pressure coefficient

      In fluent,What is the definition of pressure coefficient by fluent,Is the difference between the local static pressure and the far-field static pressure divided by the far-field dynamic pressure?By definition. Its value cannot be greater than 1,In my case, this value is greater than 1,I calculate the far-field velocity of multiple different points with pressure coefficient greater than 1 in the flow field,It is found that they seem to have the same far-field velocity,but not the speed I set for the Velocity inlet,I'm sure my reference values are correct. So, what is the definition of pressure coefficient by fluent, In particular, what is fluent's definition of far field velocity. Sorry, I didn't find the relevant instructions in the help guide.
