velocity boundaryField
 

hi
i have a simple question which i hav'nt been able to find answer.
my inlet for a curved pipe is not parallel to any of the global axis, so how do i set the inlet velocity normal to the inlet face?
my inlet face is about 30deg to the xy plane...do i have to set up a local axes system on the inlet face?
please help
thanks

You need surfaceNormalFixedValue
