References

!!! Note This modifier must be used with LeeElementalNewmark integrator to work properly.

Syntax

modifier ElementalLee (1) (2) [(3)...]
# (1) int, unique modifier tag
# (2) double, damping ratio
# [(3)...] int, element tags

Remarks

1. If no element tag is provided, this modifier applies to all active elements. In this case, it is equivalent to a global damping model such as LeeNewmark or LeeNewmarkFull.

2. Unlike the above global damping models, damping ratio is applied to each element individually. In case of an invalid number assigned, a default one $0.02$ is used.
