Hypermesh CFD Engineering Quantities varies with View Orientation

There was an error rendering this rich post.

Hi everyone, I'm getting this weird thing where the lift/drag/side forces calculated by Engineering Quantities in CFD post-processing varies based on my view orientation. I'm highlighting all of the vehicle surfaces each time, yet still getting different results. Can someone what I might be doing wrong? Thanks!

Could it be you're operating different time step output sets?

Could it be the selection of surfaces is different?

Which solver was used?

If relevant, do you mind posting a screenshot?

When I opened the log file I set timestep to "last" so I don't think there was timestep variation between samples. I used Acusolve 2024, and I made sure to hide all non-car surfaces and then select everyting visible remaining. I basically ran engineering quantities →forces , panned around a little bit, then did the same right after, and the values come out different. Let me know what you guys think, and thanks for the help! Cheers
