This option is used to specify the loss that happens during fluid flow through a fluid pipe element. It must be used in conjunction with the *FLUID PIPE SECTION option.
Product: Abaqus/Standard
Type: Model data
Level: Part, Part instance
Set TYPE=BLASIUS to define the friction parameters using Blasius's equation for the friction factor.
Set TYPE=CHURCHILL to define the friction parameters using Churchill's equation for the friction factor.
Set TYPE=TABULAR to define the Reynold's number-friction values in a tabular form.
Set TYPE=USER to define the connector loss parameters using user subroutine UFLUIDPIPEFRICTION.
Set this parameter equal to the Reynold's number for the flow in the pipe below which the linear formulation is used. If this parameter is omitted, the default value is 1.0.
