GHS Beta-Version Update History since Version 15.50
GHS Beta-Version Update History since Version 16.00
WAIT BReak was added to break out of macros and run files for keyboard command
entry, resuming control when the Esc key is pressed. This is similar to WAIT
without BREAK, except commands can be entered while waiting and names of active
macros and non-persistent templates are displayed to help debug complicated run
GROUND /FLOOR now supports floor files with as few as four points surrounding
GROUND /FLOOR was trapping an error for single-point stations and locking the
floor file after "Invalid floor data" errors.
SEAkeeping was not correctly calculating the pitch hydrostatic stiffness
coefficient when the vessel's longitudinal center is not near zero.
FSMMT MAX [:Keep] subparameter was added to keep the present load instead of
changing it to the load having maximum free surface moment.
DISPLAY STATUS was incorrectly treating WAVE (SPECTRA) as a TROCHOID
wave instead of as OFF (requires updated CG.EXE).
SEAkeeping /SUMmary:[Position] [Velocity] [Acceleration] parameter was added
to conclude the seakeeping report with the specified extreme response amplitude
summary tables (or all summaries if just /SUMMARY is present).
SEAkeeping /CONFidence:percent,hours parameter was added to allow computation
of extreme response amplitudes in irregular waves by specifying a confidence
percentage and time interval in hours. The extreme amplitudes are computed
for all modes and added to the Response Statistics and any Summary tables.
SEAkeeping /GUnit parameter was added to allow accelerations to be returned
in "g" gravitational units instead of current length units.
SEAkeeping /DATA: REsponse subparameter was added to output a Comma-Separated
Values (CSV) data file RESPONSE.DAT recording RAOs, response amplitudes, and
phase angles for vessel CG and all critical points.
SEAkeeping Response Statistics tables now include average response periods
between zero-up-crossings and response peak values.
SEAkeeping updated the formatting of its Response Statistics tables to reflect
the addition of response periods and additional extreme response amplitudes.
SEAkeeping was not correctly computing derived critical point surge and sway
response position amplitudes when the VCG was significantly above or below
VIEW was sometimes omitting the first page header line after a plot and
hanging on lines longer than 4000 characters (requires updated GHSVIEW.EXE).
ENTER PM fitting of a centerline SHAPE into a non-centerline component
was sometimes doubling stations until the geometry is written and re-read
(requires updated PM.EXE).
PTYPE system variable was added to return the type of the current part in the
format shown by the bare TYPE command (empty if multiple parts are selected).
GROUND /FLOOR now traps an error when origin depth is undefined, just like
for non-seafloor ground points.
RA /LIM was sometimes failing with undefined percentage of Deck Immersion
limit angle for asymmetric vessels having greater freeboard at 15 degrees heel
than when upright.
ENTER PM command SURFACE improved rendering visualization in many cases
(requires updated PM.EXE and SE.EXE).
