Course Syllabus

The course is divided into 15 lessons and additional content like assignment and project. Each lesson has a specific objective and is designed to satisfy the needs of subsequent lesson. It is recommended that you do not move to the next lesson until all the concepts in the lesson are well understood.

Video Lessons :

Lesson 1: Study of Fluid flows

Have you ever observed common fluid flow phenomenon around you? Have you ever wondered about the physics behind such fluid flows? Whether they can be described by using mathematics and who discovered such mathematical equations of fluid flows? Fluid flow is present everywhere. The aim of this lesson is to show you how every phenomenon around us involves fluid flow. The lesson will present a discussion on the three fundamental methods used to study fluid flow. In the end you will also understand where simulation finds its place as tool to study fluid flow and allied phenomenon. 

Lesson 2: Introduction to CFD 

Assuming that most of the participants are new to the topic of CFD, the first lesson is designed as an introduction to CFD. CFD is a distinct field of simulation sciences which is based on physics and mathematical equations. Hence our first lesson is designed in order to provide you a complete understanding of overall concept of CFD. This lesson provides the basics of Computational Fluid Dynamics (CFD) without going into details of the mathematics or numerical algorithms. By the end of this lesson you will have a clear understanding of CFD and terms like Design, Modeling, Simulation and CFD. You will also realize that CFD is very interesting and highly useful design tool.

Lesson 3: CFD Equations and Numerical Solution 

We believe that every participant of our course, who uses CFD software, should also be aware of what is happening behind the software. Behind the software there are physics equations solved using numerical methods. This lesson is design in a way that you will get a basic understanding of the generalized CFD equations and the numerical methods that are used to solve these equations. The objective of this lesson is to refresh the knowledge of mathematical equations which govern fluid flow and heat transfer and also to provide an overview of the additional equations that are solved in CFD. By the end of this lesson you will be familiar with Navier Stokes equations and the difference between exact and numerical solution of differential Equations.

Lesson 4: Fundamentals of Finite Volume method

One of the most commonly used algorithms to convert the partial differential equation to algebraic equations is the Finite Volume Method. Hence it is critical to understand the finite volume method. In this lesson we will see how the Navier Stokes equations are converted into mathematical formulations using the finite volume methods. This lesson would explain how to convert the integral form of conservation equations into linear algebraic equations, using Finite Volume Method.  By the end of this lesson you will have a clear understanding of the Finite Volume Method.

Lesson 5: ANSYS CFX GUI and Workflow

The objective of this lesson is to make you comfortable with the Graphic User Interface (GUI) and workflow of the software ANSYS CFX. Before starting to use any software you should be well familiar with the user interface, various mouse options and clicks as well panel locations and buttons. This lesson will provide you with all the knowledge required to handle CFX software user interface. By the end of this lesson you will be able to carry out basic tasks while using ANSYS CFX and also navigate through the User Interface of ANSYS CFX.

Lesson 6: CFD Workflow Demonstration using CFX

The aim of this lesson is to demonstrate you the entire workflow followed when conducting CFD analysis using CFX software. The demonstration is based on CFD simulation of flow over circular cylinder. By the end of this lesson you will be able to conceptualize your own CFD problem in CFX and also plan simulation setup stages on your own.  

Lesson 7: Domain Conditions in CFX

In CFX Pre, the physics modeling is based on concept of domains. A real world fluid flow phenomenon is converting into a CFD model by using the concept of domain. Domains are regions of space in which the equations of fluid flow or heat transfer are solved. This lesson will teach you how to conceptualize CFD domain and provide all user inputs in order to model physics inside domain.  

Lesson 8: Boundary Conditions in CFX

Boundary conditions are the most important part of CFD simulation setup. The objective of this lesson is to train you in order to decide how to provide sensible and accurate boundary conditions to a CFD problem. Boundary conditions are nothing but transfer of information from real life scenario to a virtual CFD model at the boundaries of the CFD environment. By the end of this lesson you will able to extract information from real life scenarios and transfer it to different boundary condition types in a CFD model within ANSYS CFX Pre.

Lesson 9: Interface, Source and Additional Variables

There may be scenarios where you will need to connect multiple CFD domains. In some situations you will also need to model power or heat storing components. Also in some cases you will need to create your own variables for CFD calculation. This lesson will teach you feature of CFX Pre software using which you can perform these advanced tasks. 

Lesson 10: Solver mathematics and setup

CFX Solve is a CFD solver. Which means it will use a meshed geometry and CFD equation along with user inputs to produce solution of these equations by using various algorithms and models. The objective of this lesson is to teach you how to provide different inputs to the software to solve a CFD problem. By the end of this lesson you will be familiar with overall procedure for implementing any CFD project in ANSYS CFX.

Lesson 11: CFX Solver Manager

When you perform CFD analysis using CFX software suite, you use separate software for computing solution. This is known as CFX solver manager. This lesson will teach you all aspects of solver manager, right from how to launch it till how to provide all user inputs required for calculating and exporting CFD results file from solver manager. 

Lesson 12: Results and Post processing after CFX simulation

The aim of this lesson is to teach you how to judge the quality of CFD results and represent them in a realistic and informative manner. You will learn how o extract CFD results using the software CFD Post. This is the separate post processing environment available when analyzing results obtained from CFX Solve. By the end of this lesson you will also learn to extract CFD results and apply them to improve design. 

Lesson 13: CFX Expression Language

Many times for extracting design relevant data from CFD results, the inbuilt functions or variables are not sufficient. In such cases the user has to create their own expressions or functions and represent them in the CFD model. In CFX you can do this by using the feature CFX Expression Language. This lesson will teach you how to use CFX expression language (CEL) create your own variable expressions and use them as plotting or reporting variables at different locations. 

Lesson 14: CFX Command language

An interesting feature of CFX software is the CFX command language. Using this you can design your own customize workflow or task and avoid repetitive use of GUI when performing complex simulations. Experienced users of software find this feature high useful.  This lesson will provide you a quick overview of the CFX command language. In this lesson you will learn how to bypass the CFX GUI and modify solution inputs using CCL in an efficient manner. 

Lesson 14: Transient Simulations in CFX

If you look around yourself you will find that many phenomenon’s in nature and in industry are time dependent phenomena. But for design as well as during simulation we are most of the times interested in steady state operation. But making a steady state assumption is not always feasible or correct. Some phenomenon does have to be studied as transient phenomenon. In this lesson you will learn how to carry out CFD simulation of transient phenomenon in CFX.
