Hi YJ

That RESP command is an Mechanical APDL command.  It is not a WB Mechanical function/feature.  You can look up that command in the Ansys MAPDL Help - there is an example on using it though it assumes that a time transient analysis has been done and uses the displacement time history of a node as the input.

There is a LF post on using this though it looks like the format got messed up somehow; there are "n" instead of new line character so it's all one big paragraph!  Here is the link to that:
