DesignCalcs now supports lifting lugs on heads for the following head types: hemispherical, torispherical, ASME F&D and ellipsoidal. DC-7788
The following enhancements enhancement 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.

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
