Choice of planes at an angle in cfd post

kastarkas · February 23, 2017, 01:26

Hello friends,

Seeing you all after a while. Wishing a great 2017 to all (a bit late isnt it ?).

So i have a doubt, in CFX - CFD post about creation of planes.

I needed a plane , say , a YZ plane with an angle of say 5 degrees w.r.t 'Z' axis. I also need to traverse the plane along in a direction normal to the rotated plane, at different lengths.

Using plane bound i can crop the plane acoording to my requirement. But if i specify the X distance to traverse the plane, it would not move in a direction normal to the YZ plane.

I tried translation, plane is traversing in its normal direction only, but it is getting replicated and not cropping down to my cross section of interest as i move it.

I tried 3 point method also, the same thing happened.

How can i resolve this ?

Regards

Hi

If you can post a picture of what do you want to do it would be a bit better.

However if you have to generate several planes, I would use point and normal and get, for each plane you want to generate point and normal in DM/SC or your cad tool. Honestly I don't have good experience trying to manipulate planes in CFD post, I just prefer to have all the info I need available from CAD software and implement these in CFD Post.

Thank you for the reply. Sorry for a late one.
Ok. I tried to do with points and normal, but still couldn't resolve it.
But I somehow managed to get a plane that is close enough...
