hello people im new here and i just finished a basic cfx course but still im not well versed in it
i learned cfx because it will be useful for my project work in external vehicle aerodynamics i ran into several problems while im trying to solve the model 1) in the place i learnt they thought me they tld me u have to subtract the solid model from the external domain in case of external aerodynamics then mesh it but when i try to do subract in boolean operation ( in ansys modeller) it gives me errors when i try the body operation all the surfaces are not deleted 2)it is seen that if ur going to analyse a car at particular wind speed u need certain domain measurements were can i get those formulas ? 3)how am i going to calculate the frontal are of the car which is needed for the drag calculations |
