[Gmsh] How to select Pre/Post processing entity by location?

[Shamsul Arefin]

Is there no other selection by location option? Say I want to select the areas at 'z=0', or volumes between -10<x<+10 and -10<y<+10.

The purpose is to select nodes from a particular geometric entity and define name for those nodes i.e. a nodal set. 

Usually when I know the ID of a surface (for example), i can define a "physical surface" and get the nodes and elements in the output-file grouped together. Problem is, I would not know surface ID's while working in the batch. 


Or anyone has a better idea for doing this with gmsh?
