Rectangular2D Class

class plask.mesh.Rectangular2D(axis0, axis1, ordering='01')
class plask.mesh.Rectangular2D(geometry, ordering='01')
class plask.mesh.Rectangular2D(ordering='01')

Two-dimensional mesh

create empty mesh

create mesh with axes supplied as sequences of numbers

create coarse mesh based on bounding boxes of geometry objects

ordering can be either ‘01’, ‘10’ and specifies ordering of the mesh points (last index changing fastest).

Subclasses
