-To describe the **Velocity** at the inlet, set the option `INC_INLET_TYPE= VELOCITY_INLET`. The format for `MARKER_INLET` then is the marker name, followed by the Temperature (in Kelvin `[K`]), the Velocity magnitude (in meter per second `[m/s]`) and the flow direction unity vector (in meter per second `[m/s]`).
