pylbm.elements.Ellipsoid¶

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

Class Ellipsoid

Parameters:

centerlist

the three coordinates of the center

v1list

a vector

v2list

a vector

v3list

a vector (v1, v2, and v3 have to be orthogonal)

labellist

one integer (default [0])

isfluidboolean

• True if the ellipsoid is added

• False if the ellipsoid is deleted

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)

Methods

distance(grid, v[, dmax, normal])	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.
visualize(viewer, color[, viewlabel, scale, ...])	visualize the element
