RIFLEX Task

A RIFLEX analysis.

RIFLEX was developed as a tool for analysis of flexible marine riser systems, but is also suited for any type of slender structure, such as mooring lines, umbilicals, steel pipelines and conventional risers.

1. Work Array Memory Settings

The memory allocation for RIFLEX modules can be controlled using environment variables. The variables specify the size in million bytes (= 4 × million integer words). Allowed range: 4-1600.

Module Variable Default values unit

Number of words

A word refers to a unit of computer memory — specifically a 32-bit (4-byte) integer word. So 9,000,000 words = ~36 MB of RAM allocated to the VIVANA analysis

2. Skip Riflex Dynmod Transformation

Skip transformation, default ☑

  • The times series may need to be transformed for fatigue analysis (OUTMOD ifnfyn-format).

3. Remove intermediate files after run

Remove intermediate files after run, default ☑

4. Export mass units

Options Mg or kg. Default Mg
