coefficient of drag for 2D car model
2 Attachment(s)
I have to analyse a 2d car model of length(3.4m*10m) with a 0.75 radius in top and below of the front part of car(the Geometry is attached).

To calculate Cd what should I put in area in reference value section in ansys.
Attachment 19740


PS:I am folowing this paper

And it say :

A bus-shaped with 10 m in length and 3.4 m in
height is a simplified model proposed by Sanisa and Davidson (2003)
which takes the square shape at its rear end with the ground clearance
at 0.29 m.

Where did you make this model? DM ?

From Ansys Geometry only...why?

Actually I am modelling 3d vehicle model in design modeller and I am successful in making it but I am unable to create the round surface at front. So wanted to know how to put the round edges in modelling mode.
