pylbm.elements.Cylinder_Ellipse¶

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

Class Cylinder_Ellipse

Parameters

• center (a list that contains the three coordinates of the center) –

• v0 (a list of the three coordinates of the first vector that defines the circular section) –

• v1 (a list of the three coordinates of the second vector that defines the circular section) –

• w (a list of the three coordinates of the vector that defines the direction of the side) –

• label (list of three integers (default [0,0,0] for the bottom, the top and the side)) –

• isfluid (boolean) –

  • True if the cylinder is added

  • False if the cylinder is deleted

Warning

The vectors v1 and v2 have to be orthogonal.

Examples

the vertical canonical cylinder centered in (0, 0, 1/2) with radius 1

>>> center = [0., 0., 0.5]
>>> v0, v1 = [1., 0., 0.], [0., 1., 0.]
>>> w = [0., 0., 1.]
>>> Cylinder_Ellipse(center, v0, v1, w)
    Cylinder_Ellipse([0 0 0.5], [1 0 0], [0 1 0], [0 0 1]) (solid)

__init__(center, v1, v2, w, label=0, isfluid=False)¶

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

Methods

__init__(center, v1, v2, w[, label, isfluid])	Initialize self.
change_of_variables()
distance(grid, v[, dmax])	Compute the distance in the v direction between the cylinder and the points defined by (x, y, z).
get_bounds()	Get the bounds of the cylinder.
point_inside(grid)	return a boolean array which defines if a point is inside or outside of the cylinder.
test_label()	test if the number of labels is equal to the number of bounds.
