This page is a shared learning space for the course. It's a course diary – a place where class discussions, key points from lectures, and additional learning resources will be collected as we go along.

• After every few classes, the pages will be updated with notes and highlights so that students can revisit the classroom discussion.
• Assignments and homework will also appear here, so you can be well prepared.
• The links to reading material, case studies, and references are shared to help go deeper at your own pace.
• These are NOT course notes, but if one follows the instructions, you can have very good set of personalised notes.
• SPOILER: The learning material is not only curated for the exam prep, but also to have 360 x 360 coverage of CFD topics.
• Discuss: Use the discuss page available on main page and every sub-page to ask your queries. This will document all the discussion and it will be useful for others too.

Check in regularly – this page will grow with the course, just like your understanding of CFD will.

Instructions for Lab Sessions

The CFD lab experiments are submitted using the microsoft forms shared via the github repository.

The submission can be made only from institute email id. Any problems related to the login credentials must be resolved using the following link:

https://docs.google.com/forms/d/e/1FAIpQLSfK6UCWdWtvq206Oj-xDFk_MGigKHg5nZwYw6lDFJOQPIsALA/viewform

In addition to the submission of the ansys simulation reports and window snaps of the results, students are expected to maintain the lab record in the following order. The contents of the lab record:

• Title of the experiment.
• Background in your own words about the case, in min 5 sentences.
• Key steps of simulations, write such that, when you are revising you should be able to run the case without the manual.
• Answer the Viva questions at the end of the respective experiments in brief (2-3 sentences).
• How could one use the concepts from this experiment to solve a real-world problem?
• Which modifications to the experiment objectives and settings  could you make and still run the experiment successfully?
• Leave a page for attaching snapshots submitted at the end of semester, just in case if required.
