pyLBM.elements.Ellipse(center, v1, v2, label=0, isfluid=False)¶Class Ellipse
| Parameters: | center : a list that contains the two coordinates of the center v1 : a vector v2 : a second vector (v1 and v2 have to be othogonal) label : list of one integer (default [0]) isfluid : boolean
|
|---|
Examples
the ellipse centered in (0, 0) with v1=[2,0], v2=[0,1]
>>> center = [0., 0.]
>>> v1 = [2., 0.]
>>> v2 = [0., 1.]
>>> Ellipse(center, v1, v2)
Ellipse([0 0], [2 0], [0 1]) (solid)
Attributes

Methods
distance(grid, v[, dmax]) |
Compute the distance in the v direction between the ellipse and the points defined by (x, y). |
get_bounds() |
Get the bounds of the ellipse. |
point_inside(grid) |
return a boolean array which defines |
test_label() |
test if the number of labels is equal to the number of bounds. |
