Description

ENEFITS in GeniE 5.3 The main focus of this release has been to ease beam deflection reporting and modelling of complex surfaces. Another important change is the ability to import old frame models and results to do result presentation and code checking in GeniE - a typical example is the import of data from existing SRS (structural reanalysis systems). We have made the code checking more flexible. To better support design requirements, users will now have the possibility of not strictly following over-conservative interpretations as given by various statutory regulations. To save time, property update for the mesh is now possible. The changes in the mesh module have also brought other advantages, such as the ability to retain constant node and element numbers of imported frame models. BENEFITS in DeepC 4.5 A major update of this release is the possibility to use regular waves in addition to irregular waves for fatigue analyses. Compared with irregular wave fatigue used for detailed fatigue analysis, the new regular wave fatigue functionality gives fatigue results much quicker in the initial design process. Other important benefits are the handling of direction dependent scatter diagrams and parallel execution to simultaneously run an arbitrary number of analyses. DeepC also supports cross-section drawings, cross-section analysis (capacity curves) and fatigue analysis of helix elements in umbilicals and flexible risers. DeepC has thus become a complete solution for all slender structures such as risers, mooring lines and umbilicals. BENEFITS in HydroD 4.5 Hydrodynamic results such as RAO’s can be calculated based on user defined reference points in addition to the still water line. When sub-modelling techniques are used the sub-model is now independent of the compartment – this means that it is possible to retrieve loads from the compartments even though only parts of the compartment are part of a sub-model. Flexibility in user specification of simulating pressure loading in a zone around the mean free surface has also been introduced. For hydrodynamic analysis of multi-bodies it is now possible to define an additional coupled damping matrix for the bodies. Finally, much larger time domain analysis can be carried out, since the computational engine supports 64bit application technology. Continuing 40 years of success While Sesam has evolved as a market-driven modular system enabling users to invest in a package of selected modules, integrated packages have also been developed to cover specific needs. GeniE is an example of a software package using software modules such as Sestra and Xtract as vital services. Another example is HydroD using Wadam and Wasim and DeepC using Simo and Riflex. There is a continuation in maintaining the software modules. For some of them significant development has lead to new functionality for the benefit of all Sesam users. An example is the ability to run very large beam models – the limit has been lifted from 20,000 to 60,000 beams - with many time-steps in a wave load analysis, for the purpose of performing a fatigue analysis based on the principles of the so-called “Rainflow Fatigue Counting” in the time domain. The new limit represents an impressive increase of a factor of 32 for time steps in the wave load analysis (from 8,192 to 262,144 time steps). Another example is the update of Installjac, making it independent of finite element numbers and automatically re-using the flexible length of each member as defined in GeniE. This means that the buoyancy and mass can be automatically computed based on an imported model. A third example is the new feature in Xtract where users can visualise that the deformations from a sub-model analysis are the same as the global analysis model. Seen from a quality assurance point of view it is a key to document that the basis for the sub-model (prescribed displacements) is the same as for the reference model. Windows XP, Vista and Windows 7 are supported by all software. Market driven improvements Based on feedback from our customers during Sesam development, we are confident that the new possibilities will help engineers be more productive within the design and operation of fixed and floating structures. At the same time new functionality in Sesam allows engineers to do riser design (traditional or based on coupled analysis results) as well as umbilical drafting and design (capacity curves and fatigue). Some of the new improvements are already part of our user courses – see our training schedule on DNV.com/software for more details. Many of our users are already using the scripting functionality in GeniE to make parametric models, customized reporting or other user operations. To make these possibilities more known among all users, we have made a GeniE SnackPack with many examples to learn from. You can find it on our download services at DNV.com/software.
