mesh_renumber

Dear Colleagues,
I read a mesh generated earlier.
I wish to edit it by removing a group of
nodes and bar elements.
However, I want to leave the numbers
of the remaining nodes and elements not changed.
(It is always a comment “mesh renumbered”.
mesh > edit mesh > delete > elements

could you help with it ?
This is gid 9.

regards,

While using the command to delete elements (mesh > edit mesh > delete > elements)
click the right-mouse button and in the contextual menu select the option
NoRenumberEntities
then select the elements to be deleted

and by default isolated nodes will be deleted when deleting elements, you can avoid it with the contextual command
NoLowerEntities
