# Mesh: Tensor: Creation¶

For tensor meshes, there are some functions that can come in handy. For example, creating mesh tensors can be a bit time consuming, these can be created speedily by just giving numbers and sizes of padding. See the example below, that follows this notation:

h1 = (

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 from SimPEG import Mesh import matplotlib.pyplot as plt def run(plotIt=True): """ Mesh: Tensor: Creation ====================== For tensor meshes, there are some functions that can come in handy.

A 'N' will make the entire mesh negative, and a '0' (or a 0) will make the mesh start at zero.
