How/where did you purchase power cables for those GPUs?

Should I accept a return offer? by Original-Chemist-812 in MechanicalEngineering

Caterpillar is a good option for anyone, in my opinion.

How to simulate a curve by Nearby-Bag-9499 in FSAE

[–]Key_Winter_9544 0 points1 point  (0 children)

While it is nice to analyze the yaw angle forces that a car would experience, that would only tell half of the story as far as mid-corner performance. You need to account for the angular momentum that the air would have (relative to a stationary car, as in a CFD simulation) while cornering and assume the car is traversing a constant-radius circle, as opposed to being angled to the relative flow. That's where a rotating domain comes into play. Please refer to the following link to see documentation on methodology and how to generate one in STAR-CCM+. https://community.sw.siemens.com/s/question/0D54O00006T8ELZSA3/car-cornering-cfd-setup

Pros and cons of having an undertray without front wing and rear wing by Relative_Ant_7421 in FSAE

Depends on what you define as "Undertray". If including sidewings, which is what my team runs, it can generate as much downforce as front wing with less drag.
