#$ MISCEL_1

Contains the material ID (RRMAT) for each element in the input file, the nozzle data (VFLEX), the hanger data, and the execution options.

Material ID

Contains the material ID number in the first array for each element in the input file. Use the FORTRAN format (2X, 6G13.6).

The RRMAT array is dimensioned (N1). The material IDs range from 1 to 699 (See the User’s Guide for details).

The number of lines required to write the RRMAT array in the neutral file is determined by the following FORTRAN routine:

NLINES = NUMELT / 6

IF(MOD(NUMELT,6).NE.0)THEN
NLINES = NLINES + 1

ENDIF

Hangers

Describes the spring hangers in the input file. Some of the hanger data listed below represents uninitialized data. In the instances where this uninitialized data represent infinite values (such as maximum travel limit and available space), it is reported here as 9999.99.

The next line contains values for the following parameters in FORTRAN format (2X, I13, 5G13.6):

  • IDFTABLE is the default hanger table.

  • DEFVAR is the default for allowed load variation.

  • DEFRIG is the default for rigid support displacement criteria.

  • DEFMXTRAVEL is the default for maximum allowed travel.

  • DEFSHTSPR is the default for allowing short range springs (0=no 1=yes).

  • DEFMUL is the default multi-load case design option.

The next line contains values for the following parameters in the FORTRAN format (2X, 5I13):

  • IDFOPER is the default number of hanger design operating cases (always 1).

  • IACTCLD is the default cold load calculation switch (0=no, 1=yes).

  • IHGRLDS is the number of hanger operating loads (0 -3).

  • IACTUAL is the load case defining actual cold loads.

  • IMULTIOPTS is the multi-load case design option (1-7).

An array of hanger node numbers (IHGRNODE) is read and written for each hanger in the input file and is dimensioned (N5). There are seven lines in the neutral file for this data if all N5 hangers are specified. Use the FORTRAN format (2X, 6I13).

The neutral file reads and writes an 11-element array (HGRDAT) for each hanger in the input file. The HGRDAT array is dimensioned (11,N5). Each hanger in the model requires two lines in the neutral file. Use the FORTRAN format (2X, 6G13.6).

  1. Hanger stiffness

  2. Allowable load variation

  3. Rigid support displacement criteria

  4. Allowed space for hanger

  5. Cold load #1 (theoretical)

  6. Hot load #1 (initialize to 0.0)

  7. User defined operating load f/ variable springs (init to 0.0)

  8. Maximum allowed travel limit

  9. Multiple load case design option

  10. Hanger hardware weight

  11. Constant effort support load (CEFF)

Use the FORTRAN format (7X, I5, 1X, A100) to write the values of the following two items on the next two lines of the neutral file. These two items follow the hanger specifications above and the neutral file repeats the lines for each hanger defined in the Hangers Auxiliary data in the piping input.

  1. Hanger Tag

  2. Hanger GUID

The value at the beginning of each string indicates the length of the string. If the string is blank, the value is 0.

A four-element array (IHGRFREE) is read/written for each hanger in the input file. The IHGRFREE array is dimensioned ( 4,N5). Each hanger in the file requires one line in the neutral file.

Use FORTRAN format (2X, 6I13).

  1. Anchor node to be freed (#1)

  2. Anchor node to be freed (#2)

  3. d.o.f. type for #1 (1-free Y, 2-free XY, 3-free ZY, 4-free X, Y, Z, 5-free all)

  4. d.o.f. type for #2

An array (IHGRNUM) lists the number of hangers at this location for each hanger in the input file. There is one entry here for every hanger in the file. The IHGRNUM array is dimensioned (N5). There are seven lines in the neutral file for this data if all N5 hangers are specified. Use the FORTRAN format (2X, 6I13).

An array (IHGRTABLE) lists the hanger table numbers for each hanger in the input file. There is one entry here for every hanger in the file. The IHGRTABLE is dimensioned (N5). There are seven lines in the neutral file for this data if all N5 hangers are specified. Use the FORTRAN format (2X, 6I13).

An array of flags (IHGRSHORT) indicates if short range springs can be used at each hanger location. The IHGRSHORT array is dimensioned (N5). There are seven lines in the neutral file for this data. Use the FORTRAN format (2X, 6I13).

  • 0 = cannot use short range springs

  • 1 = can use short range springs

An array of connecting node numbers (IHGRCN) is available for each hanger. The IHGRCN array is dimensioned (N5). There are seven lines in the neutral file for this data if all N5 hangers are specified. Use the FORTRAN format (2X, 6I13).

Execution Options

  • Print forces on rigids and expansion joints 0=no, 1=yes

  • Print alphas & pipe props. during error checking 0=no, 1=yes

  • Activate Bourdon Pressure Effects 0, 1, or 2
