GeniE v6.0 – BenefitsFull support of 64 bit technology will give our users access to “unlimited amount” of memory. This will in particular help out when modelling very large models, but also during code checking of models with a significant high number of load cases.

Furthermore, it can import additional Sacs data and the code checking has been made even more flexible for the ISO standard.

Released December 2011


SesamTM

3 December 2012

6

Sesam GeniE – now a 64 bit application

� 32 and 64 bit applications – “unlimited access to data memory”- Much easier to model and analyse large models with 64bit

- The model below was successfully made in 32bit – easier now- 165.000 beams, 200.000 shells, 1.000.000 dof, 41 LC

A typical Sevan FPSO


SesamTM

Much more complete import of Sacs data

� Load combinations

� Handling line loads on segmented members with more than 3 segments

� Better warnings during import of Sacs data

1000+ load combinations

plates


SesamTM

3 December 2012

9

GeniE v6.1 – Main benefitsOur users can now maintain and control the finite element numbering of beam models. This also applies to imported models from FEM or Sacs format.

The manual labour to redefine wave load data for imported models is no longer needed as GeniE can import wave load date from older Sesam format and Sacs.

GeniE can now include tension or compression elements in linear analysis to the benefit of e.g. lifting or jack-up analysis. Ask us for a utility tool to run Sestra tension/compression analysis.

Beams in X-joints can be fully disconnected. This leads to a sound non-linear analysis model as well as improved tension/compression analysis.

Released March 2012


SesamTM

3 December 2012

Import wave load data

� Importing all hydrodynamic properties and wave load data from Wajac or by Sacs

10


SesamTM

3 December 2012

Tension/Compression (T/C) analysis

� Example uniform upwards load- You need a utility tool from us to run T/C analysis- Sestra v8.5 or later needed

12

Tension elements contributing to stiffness

Positive SIGXX

Compression elements not contributing to stiffness

No axial stress

Compression/tension (truss) elements contributing to

stiffness


SesamTM

3 December 2012

Tension/Compression (T/C) analysis

� Verified against Abaqus, Usfos and theoretical calculations

� Iterative process using Sestra for each step- convergence quickly achieved

15

GeniE v6.2 – Main benefitsA major upgrade of all beam code check standards reflecting the latest code check revisions as well as providing more user control in the use of code check formulas

A more robust data import from Sacs with respect to point and line loads on members with very large eccentricities

Released April 2012


SesamTM

3 December 2012

Supported code check standards

� Eurocode 1993-1-1 includes corrigenda - NS-EN 1993-1-1:2005/AC:2009- NS-EN 1993-1-:2005/NA:2008/AC:2010

January 2007 (joint capacity check)

16


SesamTM

3 December 2012

Joint checks updates (all codes)

� Azimuthal angle tolerance- The user can now define azimuthal tolerance angle for joint

design. This provides the possibility to define different sets of braces to be used on Joint Punch Check Analysis

- Previous GeniE versions used 5 degrees as default value

� Define Brace - Can End distance- Define Brace - Can End distance in opposition to the only

method used before (min distance). - This option gives the individual brace - can end distance for

the joint punch analysis.

19


SesamTM

3 December 2012

Cone checks updates (all codes)

� GeniE allows users to choose between internal forces on cone structures or adjacent forces on tubularsclose to transitions points for Cone Code Check Analysis

� GeniE has two ways of retrieve axial forces for cone code checks. - Default behaviour: Conical internal forces - the internal

axial forces are retrieved- User option: External forces - in this case the forces at the

transitions are retrieved

Usfos v8.6 – Main benefitsMore strict checking of the finite element model to ensure that the model is fit for use in non-linear analysis.

There are new program defaults and accuracy parameters that will help the user during analysis and joint capacity checking

In addition several enhancements in the user interface for graphical verification of the model as well as easier hydrodynamic.

ReleasedJune 2012


SesamTM

3 December 2012

34

Stricter data check of the imported model

� Element length vs. diameter- Very short elements could cause unnecessary numerical

problems- If L/D < 0.5 Usfos will stop and report this as an illegal short

element

� Eccentricity vs. element length- Source for numerical inaccuracies when extreme eccentricities- If (e1+e2)/L < 0.5 Usfos will stop and report this as an illegal big

eccentricity

� Soil thickness vs. pile diameter- In a normal pile-soil model, the soil thickness is typically 3-10

times the pile diameter- If Thick/D <1.0 Usfos will report this as an illegal thin soil layer

� You may over-rule these data checks- In most cases not recommended


SesamTM

3 December 2012

Examples on better graphic verification

� External pressure (now automatically computed)

� Pile/soil – in this case viewing the T_Z curve
