Hello all,

Really struggling here. Posted a discussion earlier but no luck. I have come up with an idea, may be that will work.

Is it possible to get node's x,y,z coordinates using APDL?

If I have, for example, 10 nodes where I would apply 10 different forces simultaneously (function of x,y,z), is it possible to do that using APDL?

Any advice/suggestion would be of great help. TIA.☹️

Hi @ruzfactor yes, the *GET command can be used to get a nodes x/y/z position. Please see the MAPDL Help -> Command Guide entry on *GET. There is also a 'short cut' version; NX(n) returns the X location of node n in the current coordinate system. Returning to a parameter value i.e. we can use: n_1=nx(1) that would assign the x coordinate value of node number 1 to n_1. You can use a naming convention that makes sense for you...maybe instead use nx_1=nx(1) or node_position_x_1=nx(1) etc. Anyway gather the y and z position similarly and then run the values through the function etc.
