Rigid link between two nodes

[Deternanna]

Hi everybody,

Why am I not able to make a rigid link between the two selected nodes with the following code? I can not figure out what I am doing wrong. The nodes I collect are node number 905 and 908. Hope you can help.

# Rigid nodes
N_p = mapdl.nsel("S", "LOC", "Y", y3)

obs_x = x_max - ((math.sqrt(3)*(w/n_elem))/2)
obs_y = y3 - (math.sin(u)*(w/n_elem))

mapdl.nsel("S", "LOC", "X", obs_x)
N_r = mapdl.nsel("R", "LOC", "Y", obs_y)

mapdl.allsel(mute=True)

mapdl.cerig(N_p, N_r, "ALL")

Okay, I think the problem was that I did not add mapdl.queries.ndnext(0)

I'm not sure why mapdl.queries.ndnext(0) will solve your issue honestly.... but I'm glad that it did.

Did the N_p select return more than 1 node? That would be my assumption.
