Hello,

Please let me know what direction cosines should be selcted for WRC analysis of nozzle on Head using CEASER analysis file. Selecting 1 for both nozzle & Vessel Y co-ordinate gives geometric error.

Please revert.

Regards,
Bipin

For nozzle on head select X-axis for the vessel and for the nozzle select Y-axis.

For vessel (shell or head) the direction is from point B -> A (as per WRC 107 convention). See the attached illustration.

For WRC 107 the vessel-nozzle should be perpendicular.

If you are still confused, if you write to me, I shall explain them to you. Write to me at techsupport@coade.com.
