To update the hydrostatic sections to the latest Maxsurf Design File, select “Recalculate Hull sections” in the analysis menu after reloading the Maxsurf Design File.

This function can also be used to include/exclude surface thickness or change the number of sections and to change use/not use trimmed surfaces without reloading the Maxsurf Design File.

The “Recalculate Hull Sections” command recalculates Hull surfaces as well as Tank Boundary surfaces (Internal Structure surfaces in Maxsurf). Any tanks and loadcases will also be updated with this command.

Note:

Changes to the Maxsurf design are only recalculated after the new Maxsurf design has been re-loaded into Hydromax. This means that if the model is simultaneously being edited in Maxsurf and Hydromax, it is necessary to:
1) save and close the model in Hydromax
2) save in Maxsurf
3) open in Hydromax, using “Read existing data and sections” to make sure the loadcase, compartment definition etc remain part of the Hydromax design file.
4) use the “Recalculate Hull Sections” from the analysis menu.
