### Centrifugal distributed loading

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.
