outflow bc
 

greetings
please tell me how to apply 'outflow' bc as available in FLUENT
thanks

Thank you for your question.
Without knowing the details of FLUENT's boundary conditions I can't guarantee identical behavior, however you might be looking for either MARKER_OUTLET or MARKER_FAR, both of which are set in the config file, and examples can be found in the configuration files used in the tutorials:
