Request a result on a specific path of coordinates

This example shows how to use the legacy PyDPF-Post API to request a result on a specific path of coordinates.

Perform required imports

Perform required imports. This example uses a supplied file that you can get by importing the DPF examples package.

from ansys.dpf import post
from ansys.dpf.post import examples

Get Solution object

Get the Solution object. This example loads a simple file supplied with PyDPF-Post.

solution = post.load_solution(examples.static_rst)

Create coordinates array to request result on

coordinates = [[0.024, 0.03, 0.003]]
for i in range(1, 51):
    coord_copy = coordinates[0].copy()
    coord_copy[1] = coord_copy[0] + i * 0.001
    coordinates.append(coord_copy)

Create DpfPath object

Create a DpfPath object.

path = post.create_path_on_coordinates(coordinates=coordinates)

Request result on this path

stress = solution.stress(path=path)

Plot result

stress_eqv = stress.von_mises
stress_eqv.plot_contour()
