1. Element angle time series from time domain analysis

1.1. Data group identifier, one input line

ELMAngle TIME SERIes        Plot

1.2. Output options, one input line

IOP IT1 NTS NNELC

  • IOP: integer: Code for type of output

    • IOP=1: Time series

    • IOP=2: Time series statistics

    • IOP=3: Spectral analysis

  • IT1: integer: First stored time step to be included

  • NTS: integer: Number of stored time steps to be included (from IT1).

    • A large number includes the remaining time steps

  • NNELC: integer: No. of pairs of input lines used for element specification

Two of the subsequent input lines (Code for element specification and either Global or vessel axis and element specification or Element pair specification) given NNELC times.

1.3. Code for element specification

IRELCO

  • IRELCO: integer: Code for type of output

    • IRELCO=0: Angle between fixed global axis and one specified element

    • IRELCO=1: Angle between support vessel coordinate axis and one specified element

    • IRELCO=2: Angle between two elements

1.4. Global or vessel axis and element specification

This input line is given only for IRELCO=0 or 1.

IAXIS IVES LINE-ID ISEG IELM HEAD

  • IAXIS: integer: Code for axis

    • IAXIS=1: x-axis

    • IAXIS=2: y-axis

    • IAXIS=3: z-axis

  • IVES: integer, default: 1: Vessel number if IRELCO=1 else dummy

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

  • ISEG: integer: Segment number

  • IELM: integer: Element number

  • HEAD: integer: Vessel heading in final static position if IRECLCO=1, else dummy \(\mathrm {[deg]}\)

The angle output is between 0 and 180 degrees. If the element direction (from end 1 to end 2) is along the specified axis, the relative angle is 0. Otherwise, if the element direction is along the negative axis direction, the angle is 180 degrees. The element direction is calculated as the direction along the secant from local end no 1 to local end no 2 (i.e. local element x-axis).

1.5. Element pair specification

This input line is given only for IRELCO=2.

LINE-ID1 ISEG1 IELM1 LINE-ID2 ISEG2 IELM2

  • LINE-ID1: character(8): Specification of first element

  • ISEG1: integer:

  • IELM1: integer:

  • LINE-ID2: character(8): Specification of second element

  • ISEG2: integer:

  • IELM2: integer:

The angle output is between 0 and 180 degrees. If the element direction (from end 1 to end 2) is along the specified axis, the relative angle is 0. Otherwise, if the element direction is along the negative axis direction, the angle is 180 degrees. The element direction is calculated as the direction along the secant from local end no 1 to local end no 2 (i.e. local element x-axis).
