Partial cut plane

Please login with a confirmed email address before reporting spam

Hello,

1) I have a 3D geometry. It is a pipe and I would like to do 2D cut plane. In my case I want to do partially. It means that I do not want to cut for all diameter (between boundaries) of pipe but for example 1/3 of diameter. Actually I need to take maximum velocity from desired area of pipe. Is it possible somehow? If not is it possible to add a function that will take maximum velocity from desired area?

2) I want also to change angle of cut plane by +/- 5 degrees. Can anybody explain me the plane entry method: point and normal? Is it a point and a perpendicular normal vector to the cutting plain? Am I right?

Thanks in advance.

Hi

I have no direct ansver, but "my way" is either t use coupling operators, or easier often, to split up your domain into smaller domains with boundaries along the directions you want to integrate over (a tube of flud flowing can be made geoemtrically of several concentric domains, This adds a few internal continuation boundaries bat eases the selection of sub domains/ boundaries.

Pls not that searchin for a maximum is a long process in a highly looped solver sequence

Good luck

Thank you for replay. But I think I will go in direction Matlab. I am trying to figure out, how I can extract calculated parameters. Especially what interesting me the most, velocity and coordinates. If I will have it I can write a simple script in Matlab that will exclude non desired velocity. I think it is the best solution.
