Getting Correct Drag Coefficient
I am trying to get a drag coefficient. For some reason, I am getting a number that doesn't really make sense. I will place the pictures of what I did.
I imported the geometry, created an enclosure, and suppressed the geometry. I suppressed the geometry in an effort to make "walls" out of the geometry.
I added a surface area report definition. I selected the option enclosure_enclosure. I believe it did select the right thing to calculate for drag.
Once again I added another report definition, I added a drag coefficient. I selected the enclosure_enclosure option. It, however, did not select the geometry like the surface area report. I'm not sure if this is right or wrong.
These are the calculation parameters I put in.
I generated vectors. I believe that the velocity vectors makes sense.
Here are the results. The only number that makes sense is the surface area. I found the surface area from Autodesk Inventor. The original number is in in^2, but a conversion was made and it verifies that the surface area is correct.
I used omni calculator to check the results.
This confirmed that the numbers dont make sense.
What can I do to fix this? This would be much appreciated.
