Effect of Vent Ratio on Drag Coefficient

I’m trying to find the effect of varying the diameter of the vent in a round parachute on the drag coefficient. How do I achieve this in Simscale? Also, is there any existing projects that address the same question or have a similar purpose?

Hi prithika2006,

thanks for reaching out to us.
Please have a look at this public project which you could use for the generated setup.

However, a few improvements i Would recommend are:
Create the external flow Volume using the Edit in CAD Mode

Next I would extend the Flow Volume a bit further:

Lastly I would use the quarter symmetry for fast simulation runs.
