Inlet properties don't work

I have created an inlet but cannot change the properties even when select it and go into the menu, properties, Physics and it just says inlet with nothing below it

Please help

Requires Substance

Did you add a Substance to your volume first?



More details please

What are you trying to simulate?

Assuming you are simulating a CO2 dragster, have you successfully completed the tutorial "Flow Over a CO2 Dragster"?

Do you have a single water tight volume of the air around your car as in the tutorial? I would guess this is likely your problem. For more details see "CFD Flow Volumes and Solid Models".
