arch_b_update

compas_tno.shapes.arch_b_update(x, y, thk, fixed, H=1.0, L=2.0, x0=0.0)[source]

Computes the sensitivities of upper and lower bounds in the x, y coordinates and thickness specified.

Parameters

  • x (list) – x-coordinates of the points

  • y (list) – y-coordinates of the points

  • thk (float) – Thickness of the arch

  • t (float) – Parameter for lower bound in nodes in the boundary

  • H (float, optional) – Height of the arch, by default 1.00

  • L (float, optional) – Span of the arch, by default 2.0

  • x0 (float, optional) – Starting coordinate of the arch , by default 0.0

Returns

b (array) – Value of the b parameter.
