PARAM, GFL

Bulk Data Entry Specifies the uniform fluid damping coefficient for dynamic analyses.

Parameter Values 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 MathType@MTEF@5@5@+=feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=xfr=xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaam4qaiaac+cacaWGdbWaaSbaaSqaaiaaicdaaeqaaaaa@391F@ , by 2.0.

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

Comments

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