Rotating a part 2

[vempati]

Hi
Can any one tell me how can I rotate a component in Ansys.
I could not rotate(say 45degrees about X-axis) an imported file(IGES).I could do it when i create any thing in Ansys.
can any one help me

1. define a local coordinate system (commands: clocal/local/cs)
2. active the coordinate system (command: csys)
3. rotate nodal coordinate system into the coordinate system (command: nrotat)
4. check (commands: /psymb,ndir,1 ; nplot)

Hello

Can i do a impact analysis using Ansys.I want to apply a large force acting for small amount of time and next second no force and agin repeating the steps along.Atleast the first step.

Thanks

If you used the "defeature" option when you imported the iges file then you won't be able to modify the geometry.

If you didn't defeature, then follow the procedure given by ghx.

bhava9, I think you might need LS-DYNA to do an impact analysis.

Just for completeness, and to aid people who look at this post in the future, the way in which the above post describes how to rotate a part would not achieve what the original poster asked.

The original post was:

I am assuming that it is the COMPONENT (comprised of volumes, areas, lines, kp) which requires rotating in space by an angle of 45 degrees (say). In ghx's reply I believe he /she was confusing how to rotate a COMPONENT with how to ROTATE NODES INTO A COORDINATES SYSTEM, which is how he/she describes it appropriately. If you need to rotate a COMPONENT (geometry) please see thread569-114008. Rotating nodes is a similar approach only using a different #GEN command. Sorry to be picky, but hopefully it will aid people in the future!
