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 / C 0 MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=x fr=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.
