How to apply body force to a second order solid element ?
Altair EmployeeI want to apply centrifugal loading to a thick rotating disk (Body force = density *angular velocity ^2* radius). If it is first order element i can equally share the load among each nodes ( lumped body force vector for linear approx ). But it is not correct for second order elements (consistent body force vector for quadratic approx). Then what would be the correct way to apply the loading (other than sharing the loads to nodes , is there any way to apply the loading to the whole body at single step ).

Hi Ahilan,
If linear static I think there would not be significant difference when RFORCE is used for 1st order or second order.
RFORCE is applied in single step and is available as a load collector.

Ahilan,
Have you come across the tutorial on this already? “Analyse the Radial and Tangential Stresses of a Rotating Disc”
