    27. Nozzles. The effective thickness of the nozzle in the analysis of compensation for the codes VSR and EN 13445 has been updated. When the thickness of the nozzle is in excess of the one read from VSR Fig.1.K.2.1 or from EN 13445 Fig. 9.4-14 then the analysis is performed at the maximum allowed thickness and a warning message is sent to the user. (3.1.3)

    36. Skirts. The calculation of the base skirt diameter has been fixed. The external diameter at the base of the skirt was not in agreement with the diameter specified in input. (3.1.4)
    37. Materials The values of the Young module of the material SA 516 Gr.70 have been changed with the values related to "Carbon <= 30%"(3.1.4)
    38. Messages The warning message U0102 has been fixed. The temperatures referred in the message are in °C and not in °F..(3.1.4)
    39. General Notes The management of the General Notes on the drawing has been fixed. When the note descriptions overcame the number of placeholder \$ the drawing generation went in error.(3.1.4)
    40. Bill of Material The Bill of Material has been fixed. The weight of conical sections (both Net and Gross) was multiplied 2 times by the number of sheets required to form the cone.(3.1.4)
    41. Drawings The vessel drawing has been fixed. For adiacent conical sections the cones were drawed with knuckles even for cones without knuckles.(3.1.4)
    42. Cones The calculation of the cones to external pressure according to ISPESL-VSR has been revised. In check calculation the values of the stiffening rings specified in input were not taken into consideration for the check of the stiffening rings and for the check of the junction cone-cylinder.(3.1.4)
    43. ASCII Report The printout of the warning messages on the tabular report has been extended over 20 message.(3.1.4)
    44. Saddles The value of the saddle width (b on the sketch) passed from the standard to the calculation module has been fixed. The previous value was referred to the width of the transition plate.(3.1.4)
    45. Saddles The value of SI (saddle bearing angle) shown on the schema of saddles "user standard" has been modified to point to the saddle edges. In the previous schema SI was referred to the transition plate edges.(3.1.4)
    46 Codes. The ASME VIII Div.1 code has been updated to the Edition 2007. (3.2.0)
    47 Codes. The ASME II – Part D (materials) has been revised to the Edition 2007. (3.2.0)
    The following ASME charts for vacuum have been revised or added:
    • NFT-3
    • NFT-4
    • NFT-5
    48 Nozzles. The rings for opening compensation has been added to the nozzle module. (3.2.0)
    49 Nozzles. The option Large Opening ASME per App.1-10 has been added to the program. (3.2.0)
    50 Miscellanea. A new code to memorize the last units system has been added to the program. The new calculation now starts with the last used units system. (3.2.0)
    51 Miscellanea. The possibility to review the results of previous calculations without the need to rerun the calculation has been added to the program. (3.2.0)
    52 Report Book. The hydraulic test pressure module has been added to the Audit Report Book. (3.2.0)
    53 Report Book. The "adjacent nozzles summary" has been added to the Audit Report Book. (3.2.0)
    54 Flanged flat heads. The calculation datasheet related to flanged flat heads per EN 13445 has been fixed. In check, the number of bolts was not printed. (3.2.0)
    55 Messages. To make easier the understanding of the diagnostic messages, the sequence number of the nozzle has been replaced with the nozzle item in all the diagnostic messages. (3.2.0)
    56 Cones. The stiffening rings distance for cones to external pressure has been added to the program.
    57 Support legs. The tubular legs have been added to the legs module. (3.2.0)
    58 Support legs. The option to verify the loads generated by the legs over the shell by WRC 107 has been added to the legs module. (3.2.0)
