Node numbering is inconsistent · ansys pymapdl · Discussion #3119
hello :) When I use the BEAM188 unit to calculate, the node number displayed in the eplot window is not the same as the node number when vtk=False. What is the reason? If you could discuss with me,...

I think the error comes when plotting the labels. The node IDs seems correct.

This issue seems to happen not only on element numbering, but with general geometrical entities. Here is a minimal example creating 3 keypoints and connecting the first two with a line:

from ansys.mapdl.core import launch_mapdl

# Launch MAPDL instance
mapdl = launch_mapdl()

# Enter pre-processing mode
mapdl.prep7()

# Create keypoints 3 keypoints
mapdl.k(1, 0, 0, 0)
mapdl.k(2, 1, 0, 0)
mapdl.k(3, 1, 1, 0)

# Create line connecting keypoints 1 and 2
mapdl.l(1, 2)

# Plot the geometry
mapdl.lplot(show_line_numbering=False, show_keypoint_numbering=True, color_lines=True)

The output shows keypoint 1 connected to keypoint 3 instead of 2:
