Why my center of pressure is not on my aircraft
I have a fluid regime around the left half of my aircraft (as a void within the fluid regime):
The aircraft is 1.5 m long and has a wingspan of 3 meter. I have moved the CG of the aircraft to the origin. But after I put the mesh through the Fluent, Fluent tells me that my center of pressure--at y = 0--is 2 m to the x direction and 35 m to the z direction. This is so far away from my aircraft that I have no idea how it happens. Could you help me solve this problem?
