pylbm.elements.Triangle¶

class pylbm.elements.Triangle(point, vecta, vectb, label=0, isfluid=False)¶

Class Triangle

Parameters

• point (list) – the coordinates of the first point of the triangle

• vecta (list) – the coordinates of the first vector

• vectb (list) – the coordinates of the second vector

• label (list of three integers (default [0, 0, 0])) –

• isfluid (boolean) –

  • True if the triangle is added

  • False if the triangle is deleted

Examples

the bottom half square of [0,1]x[0,1]

>>> point = [0., 0.]
>>> vecta = [1., 0.]
>>> vectb = [0., 1.]
>>> Triangle(point, vecta, vectb)
    Triangle([0 0],[0 1],[1 0]) (solid)

__init__(point, vecta, vectb, label=0, isfluid=False)¶

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

Methods

__init__(point, vecta, vectb[, label, isfluid])	Initialize self.
distance(grid, v[, dmax])	Compute the distance in the v direction between the triangle and the points defined by (x, y).
get_bounds()	return the smallest box where the triangle is.
point_inside(grid)	return a boolean array which defines if a point is inside or outside of the triangle.
test_label()	test if the number of labels is equal to the number of bounds.
