new to CFD and have a simple question about models
I am a 2nd year student at university studying engineering. I have absolutely no formal training or experience with CFD yet but I am interested in the aerodynamics field. My question is why is it common to use only half of the model for analysis? I was told that analyzing a symmetrical half of complex models reduces CPU power. Is that true? Thanks.

Two assumptions behind this: a) the flow is indeed symmetric to a given axis/plane b) your code has symmetry boundary conditions you can apply to the "cut" Hope this clears it up! Cheers! |
Thank you. This was just one of the things I have been curious about.
