# Need help with numpy script

Any numpy experts?

I am trying to incorporate this as a blender script, but not sure how to do so.

Here is the script:

``````#! /usr/bin/env python
# -*- coding: utf-8 -*-
import numpy as np

# Number of nodes along the width of the strip (>= 2)
# Choose it such that we have approximately square boxes.

# Generate suitable ranges for parametrization
u_range = np.linspace(0.0, 2*np.pi, num=n, endpoint=False)
v_range = np.linspace(-0.5*width, 0.5*width, num=nw)

# Create the vertices.
nodes = []
for u in u_range:
for v in v_range:
nodes.append(np.array([x, y, v]))

# create the elements (cells)
elems = []
for i in range(n - 1):
for j in range(nw - 1):
elems.append([i*nw + j, (i + 1)*nw + j + 1, i * nw + j + 1])
elems.append([i*nw + j, (i + 1)*nw + j,     (i + 1)*nw + j + 1])
# close the geometry
for j in range(nw - 1):
elems.append([(n - 1)*nw + j, j + 1, (n - 1)*nw + j + 1])
elems.append([(n - 1)*nw + j, j, j + 1])

return np.array(nodes), np.array(elems)

if __name__ == '__main__':
import meshio
points, cells = create_mesh()
meshio.write('tube.vtu', points, {'triangle': cells})
