pressure coefficient
 

Dear,

i have a queation regarding cp?
in order to plot pressure coefficient along the circumfernce of cylinder, firstly i create a ployline by using boundary intersection method in which i select cyl_1
for boundary list & symmetry1 for intersection.
because i have 2D problem

then i plot a graph between Cp Vs chart count ,actually i am unaware about this terminology "chart count" & i want a plot between Cp Vs theta
similar approach for Cyl_2

how i convert this X axis variable" chart count" into "theta" variable.....

Create variable theta = atan2(x,y)?
