pyLBM.elements.Cylinder_Triangle¶

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

Class Cylinder_Triangle

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 triangular section v1 : a list of the three coordinates of the second vector that defines the triangular 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

Examples

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

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

Attributes

number_of_bounds	(int) 5
center	(numpy array) the coordinates of the center of the cylinder
v0	(list of doubles) the three coordinates of the first vector that defines the base section
v1	(list of doubles) the three coordinates of the second vector that defines the base section
w	(list of doubles) the three coordinates of the vector that defines the direction of the side
label	(list of integers) the list of the label of the edge
isfluid	(boolean) True if the cylinder is added and False if the cylinder is deleted
number_of_bounds	(int) number of edges (3)

Methods

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
test_label()	test if the number of labels is equal to the number of bounds.
