GeniE
The new features in GeniE v5.1-11 are particularly related to code checking of plates (DNV RP C201.2 or PULS), re-use of data as defined in DNV rule check of tankers to create a three cargo hold model, improved finite element meshing capabilities, and better support for modelling of very large models using 64bit technology.
FPSO modelling and PULS code check
To support strength assessment of three cargo hold models according to the CSR Tank rules, the following have been implemented:
- Rule load xML exchange with Nauticus Hull
- Co-centric stiffeners, i.e. idealised, noneccentric stiffeners based on a given eccentric flange
- PULS (DNV RP-C201.2) linear nonlinear buckling check for stiffened and un-stiffened panels
The implementation is generic and can be used for plate code checking of e.g. offshore structures.
Support for parallel installations
GeniE will no longer be installed to a default location, but to a program version dependent number. You can thus continue to access your old projects using the previous version of GeniE.
General improvements
- Creation of mesh quality, especially related to models with cut-outs
- GeniE will run a data check on the mesh quality and list which elements (and their belonging to a plate) will fail in a Sestra analysis.
When executing GeniE on a 64bit system, the available virtual memory has been extended from 2GB to 4GB allowing for larger models.
Installjac
Version 8.0-03
- Implementation of eccentricities replacing use of end-cuts. You can choose to use the eccentricities as calculated by GeniE when creating tubular joints with gaps and/or flushing instead of defining end-cut data
- Improved print-out of element end forces and moments at the ends of the flexible parts in addition to the joint ends.
HydroD
Version 4.3-04 incl. Wasim 4.3-04 and Wadam 8.1-09
Morison model in Wasim The full expression of time domain Morison formula is taken into consideration on the 2D Morison beam elements defined within the Morison model. Pressure area elements are also considered to calculate the Froude-Krylov force and hydrostatic & buoyancy force acting on the Morison model. This feature is only relevant to non-linear analysis, since the nonlinear drag term of the Morison formula is involved.
5th order Stokes wave model on finite depth in Wasim has been implemented with both infinite and finite water depth defined in “location”. This feature is only relevant for non-linear analysis. We recommend that you check the validity of 5th order Stokes wave model for very shallow water.
Wave elevation output for Wasim Wave elevation can now be exported to a file. To activate this function, offbody points with a zero z value should be defined in HydroD. The time history of both incoming and total wave elevation at the specified points will be output into a file (*.wel).
Models in [mm] in Wasim The input models (pln file, structural model, etc.) to Wasim can be in units other than metres. To be able to handle models in millimetres, the length database unit must be set in mm in HydroD when defining a new workspace.
General transformation for Wasim A general coordinate transformation has been introduced in the Wasim mesh activity; damaged cases can now be simulated directly without a transformation preprocessing step.
HydroD Mesh user interface Users have more flexibilities and possibilities to refine and tune the mesh on free surface.
Composite model A single superelement composite model has been implemented for Wadam; you no longer need to have the panel and Morison model as separate superelements.
Multibody analysis in Wadam can now run up to 15 bodies.
Support for parallel installations
HydroD will no longer be installed to a default location, but to a program version dependent number. If you choose to use parallel installations, you need not uninstall the previous version. You can access your old projects using the previous version of HydroD.
Please be aware that the HydroD installations will use the same Wadam and Wasim versions.
DeepC
Version 4.4-03 opens up for a wider usage of DeepC as it is now fully capable to perform riser design. The new version has features that are particularly important for risers; for example, functionality for pipe in pipe contact forces and flex joints.
For traditional coupled analysis, it is now possible to perform decomposition of result forces and moments and use initially stressed segments.
There are also new features to attach supports or fairleads to lines, and it is possible to have overlapping lines.
