[FLASH-USERS] Flow Reversal for Windtunnel with Gravity

[Nitesh Attal]

Hello All,
I intend to perform a Multi-species laminar buoyant Jet simulation.
I began with the turning on Gravity in the Supplied Windtunnel test 
problem.
The Windtunnel test problem when ran with constant Gravity results into 
complete flow reversal (towards xl-boundary). Even when the xl-boundary 
is made outflow flow reversal is observed.
Is this a known issue? Could some one suggest how to overcome this?
Thanks,
Nitesh
