Mesh¶

Every model is built from nodes, the coordinates of the mesh, and elements, the node indices of each element:

from torchfem import Planar
from torchfem.mesh import rect_quad

nodes, elements = rect_quad(11, 6, 10.0, 5.0)
model = Planar(nodes, elements, material)

The torchfem.mesh module provides this pair in two ways:

• Generators create a structured mesh on a rectangle or a cube.
• Conversion turns an existing mesh into one of a different element type.

A mesh of arbitrary geometry comes from a file instead, which torchfem.io reads into a finished model.
