I think there is a bug in the WRC 107 program that should be fixed.
After I filled all the information to run the WCR107 program to one nozzle condition I added a new item and changed just the loads data.(the nozzle was the same but in a different condition)
When I analyzed the file I found something strange. The S.I allowable stress in the stress summations returned wrong values for the new item. (20000, 30000, 60000 Kg/sqrcm for Pm, Pm+pl, Pm+Pl+Q loads)
After I checked all the information I'd inputed I realized that the material for nozzled/vessel was changed to the default one. (SA-516-70)
Then when I changed the material to the correct one, in my case (SA-106 B), the values of the S.I stress returned right.
I don't know if I did something wrong but If I'm correct maybe this is a bug that could be fixed.

I have encountered this same problem, after adding an item the nozzle material defaults to sa-516-70 for the new item instead of the using the previously selected material.

Thanks for pointing the problem out. This has been fixed in the development version 6.3. This version should be available in December.

Thanks for bringing this to our attention.
