AI Thread Summary
CFD, or Computational Fluid Dynamics, is a computer-based method used to predict fluid flow and its properties in various scenarios. It typically requires powerful, multi-core processors and can take from days to weeks to produce results, depending on the complexity of the model. While some users caution against running CFD analyses on personal desktops due to potential strain on RAM and processors, others argue that simpler problems can be solved on less powerful machines. Resources such as Wikipedia and CFD-Online provide valuable information for beginners. Understanding the basics of CFD is essential for those pursuing advanced studies in the field.

can u guys tell me what exactly is CFD and hit me with some usual stuff like links and videos so that i can get good at it..
thanks in advance

Why do you want to get good at something if you don't know what it is?
 
i love to get good at what i don't know,dats how i stay hunger

beside i think i m going to come across it in my post graduation
 
An Advice: Never run this CFD analysis at your home desktop. It would screw the hell out of your RAM and processor.In simple words, CFD is the use of computer to predict the flow and its properties in various situations. Those computers are mostly many core processors operating in parallel and their solvers run from day to several weeks to get results

Of course it all depends on what kind of model you're running, and how many simultaneous equations you eventually try to solve. It's perfectly fine to run CFD on any computer you see fit, but the size of the simulation you can solve will be limited by the amount of ram and hard drive space you have available.

That is simply not true. I've ran tests on my laptop. It really depends on the problem to be solved. Will you solve a multistage turbine on your desktop? No. Can you solve a 100k node problem? Sure.
 
I've written some programs in Fortran and QBasic that perform CFD analysis. I ran a program in uncompiled QBasic...it took a while to run but you can get results on a desktop or laptop. In my case it was an older laptop without much computing capacity at all. If memory serves me correctly, the output file consisted of a direction and magnitude given the length of the model we setup to run. We then plotted the data on a grid with a certain length and direction to represent what was going on.

If anybody wants scans of the program, I'd be happy to provide them.

Of course it would be quicker and easier just to run this on a real CFD software.
