I'm doing my final year project on Natural Convection in fin array.. I investigate the Natural Convection of the air domain. I created 3D volume of air which partial of the face of that air volume is fin wall and base which temp constant, i set th BC as below:

Fin wall -Wall (constant temp 400K)
Fin base -Wall (constant temp 400K)
Other surface = Pressure inlet and outlet randomly (both oso "0" presure)

And

Operation Condition = 101325 pascal, 300K temp and tick gravity
Material = air with density 1 under boussinesq
Solution Initialization = all zero value

But i got error ms as:
----------------------------------------------------------------------
No error handler available

Error: FLUENT received a fatal signal (SEGMENTATION VIOLATION).
Error Object: ()

Error message from graphics function Close_Segment:
Nothing open - can't Close a 'segment'
