Finding Rotation Points

Hi,

I’m trying to figure out if there is a way for me to find the coordinates of centre of rotation of a rotation mesh zone. I’d appreciate any help with this.

Best,
Tina

Hi @tinaalim,
You can find the center of rotation of rotating zone using the CAD software you use for CAD modelling. You can also share project link with us if you don’t know how to do it in CAD software.

hi @tinaalim,

here is some example.

X,Y,Z co ordinated at bottom side of image.

@HamzaBaig was right. please share project link. :wink:

Cheers!
Rohit.

With OnShape you just need to assign a material (any) to your geometry, select that geometry and click on small button which appears in lower right corner of the window (hovering the cursor over it will popup 'Display mass properties").



If your center of rotation is not the mass center, this is up to you to find it out.

Thinking about that :wink: (beware when I think!!!)…

I guess we could even analyze the effect of having a VAT with a rotation axis that does not run through the center of mass… But then it would likely need to be a transient sim :wink:

And then think of the FEA you could do with the CFD results…

This would allow to produce energy from mast oscillations. so FEA is a must. :hugs:
