A computer model is a mathematical model which, due to its complexity and / or the high number of degrees of freedom, can only be evaluated with a computer. Evaluation usually means the calculation of an approximate solution using numerical methods ( computer simulation ), but it can also be the graphic representation ( visualization ) of a complex system, e.g. B. in architecture (virtual building model, see computer models ). There are already different simulation software available for evaluating computer models, e.g. B. OpenFOAM for continuum mechanical problems.

In most cases, computer models capture both aspects of evaluation and visualization : On the one hand, not only are the mathematical relationships complex, but the results of the simulation also require tools from computer graphics . On the other hand, simulation software is often built into computer models that were originally only used for graphical representation; so z. For example, more and more building simulations are carried out on building models in architecture (calculation of static and dynamic load situations, mass determination, exposure situation).

Well-known and important examples are:

• Atmospheric models as a basis for weather forecasting
• Climate models for predicting climate change
• Agent-based models for simulating social interactions in artificial intelligence
