Sectional force coefficients
Greetings to all,
For Bluff Structures, OF has the excellent forceCoeffs utilities to calculate force coefficients, which are defined as drag coefficient Cd = Fx/(rho*U^2*D*H/2) and lift coefficient Cl = Fy/(rho*U^2*D*H/2). These are actually the averaged force cofficients along the bluff body. Sometimes, we need to know the sectional force coefficients at a certain crosssection along zdirection, which can be formulated as Cd(z) = Fd(z)/(rho*U^2*D/2) and Cl(z) = Fl(z)/(rho*U^2*D/2). They are obtained by integrating the pressure and shear stress over the circumference of a cross section. Are these calculations for sectional force coefficients available in OF? The answer is probably no. Then, can anybody please suggest a way on programming to realize this utility? (I am not familiar with C++, :o, so please give a little bit more information.) Cheers, Albert 
hi albert, I'm facing the same problem, have you found the solution to this question?
