Non-Reflecting Boundary Conditions
 

Hello there,

I have a problem with an error message as below:

Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: ()

This is displayed when I have already solved the simulation using the coupled implicit solver. And then I activate the non-reflecting boundary conditions ,and when I start to iterate, the above message is displayed immediately.

When I print the status of the non-reflecting boundary conditions, this is displayed:

/define/boundary-conditions/non-reflecting> show-status non-reflecting b.c.'s are active under-relaxation factor: 0.75 use reconstruction? : #t verbosity level : 1

I have already changed the inlet boundary condition as pressure inlet and that for the outlet boundary condition as the pressure outlet with the direction specification method as direction vector.

Please let me know what seems to be the problem. Thanks in advance,

Regards,

Shadab.
