The program RISER3 is one of the programs available in the section Offshore Engineering.

RISER and RISER2 solve the riser displacement and stress problem in the frequency domain. This implies a linearized calculation model, RISER uses a continuous integration of an assumed harmonic solution. The boundary conditions are satisfied by shooting. RISER2 uses a FE solution for an assumed harmonic solution. Both programs work with complex quantities.

RISER3 solves the riser displacement and stress problem in the time domain for non-linear conditions, using a FE solution. The Newmark-beta=l/4 method is used for integration.

The program RISER3 is public domain. It may be used, copied and changed by anyone. Any responsibility is excluded.
