• A table of used materials is now available, etc.

START version 4.81 release. This version has many new features including:

• Added new code ASME B31.1-2016 Power Piping (United states)
• Added new code DL/T 5366-2014 Power Piping (China)
• New materials are added into START material database according to ASME B31.1-2016 and DL/T 5366-2014 codes
• Added China General Expansion Joint () into Expansion Joint database
• Fixed some minor bugs

A new version Nozzle-FEM 2.13 is now available, which has a number of additional options, including strength calculation at low-cycle loads as per i.7 GOST R 52857.6-2007 (refined low-cycle strength calculation).

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.
