how to segregate nodes in ANSYS?

I have some selected nodes in model, kind of two patches separated at some distance. How to separate these two patches using ANSYS APDL code? The image shows selected nodes and local coordinate system created at location, lets say i want to keep only nodes which are near to local coordinate system and the also the nodal distance varies each and every time.

Solution

  • I think you are looking for reselection frum current set. Assuming your set is selected and the patch sizes in X-direction is xwidth.

    You get the nearest set with:

    nsel,r,loc,X,-xwidth,xwidth
cm,set1,NODE

    Then Reselect all and unselect first set:

    alls
cmsel,u,set
cm,set2,NODE
