Detailed Description

A zoneGenerator which selects the elements which are in all the zones generated by the given list of zoneGenerators.

An intersection of faceZones is oriented if any of the faceZones combined are oriented, otherwise the returned faceZone is unoriented.

Usage

Property	Description	Required	Default value
`type`	Type: intersection	yes
`name`	Name of the zone	no	zoneGenerator name
`zoneType`	Type of zone	no	all the zone types
`moveUpdate`	Switch to update after mesh motion	no	false

These options are followed by a list of any number of zoneGenerators which can either generate the zones locally or return zones from the lists of zones held by the mesh using the zoneGenerators::lookup zoneGenerator.

Each zoneGenerator returns a zoneSet containing a pointZone and/or a cellZone and/or a faceZone, the zoneGenerators::intersection operation combines each of the zone types unless the zoneType is specified in which case only the zones of that type are combined.

A cellZone named coneAnnulus containing the cells with centres inside the intersection of the predefined cone1 cellZone which is looked-up from the cellZoneList and are also inside the locally defined annulus is be generated by

        coneAnnulus
        {
            type        intersection;

            cone1;

            annulus1
            {
                type        annulus;
                zoneType    cell;

                point1      (-0.0075 0 -1);
                point2      (-0.003 0.0025 1);
                outerRadius 0.002;
                innerRadius 0.001;
            }
        }
