1. FLUID - Specification of internal fluid flow

1.1. Data group identifier

NEW COMPonent FLUId

1.2. Component type number

CMPTYP-ID
  • CMPTYP-ID: character(8): Component type identifier

1.3. Fluid flow characteristics

RHOI VVELI PRESSI DPRESS IDIR
  • RHOI: real: Density \([\mathrm {M/L^3}]\)

  • VVELI: real: Volume velocity \([\mathrm {L^3/T}]\)

  • PRESSI: real: Pressure at fluid inlet end \([\mathrm {F/L^2}]\)

  • DPRESS: real: Pressure drop \([\mathrm {F/L^3}]\)

  • IDIR: integer, default: 1: Flow direction code

    • 1: Inlet at supernode end 1 of the line

    • 2: Inlet at supernode end 2 of the line

The pressure drop is assumed to be uniform over the line length. For further clarification of pressure definition, confer Theory Manual.

In this version only RHOI is used to calculate weight and mass for static and dynamic analysis. The other parameters are used for calculating wall force (flange force) only depending on output option (OUTMOD)
