The WPON and WPOF data records are used instead of ZRWS/ZRON/ZROF to output incident or disturbed wave height at a node. These data records are only applicable to time domain analyses which include wave frequency motions. The disturbed wave height output is only available for Aqwa-Naut. If the ALLM data record is present, the vertical velocity and acceleration of incident waves are also output.
These data records are input before/after the particular NODE data records which then have a slightly different configuration, as described below:

(1), (2), and (3) parameter inputs of the WPON data record are used to define the disturbed wave height output. (1) and (2) work together to decide the structure that outputs the disturbed wave height at the nodes associated with it. If (3) is given but (1) and (2) are not given, the disturbed wave height results are output for all the nodes defined in the following NODE data records:
(1) This structure number corresponds to one of the structures defined in Element Topology - ELM* (Data Category 2). If it is not input or input as ‘0’, the structure number defined in (2) is ignored as well.
(2) It is the structure sequence number in the .PAG file which corresponds to the current structure sequence number defined in (1). It is only required when (1) is input and not input as ‘0’.
(3) The file name with the .PAG extension imports the database of pressure at the mean free surface grids, which is used to calculate and output the disturbed wave height. If it is not input, the incident wave height is output for the nodes defined in the following NODE data records.
Note: When the structure sequence number in the current analysis (1) is not defined for the disturbed wave height output, the total number of structures in the .PAG file must be the same as that of the current analysis model.
Note: WPON and WPOF act as switches during the input of the NODE data records and have the function of switching the wave parameters option ON and OFF.

| (1) This structure number must correspond to one of the structures defined in Element Topology - ELM* (Data Category 2) . Structure number 0 (a fixed node) is illegal in this field. |
| (2) This is the node number at which output of the wave parameters is requested. The position of this node on the structure (1) must be defined in Node Number and Coordinates (Data Category 1). |
| (3)-(4) These fields are optional. They are used to specify that the node defined in (1) and (2) is fixed. If used, the structure number must be 0 and the node number (4) must be the same as node (2). |
