i used software Gambit tp construct a model of dump bell shape. after saving, i converted it to mesh format and then read it from Fluent 6.

but it shows that there was error. the error was no cells in zone, id = 0, ind1 = 1, indn = 0Reading cellsL failed while reading section 12. clearing partially read grid. it seems to be a critical error. as i already meshed the whole 3-D shape.

so what go wrong and how can i know where is thezone of id = 0 ?

thanks

"after saving, i converted it to mesh format " ,, did you export the mesh to fluent format??? (file->export->fluent)

i convert it to Fluent format
