pylbm.elements.Ellipsoid

class pylbm.elements.Ellipsoid(center, v1, v2, v3, label=0, isfluid=False)

Class Ellipsoid

Parameters

  • label (list of one integer (default [0])) –

  • isfluid (boolean) –

    • True if the ellipsoid is added

Examples

the ellipsoid centered in (0, 0, 0) with v1=[3,0,0], v2=[0,2,0], and v3=[0,0,1]

>>> center = [0., 0., 0.]
>>> v1, v2, v3 = [3,0,0], [0,2,0], [0,0,1]
>>> Ellipsoid(center, v1, v2, v3)
    Ellipsoid([0 0 0], [3 0 0], [0 2 0], [0 0 1]) (solid)
__init__(center, v1, v2, v3, label=0, isfluid=False)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(center, v1, v2, v3[, label, isfluid])

Initialize self.

distance(grid, v[, dmax])

Compute the distance in the v direction between the ellipsoid and the points defined by (x, y, z).

get_bounds()

Get the bounds of the ellipsoid.

point_inside(grid)

return a boolean array which defines if a point is inside or outside of the ellipsoid.

test_label()

test if the number of labels is equal to the number of bounds.
