Hi everyone,
I am working with wing in wavy effect (like this https://www.researchgate.net/publica...d-Effect_Craft)

when i set inlet and outlet of the wavy ground domain as pressure far field, only 1 have match Mach number with boundary condition and other down to 0,5 time.
I trying to set inlet and outlet as periodic repeat but the solution value between 2 interface not matching with other

I dont know how fluent apply boundary condition and why solution value not matching with set value. Can anyone help me to explain it?

make domain bigger, use pressure far field as boundary condition
