Any distributed loads, fluxes, flows, and foundations specified for inactive elements are also inactive. However, unless you explicitly remove them, records of these loads are still kept and are listed in the data (.dat) file as though the elements were still present. Continuation of loads across steps is not affected by removal; on element reactivation unremoved distributed loads are also reactivated.
By default, if a distributed load is applied to an element that is being reactivated in a step, the distributed load magnitude is scaled up linearly from zero to its end-of-step value during the step. If such a load is applied with an amplitude reference, the magnitude value given by the amplitude reference is scaled again by a value that ramps from zero to one throughout the step. This scheme ensures that reactivation has a smooth effect on the solution, even in cases where a distributed load with an amplitude reference on a reactivated element is carried over from a previous step.
为了避免出错,可以考虑将remove和reactive分别建一个分析步,其上的荷载在随后的分析步中加上。 |
