  • DesignCalcs now exports to AutoCad Autodesk Inventor. DC-8828, DC-9118

Notetip

Note:
Additional features relating to the AutoCad Autodesk Inventor export will be expanded over the next several releases. This initial release exports cylindrical shells, hemi heads, torishperical heads, conical heads and conical reducers. For more information, see the AutoCad Autodesk Inventor Integration page.

  • DesignCalcs now supports lifting lugs on heads for the following head types: hemispherical, torispherical, ASME F&D and ellipsoidal. DC-7788The following enhancements have been applied to the wind and seismic calculations:

  • The seismic inputs for Fa and Fv now determine seismic loads based on the user input or the greater of the values from the Seismic tables. Previously, these inputs were only used to fill in gaps in the building codes for the more severe site classes E and F where the values were not provided. Therefore, the Fa and Fv values for vessels patched with older versions of DesignCalcs are now set to zero for site classes A, B, C and D as well as new vessels; values from older versions are set for site classes E and F. DC-8966

Notetip

Note:

DesignCalcs uses the greater of the input or values determined by the tables in the building codes. This update affects building codes for 1998 and later.

  • DesignCalcs now includes ASME B16.11 2021 code changes. DC-9041

Notetip

Note:

The latest code changes specifically affect 9000# socket weld coupling thickness in millimeters and how the software handles these values. For more information, see the Pipe Fittings and Long Weld Necks Dimensional Data page.

When running a Zick Analysis, if more than one liquid row is input, the software recognizes the inputs as though only one row exists, and calculate calculates based on the max depth and max liquid density of all rows. If multiple entries exist, an increase in the vessel weight for the operating condition calculations can occur. Previously, multiple liquid inputs for horizontal inputs were resulting in a low liquid weight, which made results unconservative. DC-8871
