of the simulation
Usually, the load cases are simulated on the basis of 3-D models of the components with the corresponding software. The resulting (e.g. mechanical) behavior can thus be visualized directly on the computer. Necessary corrections to the geometry or the choice of materials can therefore also be made on the PC in this conceptual and thus more favourable early phase. In this way, both the manufacture of the component and the performance of experiments are initially only simulated. Once the development of the component is complete and all possible doubts have been cleared up, the real production of the prototype can usually be started with a clear conscience.
Modelling methods and application areas
Modeling methods are used to solve many problems in practice. Known areas of application of modeling are, for example, weather, traffic and climate modeling and capacity development or teamwork (Crew Resource Management, Crisis Resource Management CRM). Technical calculation also includes the treatment of phenomena selected from reality, such as thermodynamics, theoretical electrical engineering and technical mechanics.
Difficult technical products require complex considerations taking into account the interaction of all subsystems. Depending on the benefit of the overall model to be created, different phenomena including their interactions are included in the simulation (for example - electromagnet models with thermal, magnetic, electrical and geometric phenomena). The modelling of non-uniform systems is also discussed in the literature.
At present, only differential-algebraic equations are suitable as a basis for the "total system modeling" required for mathematical modeling, primarily because of the computing time. The content is therefore essentially restricted to this type of model for modelling overall systems.
