Dear sir

While performing U-Tube sheet calculation for sandwich tube sheet ( Tube sheet gasketed both side shell and channel - Configuration d)

as per code Elastic-plastic calculation can only for Configuration a,b,c,e,f. Not for configuration d.

my query : Why PV Elite perform Elastic -Plastic calculation for configuration d. it seems to be incorrect.

Further, similar error was observed for simply supported calculation(UHX-12.6). However, for simple supported calculation PVElite giving some error in Report.

we expect that whenever confirmation-d : option of simply supported and elastic-plastic should be in-active.

Regards
Vishal
