The zone

The variables are described in The zone.

Methods of the class homard

These methods returns an instance of the class zone.

CreateZoneBox(zone_name, Xmin, Xmax, Ymin, Ymax, Zmin, Zmax) Returns an instance of the class zone of type box after its creation zone_name: the name of the zone based on a box Xmin, Xmax: min/max coordinates extrêmes along X Ymin, Ymax: min/max coordinates extrêmes along Y Zmin, Zmax: min/max coordinates extrêmes along Z

CreateZoneCylinder(zone_name, Xbase, Ybase, Zbase, Xaxe, Yaxe, Zaxe, R, H) Returns an instance of the class zone of type cylinder after its creation zone_name: the name of the zone based on a cylinder Xbase, Ybase, Zbase: coordinates of a point on the axis Xaxe, Yaxe, Zaxe: vector of the axis R: radius of the cylinder H: height of the cylinder

CreateZonePipe(zone_name, Xbase, Ybase, Zbase, Xaxe, Yaxe, Zaxe, R, H, Rint) Returns an instance of the class zone of type pipe after its creation zone_name: the name of the zone based on a pipe Xbase, Ybase, Zbase: coordinates of a point on the axis Xaxe, Yaxe, Zaxe: vector of the axis R: external radius of the pipe H: height of the pipe R: internal radius of the pipe

CreateZoneSphere(zone_name, Xcen, Ycen, Zcen, R) Returns an instance of the class zone of type sphere after its creation zone_name: the name of the zone based on a sphere Xcen, Ycen, Zcen: coordinates of the center of the sphere R: radius of the sphere

CreateZoneBox2D(zone_name, Umin, Umax, Vmin, Vmax, Orient) Returns an instance of the class zone of type rectangle after its creation zone_name: the name of the zone based on a rectangle Umin, Umax: min/max coordinates for the 1st dimension Vmin, Vmax: min/max coordinates for the 2nd dimension Orient: integer that defines the convention for the plane

CreateZoneDisk(zone_name, Ucen, Vcen, R, Orient) Returns an instance of the class zone of type disk after its creation zone_name: the name of the zone based on a full disk Ucen, Vcen: coordinates of the center of the disk R: radius of the disk Orient: integer that defines the convention for the plane

CreateZoneDiskWithHole(zone_name, Ucen, Vcen, R, Rint, Orient) Returns an instance of the class zone of type disk with a hole after its creation zone_name: the name of the zone based on a disk with a hole Ucen, Vcen: coordinates of the center of the disk R: external radius of the disk Rint: internal radius of the disk Orient: integer that defines the convention for the plane

The convention of the orientation of the plane is the same as the one that is applied in the other modules of SALOME, in particular GEOM: plane XY ; U <==> X and V <==> Y plane YZ ; U <==> Y and V <==> Z plane ZX ; U <==> Z and V <==> X

Note

The functions that define 2D zones should be used only of the whole mesh is 2D into a plane of coordinates.

GetZone(zone_name) Returns an instance of the class zone known by its name zone_name: the name of the zone

GetAllZonesName() Returns the liste of the name of all the existing zones

Methods of the class zone

GetName() Returns the name of the zone

GetType() Returns the type of the zone 2: box 3: sphere 5: cylinder 7: pipe 11, 12, 13: rectangle and orientation 1, 2 ou 3 31, 32, 33: disk and orientation 1, 2 ou 3 61, 62, 63: disk with a hole and orientation 1, 2 ou 3

GetCoords() Returns the array of the coordinates of the zone with the same order as in its definition with CreateZoneXXXX

Delete() Deletes the zone Returns an integer: 0: the destruction is done other value: problem

Example

The creation of a 3D box is done as follows:

zone_1 = homard.CreateZoneBox ("BLOC", -1., 1., -30., 40., 10.5, 20.8)

The creation of a disk in the plane XY is done as follows:

zone_2 = homard.CreateZoneDisk ("disk", 1., 3., 43.25, 1)

Warning

With the graphical input mode, if a zone is edited and if one of the dimensions is modified, all the iterations that were computed with this zone are unvalidated. In python mode, that is not true: the iterations stay as they are.
