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)

Attributes

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

Methods
