I'm trying to couple the y-degree of freedom of a set of nodes using pymapdl, but the function seems to be limited to 20 points:

mapdl.cp(8, 'uy', nodes[0], *nodes[1:])

Error:

TypeError: CoupledDOF.cp() takes from 1 to 20 positional arguments but 32 were given

First of all, it doesn't make sense to me at all why there would be such a limitation implemented. Second, is there a way to work around this?

Any help is appreciated

Hi

Looks strange the CP command (see MAPDL.CP() command in pymapdl site: https://mapdl.docs.pyansys.com/version/0.68/mapdl_commands/prep7/_autosummary/ansys.mapdl.core.Mapdl.cp.html)

 

In general I would select all these set of nodes (e.g., nsel or cmsel commands), and then just use cp,next,uy,all, so:

 

mapdl.cp(“NEXT”,”UY”,”ALL”)

print(mapdl.cplist(“ALL”))

 

All the best
