Thanks for your reply Jason.
You made me question myself but I downloaded a new copy of the DC version from the website wind.nrel.gov/designcodes/preprocessors/bmodes/ to be sure. The additional supports section including draft etc. is included in the design codes website version. Line 590 onwards in bmodes.f90 are:
[code] if ( tow_support == 2 ) then
! platform data
CALL ReadVar ( UnIn, InFile, draft, 'draft', 'depth of tower base from the MSL (mean sea level) (m)' )
CALL ReadVar ( UnIn, InFile, cm_pform, 'cm_pform', 'distance of platform c.m. below the MSL (m)' )
CALL ReadVar ( UnIn, InFile, mass_pform, 'mass_pform', 'platform mass (kg)' )[/code]
Here is the header from the .out file for CS_monopile.bmi:
Results generated by BModes (v3.00.00, 20-Mar-2008, compiled using double precision) on 22-Jan-2013 at 16:17:20.
