Overview

Use of simulations as part of design process is increasingly becoming a standard practice in industry and research 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 is 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. LearnCAx already provides a CFD course based on software ANSYS Fluent. On the similar lines this course is designed to teach you CFD analysis using software ANSYS CFX.

The learning stages remain the same while using CFX. First you will learn fundamental theory related to CFD. Then you will learn how to generate mesh using software ICEM CFD. After that you will learn how to conduct CFD analysis using software CFX. When you use CFX software suite for any CFD simulation you need to use three different software tools. These are CFX Pre, CFX Solve and CFD post. CFX Pre is used for CFD model preparation, CFX Solve is used for CFD calculations and CFD post is used for extracting results. This course will teach you all the simulations steps involved in all these three software. You will also learn how to create your own customized functions and variable in order to make the modeling process efficient. 


Recommended background

A science background is recommended for this course.

Lesson 11: Volume meshing process – Prism meshing in ICEM CFD

Another important aspect of mesh generation and perhaps the most advanced, is prism mesh generation.

Lesson 20: 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 21: 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 highly 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 22: Transient Simulations in CFX

If you look around yourself you will find that many phenomenon in nature and in industry are time dependent phenomena. Simple phenomenon like a falling droplet of water is also a time dependent phenomenon. In industry also applications like tank filling or mixing physics are time dependent. But for design as well as during simulation we are most of the times interested in steady state operation. But this is not always correct or feasible. In this lesson you will learn how to carry out CFD simulation of transient phenomenon in CFX.
