Assignment 1

1. GT Suite is multiphysics CAE system simulation software. Modules available in GT-suite are:

Flow: There are several components based on which the flow propagates. This medium helps in delivering the required matter to the mechanical components. The necessary parameters are tuned based on the medium we emphasise.

Mechanical: In this module we have all the components for transmission. The parameters size, shape and the required mechanisms are altered for simulating.

Thermal: Essential components for heat transfer are needed to be imported for running our system effectively and efficiently.

Electromagnetic: Electric and magnetic components are needed for transmitting and receiving signals, with need for charging and storing energy through essential devices are modelled here.

Control: Sensors and detectors are used to measure the output performance of the product being controlled, these measurements are used to provide corrective feedback to help and achieve desired performance.

2. Time control flag:

• It is used for denoting the simulation duration and also the variables for controlling the time.
• The events can either be periodic (requires tracking based on varying angles) or continuous (no tracking).
• The simulation time can be expressed either in cycles or in seconds based on our needs.

Time step and solution control:

• The numerical parameters for the explict and implicit solver can be defined in this process.

Integrator/solver type:

• This is used in time marching of ODE's which is present in library.
