Last updated: July 2020. 

Complete CFD Course to teach you CFD from A-Z. Specially designed for students who have no prior knowledge of any CFD software. We will teach you from scratch and work through to understand all important commands and concepts to understand CFD and it application to sample problems.

There are many lectures available as preview (free) and based on them decided yourself about the quality of your CFD learning. I would be very much happy to see you on this course.

What you will get in this course: 

 1. Complete guidance of using commercial CFD codes such as Fluent, CFX, ICEMCFD, Ansys Meshing, Designmodeler and Ansys Workbench.   

2. How to define problem, create geometry, clean and prepare geometry, hexa and tetra mesh generation in ICEMCFD and Ansys Meshing, problem setup in CFX Pre or Fluent, problem solution in both CFX and Fluent solver, Post processing Fluent and CFD Post.   

3. Teach you that how to check mesh independence in order to make the CFD results error free due to common mistakes during CFD simulation. 

4. Enable you to compare results with experimental data to access the results accuracy and quality. 

5. Finally we teach you that how to conclude the results and how to discuss results in accordance with physics of problem. Which is needed when you are writing your project report, thesis report or research paper for conference of journal. 

6. New section on mixing of two fluids with extensive post processing is added on Feb 05, 2020. In this section I have used ANSYS 2019 R3 and made very extensive post processing including mesh independence. This problem is solved inside workbench completely. 

7. New section on double contraction pipe with 90 degs bend is added on July 12, 2020. Here you will learn Hexa meshing (Multizone) of complex geometry with solution in Fluent and Post processing in CFD-Post.
