Notes

The OCZONE command specifies the type of ocean zone data to follow (component, Z-level, or internal pipes associated with an external pipe). An ocean zone is a local space where you can override global ocean-loading parameters.

Names specified for ZoneName, CompNameInt, and CompNameExt can consist of up to 32 alphanumeric characters. The name cannot contain punctuation, special characters, or spaces.

For Zonetype = COMP, the zone is defined by a component. Only the elements in the component are affected by the local parameters. A partial component can be defined as the zone via the Z input on the OCTABLE command.

For Zonetype = ZLOC, the zone is defined by Z levels. Structural elements (such as BEAM188, BEAM189, PIPE288, PIPE289, and LINK180) in the Z levels are included in the zone.

For Zonetype = PIP, the zone is prepared for a special configuration of pipes. It associates an internal pipe or pipes with an external pipe to remove the hydrodynamic effect on the internal pipe. Only hydrostatic pressure is applied on the internal pipe.

This command is also valid in PREP7.

Issue this command before defining your ocean load data (OCDATA or OCTABLE). Define components before defining a component-type or a pipe-type zone (OCZONE,COMP or OCZONE,PIP, respectively).
