PASSAT new version 2.11 is now available, that includes a number of additional calculations, corrections and options. Calculations of elements as per ASME VIII div.1 are added (cylindrical shells from impact of external loads; cylindrical shells at locations of saddle supports; cylindrical, U-jackets, spiral and register channels); WRC 537 (instead of WRC 107), as well as calculation of weights and centers of gravity per the elements and for the complete vessel are implemented.
