Fundamentals of Physical Modeling in Engee
Description
In the course Fundamentals of Physical Modeling in Engee you will learn how to build physical models using the Engee platform usage.
Physical modeling in Engee is a way of modeling systems from blocks corresponding to real physical objects that can be connected not only by mathematical directional connections, but also by physical two–way connections. This approach to creating physical models greatly simplifies working with systems of physical objects, because it eliminates the need to describe the model itself and the interaction between individual blocks using a system of equations.
Each section contains a theoretical part and tasks for independent implementation.
Knowledge requirements: completion of courses Welcome to Engee and Visual modeling.
Total course time: ~3 hours.
Course program
Introduction to physical modeling.
A brief overview of the library of blocks "Physical Modeling", ports and physical variables is given. As an example, the construction of a model of a double spring damper is studied.
Construction of physical models.
The basic principles of constructing physical models are studied: a block of solver settings, reference points, sensors and initial values of variables. The construction of models of an RC chain and a wheel rotating with friction is considered.
The study of physical signals.
The models in which the graying of the system is determined by external influence are studied: a model of an RC circuit with a constant voltage source and a model of a rotating wheel with external torque.
Initial values in physical models.
Target initial values of parameters of physical blocks are studied. The influence of the target initial values on the behavior of the model is illustrated by the example of a rotational mechanical model with two inertial elements and a gearbox.
Multi-domain modeling.
The features of multi-domain modeling in Engee are studied. As an example, the construction of a hydroelectric power plant model is considered: first, an electromechanical system is built, then a hydraulic system, and finally these systems are combined into a common physical network.
Final project: Electronic valve.
In this section, you will apply the knowledge gained to build a model of an electronic valve that controls the fluid supply.
