How does hyper mesh define it's node ids? also, is there a way to define the nodes by coordinates?

 

I need to reference the node # in the script i'm writing and would like to be able to determine the node ID without having to look it up.

    you can create nodes by coordinate(F8 shortcut key).PFA screenshot for same.Also if you want you can renumber node ids.

    <?xml version="1.0" encoding="UTF-8"?>nodes by coordinate.JPG

    You can get node id by coordinates by:

    set NodeId [hm_getclosestnode $xcoord $ycoord $zcoord]

     

    To determine node id that you've just created:

    set NodeId [hm_latestentityid nodes]

    The reason i'm asking is i'm trying to create a script that automatically applies a load/constraint to a certain node after hypermesh has meshed the model without having to manually click on the node i want to apply the force/SPC to.
