Cylindrical Nodal Stress

Visualize the nodal stress in the radial direction. This is equivalent to setting the result coordinate system to cylindrical in MAPDL (e.g. RSYS, 1).

Download a small result file containing the corner of a thick pipe

from ansys.mapdl.reader import examples

rst = examples.download_corner_pipe()

# obtain the cylindrical_nodal_stress
nnum, stress = rst.cylindrical_nodal_stress(0)
print(stress)

# contains results for each node in following directions
# R, THETA, Z, RTHETA, THETAZ, and RZ
print(stress.shape)
