There should be option to un-check B31J even if we use Ed.2020.
This will help during anlaysis which comprises of both ASME Sec-1 & B31.1 pipes. Hence there should be an option to uncheck if not required.
By default it should be “ticked” but if user want to uncheck then this should be available.
Since the latest ASME codes mandate the use of B31J, there is no way to calculate flexibility or SIF's without it. So we cannot turn it off. We also cannot analyse multiple codes in one analysis as yet, this is something we are looking at doing and at that time the inclusion of B31J might be at the node level.
