Problem:
What are the geometrical / dimensional limits are checked in WRC calculations?
Solution:
You can see which parameters AutoPIPE Vessel check against the WRC code in the report, refer report snap for your information.
Report shows which parameters are out of scope in red font and gives an error message, so you can change the nozzle details and keep it within the code limit.
The highlighted red ratios are beyond the geometric parameters of vessel that's why the results are extrapolated, and you are getting Error Code 52. For more details on Error Code refer wiki Link here.
"WRC local load analysis method is based off of analytical and experimental data and is only applicable for certain specific range of the ratios of the geometric parameters of the vessel e.g. vessel wall thickness, nozzle thickness, nozzle diameter and vessel diameter. Whenever these ratio ranges are exceeded the WRC method is no longer valid and AutoPIPE Vessel issues an error message (eg. error code 52) and user may select another method of analysis available in AutoPIPE Vessel e.g. PD 5500, EN or GOST. However, similar to WRC, these methods also impose limitations on critical geometrical parameter ratios hence in case where all these local load options are invalid, the user may use other methods e.g. Finite Element Analysis to perform the analysis."
