1. Standard system SD

Free upper end.

1.1. Data group identifier

SINGle RISEr SD

1.2. Boundary condition

ZL ALFL

  • ZL: real: Z-coordinate of lower end \(\mathrm {[L]}\)

  • ALFU: real: Angle of lower end from vertical \(\mathrm {[deg]}\)

If the lower end later in the specification is allowed to rotate freely around the Y-axis, ALFL will be dummy.

1.3. Line and line type

LINE-ID LINTYP-ID

  • LINE-ID: character(8): Line identifier

  • LINTYP-ID: character(8): Reference to line type identifier

If only 1 alphanumeric string is specified, the string is interpreted as LINTYP-ID.

 LINTYP-ID

The LINE-ID is taken as the line number (=1)

Numbering of supernodes:

  • ISNOD = 1 is lower end, (fixed)

  • ISNOD = 2 is upper end, (free)

Next data group is Line and segment specification.
