Description

GFL

<Real>

Default = 0.0

GFL specifies the uniform fluid damping coefficient in the formulation of dynamics problems. To obtain the value for the parameter GFL, multiply the critical damping ration, C/C0, by 2.0.

In coupled fluid-structure models, PARAM, G is applied to structural portion and PARAM, GFL to the fluid portion.

Note:PARAM, GFL should be used to replace the GE field on Fluid Material entries (MATx) instead of PARAM, GE_MOD.
