Fundamentals of Physical Simulation

Description

In the course Fundamentals of Physical Simulation you will learn how to build physical models using the Engee platform.

Physical simulation in Engee is a way of simulating systems with 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 self-study tasks.

Knowledge requirements: completion of the courses Welcome to Engee and Visual Simulation.

Total course time: ~3 hours.

Course program

Introduction to physical simulation

A brief overview of the block library "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 configuration, 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 behavior of a 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 simulation

The features of multi-domain simulation 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.
