Hi,
I am doing nonlinear static with NX Nastran to determine the shape of a overhead substation conductor. Based on different litterature on the subject i model my conductor as a beam element. i Run different case to reach my final shape. First, i apply the weight as a load, second i apply node displacement and rotation to my constrained node. So far everything works well. i have only worked on the x and y plane. The problem is when i try to apply a wind force on the z plane i am not able to make it converge. It crash after the first iteration of that case. I have realized that i am not even able to make a displacement of a node in the z axis. i am using newton raphson solver.
Can anyone help me determine why i cannot apply force or displacement in the z axis?
Thanks for your help
