ROTation
(OP)
Hi all,
The DOF ROT in shell elements makes the node to rotate but i do not get the unit of that. If I have to rotate a disc at 5000rpm then what i have to do??? Any helps please...
Thanks, Thiru.

RE: ROTation
the unit of DOF ROT is a Radian or Degree that depended what unit selected in Parameters>Angular units menu (in ANSYS 7.0).
the value 5000RPM is a Time depended value and should solve that in transition solver
RE: ROTation
OMEGA, OMEGX, OMEGY, OMEGZ, KSPIN
or, in the GUI, go to one of the following as appropriate:
Main Menu>Preprocessor>Loads>Define Loads>Apply>Structural>Other>Angular Velocity
Main Menu>Preprocessor>Loads>Define Loads>Delete>Structural>Other>Angular Velocity
Main Menu>Solution>Define Loads>Apply>Structural>Other>Angular Velocity
Main Menu>Solution>Define Loads>Delete>Structural>Other>Angular Velocity
As kiavash points out, be mindful of your units system.

RE: ROTation
Thanks for the replies & drej, the angular velocity command looks appropriate if we are considering single structure (i.e. Single roller). If it is needed for 2 rollers rotating with contact between them, what has to be done? Is there any options for giving 2 velocities for different rollers???
Thanks, Thiru.
