fatal error

[LoSte]

ciao a tutti ho un problema con fluent e spero che possiate aiutarmi
dopo aver importato la mesh, scalato il modello impostate le condizioni al contorno e il tipo di risoluzione avvio l'iterazione.
e fin qui tutto ok
in un secondo meomento qnd gli chiedo di plottarmi le pathlines per verificare come varia la pressione o la turbolenza all'interno del sistema mi da qst errore:


error message from graphics function kopen_segment:
syntax error during expansion of 'path-1-turb-kinetic-energy' -
specification did not start with root ('/'), and no segment is open


no error handler available

error: fluent received a fatal signal (segmentation violation).
error object: ()

error: cx-display-bnd-frame: no active window.
error object: #f

preceduto da un interminabile lista di messaggi del genere:

qualcuno saprebbe darmi una mano per identificare l'errore?
è un problema di simulazione?
di mesh importata con gambit?
