XY plotting pressure coefficient on the wall
 

Dear Fluent Users,

I solved the flow around the 2D obstance in Fluent. I used XY plot, Pressure, Pressure Coefficient to obtain distribution of pressure coefficient on the obstacle wall. But the values are overpredicted.I obtained -200 as pressure coefficient. it is not logical. What must I do to obtain logical pressure coef. (between -1<Cp<-2 ) Thanks

Use proper reference values od area, velocity, etc in the reference values panel.
