## Overview

The use of simulations as part of design process is increasingly becoming a standard practice in industry and research. This is mainly because it leads to efficient design in lesser time. Due to same reason CFD (Computational Fluid Dynamics) is rapidly becoming an integral part of product development cycle. When CFD was newly invented it was just part of research laboratories. Now since the growth of commercial CFD software and more powerful computing resources, CFD has become a part of every design team in industry. The most critical obstacle toward learning CFD is the fundamental knowledge and high level of expertise in software usage. Currently among the most popular software in industry to perform CFD analysis is ANSYS FLUENT. We at LearnCAx believe that for becoming a CFD expert one must focus not only on software, but the overall ‘CFD for design’ idea. To gain expertise in CFD one must develop four basic skills or capabilities. Those are fundamental knowledge of fluid dynamics, theory of CFD, CFD software skill and lastly how to use CFD results for making design decisions. This course on CFD covers all these aspects and not just software training. Although the course involves education on CFD software suite of ANSYS FLUENT and ANSYS ICEM CFD, the end objective of the course is not just to make you an expert software user but to inculcate a thinking of how to use CFD as a design tool. For achieving this goal, more focus is given to all the advanced simulations of complex physics like heat transfer, multiphase flows and rotating machinery applications; since these are the core points which are going to develop you as industry ready CFD personal. To teach CFD skill sets the course will include variety of learning techniques like course lessons, software demos, video tutorials, quiz, practice assignments, course project and online mentoring. ## Recommended backgroundA science background is recommended for this course. One should be familiar with basic physics concepts like scalars, vectors, pressure, velocity, forces etc. The course will start with a review of fundamental concepts of fluid dynamics and heat transfer. So you do not need any pre-requisite for this course other than having an interest in CFD. No specific educational degree is necessary to take this course. CFD analysis is based on fundamental equations of fluid dynamics and heat transfer; hence participants from mechanical, chemical, civil and petroleum fields find themselves more comfortable than other background. They will also benefit more than participants from other background.
## Your LearningThe main objective of the course is to make you understand how CFD is used as a design tool. You will be learning fundamental knowledge of fluid dynamics, theory of CFD, CFD software skill and most important how CFD results are important for making design decisions. After successful completion of this course you will be able to solve the fluid flow and heat transfer problems using ANSYS FLUENT. You will be also capable of solving physics from different domains such as rotating machinery applications and multiphase flow problems. You will able to understand the importance of simulation tool and will start to solve real world problems on your own. You will be able to understand the use of CFD results for predicting product performance, optimizing the designs and validating the product behavior.

The learning section also contains short software demos whose duration is usually very small and detailed video tutorials which are not like unreal, bookish type tutorials whereas they are actually real world industry level CFD Simulations. Some of them are actually optimization studies as well. The second stage of the course is to evaluate the participant. We have designed tests and quiz at apt intervals which further develop his/her interest in the course. Lastly, our course contains a complete process of certification, where in the participant is provided with various choices of assignments to work on. The assignments are basically CFD problems, for which the participant is expected to prepare a correct CFD approach, execute the simulation, and submit a report of the simulation. After evaluating the report, the participant is provided with the LearnCAx certification. As you know, the course is delivered based on a concept of ‘online learning using video lessons accompanied with live mentoring’. Below are short descriptions of each of the features or elements of our training process :
- Mentoring through email (Unlimited) : During the course you may have queries or doubts about the course content. To resolve those queries our mentors will interact with you using email.

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.
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.
One of the most commonly used algorithms to convert the partial differential equation to algebraic equations is the Finite Volume Method.

Although this lesson covers all types of shell meshing, the prime focus will be more on surface cell sizing and triangular element meshing using patch independent method. This lesson will teach you how to generate shell mesh in ICEM CFD.
This lesson will focus on tetrahedral mesh generation. It will teach you the entire process of tetrahedral mesh generation using ICEM CFD. It is not always possible to generate hexahedral mesh for complex shapes of geometries in CFD. Hence you need to know how to generate tetrahedral mesh. By the end of this lesson you will be comfortable to generate mesh for complex CFD models which cannot be handled by hexahedral mesh.
Another important aspect of mesh generation and perhaps the most advanced, is prism mesh generation. Accurate numerical simulation of most physical phenomenon in fluids depends on capturing boundary effects by using prism mesh near surfaces.
