Principle of Physical Modeling • Basic idea: use physics to model system dynamics ¾balance equations and constitutive relations 9e.g. Newton’s laws, Kirchhoff’s laws etc. ¾requires detailed knowledge about physics, brings much insight • Naturally done in continuous-time, leads to ODEs (Ordinary Differential Equations) or
`Altogether the book gives a comprehensive introduction to physical modelling and the new language Modelica and can be recommended to engineers and scientists who have to create or use models of physical systems.
21 Αυγ 2016 · With basic programming skills, you can create models for a wide range of physical systems. My goal is to help you develop these skills in a way you can apply immediately to real-world problems. This book presents the entire modeling process, including model selection, analysis, simulation, and validation.
This manual is intended for a hands-on introductory course in computer simu-lations of physical systems, using the Python programming language. The goals of the course are as follows: Learn enough of the Python language and the VPython and matplotlib graph- ics packages to write programs that do numerical calculations with graphical output;
By translating physical systems into mathematical language, models provide a structured way to understand, predict, and manipulate the behaviors of these systems.
In summary, real life phenomena together with physical and other relevant laws, observations and experiments lead to mathematical models (which could be ODE). One would like to do mathematical analysis and computations of solutions of these models to simulate the behaviour of these physical phenomena for better understanding.
Physical modeling is a way of modeling and simulating systems that consist of real physical components. It employs a physical network approach, where Simscape™ blocks correspond to physical elements, such as pumps, motors, and op-amps.
