Centrifugal loading is selected by the *DLOAD card,
together with the CENTRIF label. Centrifugal loading is characterized
by its magnitude (defined as the rotational speed square
)
and two points on the rotation axes. Once selected, the rotational
speed applies to ALL elements of the structure. Thus, if centrifugal
loading is specified for one element of the structure, it is applied
to all elements in the structure by multiplying its value with the
density of the material. Consequently, the material density is
required. The parameter OP=NEW on the *DLOAD card removes all previous
distributed loads. It only takes effect for the first *DLOAD card in a
step. A buckling step always removes all previous loads.
