Appendix A. OC4 Jacket Input File

SubDyn’s primary input file (OC4 Jacket SubDyn's Input File):

This file includes information on the integration method (e.g., Adams-Bashforth 4 th} order), numerical-solution parameters (e.g., integration time interval, static solver flag, numer of modes to retain within the Craig-Bampton reduction), finite element analysis information (beam element model, number of elements per member), and the geometric definition of the beam members via joints, member connectivity, and member cross-sectional properties. This file also specifies any SSI input files (soil/pile stiffness and mass matrices).
