delete an element set from abaqus *inp file

Hi every body,

I need to delete an arbitrary set of elemets in abaqus *.inp file before analysis running.

I tried to remove elements with this command in inp file-> (*Model Change, remove), But it does not work. may be because the model is 3D. (a tube)

Is there any way to delete a set of elemets in inp file? or I should write a python script for that?

I appreciate any hints on this problem of mine.

Thank you in advance.
