Nice tip Richard for setting 0.001 for those values that I want to zero out such as Cl=0.001 and Ca=0.001. It works now, the output is now Fx and Mz only with all other components almost zero. Now I understand how Caesar II works regarding setting these coefficients. This means Caesar can automatically calculate these coefficients based on the given data.

Theoretically speaking, is it correct to say that for a vertical pipe there is no lift (Cl=0.001) and only buoyant force in the vertical direction going up? Or there is a lift with the area being the diameter of pipe (Pi*D^2/4)? Can this be captured in the software?

Any other opinion is greatly appreciated.

Please correct me if I have a wrong interpretation in my statement.

Cheers!!
