Thermal stress cycles are not included in PV Elite. For thermal loading, you need to know the temperature difference between two critical points on the vessel, where those points are and the precise temperatures of those points. The temperatures are changing all the time, and mapping the places where those temperatures are at each moment in time is an impossibility, unless you have very specialised software. This is the reason we have not included thermal fatigue in the programme. If we included it, the user would be asked questions he/she could not answer.
