What is Modelling?

This blog is all about system dynamics modelling and simulation applied in the engineering field, especially mechanical, electrical, and civil engineering. It is concerned about the theories and applications of physics based modelling, for example analytical approaches, finite element method, etc., numerical methods to solve problems, and so forth. Nevertheless, the concept may be applied to other research arenas as well. Now-a-days, modelling is the very first step in making an object to be used in some applications as this would provide valuable insight in the design as well as its physical characteristics.

Modelling and Simulation Examples
Modelling may be classified broadly into two categories: signal based and model based approach. Signal based method is a well-established technique that has been implemented for a long time. This method has simplicity as it only depends on the system outputs for fault diagnosis while treating the plant as black box. On contrary, model based approach creates a model of the system with physical parameters where any change in the model can easily be observed by tuning those parameters. Model based approach may be classified into two categories - data driven and physics based modelling.

Designed in SOLIDWORKS

In this blog, we will see mostly physics based modelling examples using various methods. There are also demonstrations of various software, such as, MATLAB, Mathematica, SolidWorks, ABAQUS, and so on. We will also discuss some basics of other modelling methods.
