As directed by you, I tried the export mesh feature in netgen, although .tet format is not working. Also, the major problem arises when i want to import mesh from different mesh generators as we use netgen for generation of our basis functions on imported mesh. Although, I tried the import mesh option which can take in (A) neutral format (b) surface mesh (c) universal format and few more, I encountered the following problem: Even when I am exporting a .vol file in neutral format and then trying to import this mesh into netgen, The mesh is missing a surface. I don't know whether its a glitch in graphics or not.
Also can you please explain me the meaning of few notations in .vol mesh which are as follows:
# surfid 0 p1 p2 trignum1 trignum2 domin/surfnr1 domout/surfnr2 ednr1 dist1 ednr2 dist2

I would be very obliged if you explain what these notations means in .vol file
