[GiDlist] boundary faces

Dear All,
Say, I have a volume defined by several surfaces. How can I get a list
of the element faces located on some of the bounding surfaces. I was
trying to get it by assigning a temperature load to the surface but it
did not work. I am using gid9.0.2-dyn-64 on Fedora 12.
Thank you in advance. Zdzislaw

Your problemtype must define a condition declared as
CONDITION: your_condition
CONDTYPE: over surfaces
CONDMESHTYPE: over face elements

Then when generating the mesh it will be applied to the faces of the elements (probably your temperature load was applied to nodes)
