Angle for a node

Angle for a node

Angle for a node

(OP)
Hi,

Not sure if this is the right forum but Ill give it a try. I have my pipeline configuration and all the nodes are given in global coordinates. I want to know the angle between my global X axis and the specific node. See my link for explanation. The red dot is the searched node angle. Do you know how I can do?

Thanks!

RE: Angle for a node

I assume from your previous posts that you are using Ansys. You can enter the following at the command line in Classic, or a command snippet in WB to get the angle to node 2631:

csys,1 ! set csys to global cylindircal
angle=ny(2631)

The ny(nodenum) is a "Get Function." These are documented in Appendix B of the ANSYS Parametric Design Language Manual.

Thanks but im not using ansys, im using Simla (FE program for subsea pipelines) :)

I have coordinates for all the nodes (Estern, Northing) but I want to know the angle of a specific node in relation to the global coordinate system.

Thanks

RE: Angle for a node

The node itself wouldn't have an angle. Instead, find the angles of the two elements adjacent to it and average them.

If the elements are linear then just do some trigonometry (atan2, not atan) on the coordinates of their end nodes to get the angles.
