Course "Fundamentals of Physical Modelling in Engee"
Description
In the Foundations of Physics Modelling in Engee course, you will learn how to build physics models with usage of the Engee platform.
Physical modelling in Engee is a way of modelling systems from blocks corresponding to real physical objects, which can be connected not only by mathematical directed links, but also by physical two-way links. This approach to creating physical models greatly simplifies work with systems of physical objects because it eliminates the need to describe the model itself and the interactions between individual blocks using a system of equations.
Each section contains a theoretical part and tasks for independent fulfilment.
Knowledge requirements: Completion of the courses Welcome to Engee course and Visual Modelling Course.
Total course time: ~3 hours.
Course Programme
Introduction to physical modelling.
A brief overview of the Physical Modelling block library, ports and physical variables is given. As an example, the construction of a double spring damper model is studied.
Building physical models.
The basic principles of building physical models are studied: solver settings block, reference points, sensors and initial values of variables. The construction of RC-chain and friction wheel models is considered.
The study of physical signals.
Models in which the seating of the system is determined by an external influence are studied: a model of RC-chain with a constant voltage source and a model of a rotating wheel with an external torque.
Initial values in physical models.
Target initial values of parameters of physical blocks are studied. The influence of target initial values on the model behaviour is illustrated on the example of a rotational mechanical model with two inertial elements and a gearbox.
Multidomain modelling.
The features of multidomain modelling in Engee are studied. As an example, the construction of a model of a hydroelectric power plant is considered: first the electromechanical system is built, then the hydraulic system, and finally these systems are combined into a common physical network.
Final project: Electronic valve.
In this section, you will apply what you have learned to build a model of an electronic valve that controls a fluid supply.
