sailfish.mesh.PlanarCartesian2DMesh

class sailfish.mesh.PlanarCartesian2DMesh(x0: float = 0.0, y0: float = 0.0, x1: float = 1.0, y1: float = 1.0, ni: int = 1000, nj: int = 1000)

Bases: NamedTuple

A 2D mesh with rectangular binning.

The length of the domain is related to height by an aspect ratio. The minimum demarcations along an axis is also variable allowing for non-square meshing if need be.

count(value, /)

Return number of occurrences of value.

index(value, start=0, stop=9223372036854775807, /)

Return first index of value.

Raises ValueError if the value is not present.

ni: int

Alias for field number 4

nj: int

Alias for field number 5

sub_mesh(di, dj)

Return a new mesh that is a subset of this one.

The arguments di and dj are tuples, containing the lower and upper index range on this mesh.

vertex_coordinates(i, j)

Return the position of the lower-left corner of zone (i, j).

x0: float
