`structure scale-rotational-mass`

command

Syntax

- structure scale-rotational-mass <b >
This value applies to dynamic analysis only. If set to off, then the rotational degree-of-freedom masses are computed using a sphere with a volume equal to that contributed by elements using the node. This is described as fully dynamic mode in Mass Scaling. If set to on, then the rotational degree-of-freedom masses are scaled based on rotational stiffnesses. This is described as partially dynamic mode in the structural element section Mass Scaling.
