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)
