Hi,

When i am doing a WRC evaluation using CAESAR, I am being asked to input direction cosines for nozzle and vessel. My vessel is a vertical vessel and hence cosine in Y is 1. My nozzle is on top of dished which is also in vertical direction. Hence I am making my nozzle cosine also 1. But I get an error "Directional Cosine of the Vessel and Nozzle Should Be Orthogonal". What should I do? my nozzle is not orthogonal to vessel.
