I'm having some difficulties to run wrc 107 program in coadecalc when entering the loads from Caesar II global coordinates, so I hope somebody could give me some tips.
The problem is the following:
When I enter the loads in the wrc 107 convention I don't get the stress summations, so I'm entering the loads in global coordinates. But the problem is that I'm not felling confident of entering the direction cosines rigthly since I didn't understand the convention described in the user's guide.
I just know that the nozzle vector is always defined to point to the centerline of the vessel. But what is the convention I have to use, for instance, when analying a horizontal vessel with a nozzle on the shell?
And another situation is when I have a nozzle on the head. What is the vessel direction cosines?(I know that it can't be colinear with the nozzle centerline.)

Regards,
