How to angle coordinate frames?

dccfd · April 23, 2017, 07:51

Hi all,

I have created two coordinate frames around a hub which is slightly angled but when I assign these frames they both point vertically, which I am not sure how to change. I have tried looking at Eulers rotation angles but I am not sure if I am looking in the right direction to solve this problem. I have attached a picture for a visual representation.

I am quite new to Ansys so I am learning as I go, but if someone could point me in the right direction on how to get these so they are in the right orientation, then that would be fantastic.

Thanks!

When I look at those green vectors I see one is leaning left by a few pixels and the other is leaning right by a few pixels. So they appear to be off parallel by a small amount. Isn't this what you intended?

Thanks for replying, but they should be on a 5 degree angle and parallel, I am not sure why they are in different directions. Is there a way I can manually set the direction?

The perspective view in CFD-Post does distort angles a very small amount. You are probably seeing that distortion.
