I'm using ansys.mapdl.core in addition to using an example from the documentation directly from the official ansys page, but I don't know why I can never go from this part, I already tried to convert it to str as the error says, but still no can.
I used exactly the example from the official website, and everything runs perfect except mapdl.k
Did you assign different id or coordinate to the same keypoint? I think this might be the reason error happen.
