1. Riser type specification 1.1. Data group identifier, one input line NEW SINGle RISEr 1.2. Selection of riser type and identifier ATYPS IDRIS IDCON ATYPS: character(6): Riser code type for single riser. Allowable codes are listed below: SA: Next data in Standard system SA SB: Next data in Standard system SB SC: Next data in Standard system SC SD: Next data in Standard system SD AR: Next data in Standard system AR IDRIS: character(6): Riser identifier IDCON: character(6), deault: NONE: Normally not used! =LAYFLX Roller contact forces are dumped on data files for LAYFLEX post-processing. Static roller contact forces will be output to the file prefix_consta.asc. For nonlinear dynamic analysis, time series of roller contact results will be stored on the file prefix_contts.asc and key results will be stored on the file prefix_condyn.asc. Storage of data to prefix_consta.asc, requires that IPRFEM=-1 in Options and print switches in STAMOD. One or several riser specifications may be created and stored by one run of INPMOD. The identifier IDRIS is used by STAMOD to select one particular riser for analysis. Slender system Standard system SA
