AC location and Flow.edf issues

[ptc-15535]

What is the AC location on the tail sizing spreadsheet?? We are also having problems with flow.edf, we have done the fix from the video and are still having issues. When we suppress the wing that came with the project we are able to run Flow but if we don't suppress it we get an error saying "there is no fluid volume in the project. Please check geometry or boundary conditions." Any ideas????

We have figured out what AC location is, it is Aerodynamic Center. We still need help with the Flow.edf problem.

The ACwx is distance from the nose of the aircraft to the 1/4 chord of the MAC for the wing in the X direction. Likewise AChx is the the distance from the nose of the aircraft in the X direction to the 1/4 chord of the MAC of the horizontal tail, and ACvx for the vertical tail. The Leading Edge and Trailing edge can be determined by the rwdc.exe program. The values above can be taken as the L.E. of the MAC plus 0.25 of the MAC chord length minus the fuselage station of the nose of the aircraft.
