New Features

Modelling

• Removed warning when user tries to use millimeter as database unit, since "m" always to be used as length unit within ACIS. This makes it possible to use “mm” as database units. (IM3802)
• Added support for dividing a polycurve into two new polycurves with a knuckle point and support for specifying end tangents for a polycurve (IM4696)
• Added GUI application of hydrostatic pressure in the general pressure function dialog, by option to limit the pressure function to positive values. (IM3558)
• Meshing rules - added 2 settings missing from GUI. (IM4824 )

Graphics

• Added isplay of reaction forces – numeric labelling (IM574)
• Changed efault color on Beams and FEM beams elements changed so that they are more easy to see relative to Plates and FEM shell elements (IM4871).
• Preview copy/move is now the default option in graphics settings (IM4865).

Analysis

• Wrong results will no longer be shown when 2 or more analyses. If the analysis has been executed, the results from the active analysis will now be shown when setting it as active. (IM4646)
• Switching Active Analysis to the corresponding Capacity Manager when issuing Set Active, Generate Code check loads and Execute code check from the browser. (IM4876)

Reporting

• Added finite element information to the report (IM4529)
• Added compartment and compartment load information to the report. (IM4618)
• Added mass summary in report. Total mass and COG table added. (IM4796 ).

• Report FEM model : FEM Elements & FEM Nodes report now including concept reference in the first column, to be consistent with "Old Save Report" (IM4529).

Bug Fixes

Modelling / Graphics

• Corrected problem model becomes extremely slow when snap plane is turned on. (IM4681)
• Corrected crash when making a multiple selection, and trying to modify line loads (with beam or line footprints) from the "Properties" dialog (IM4744).
• Fixed several issues with definition of fillet curves (IM4670)
• Fixed display of guide curves. Snap points display was flipped. Some flipped curves were not displayed at all (IM4671).
• Corrected problem that when modelling soil layers, the seabed Z value must be applied first (IM4701).
• Corrected problem that it was not possible to change a wet surface selection to <none>. (IM4813)
• Copy operation of flat plate fails when compartments involved. (IM4802)
• Divide a closed curve does not work. (IM4799)
• Genie crashes when interacting with collapsed guiding geometry (e.g. guide curves with no length). (IM4790)
• Snap points does not match the mouse cursor. Mouse point does not select the closest point on the curve
• GeniE crashes when color-coding the section and double clicking a beam. (IM4758)
• GeniE crashes with Shifting between Beam and Segment selection (IM4763)
• Not possible to define a isotropic shear material from dialog. (IM4820)

• Insert guide line dialog and Insert guide line leads to different number of snap points (IM4833 )
• Display error: pyramid shaped water (IM4834)
• When no growth rate defined for global mesh density, a value is still read from the model and set on the model. Also, there is no test on whether growth rate is less than 1.0 (IM4822).
• Model disappears when zooming if lights are turned off. It turns out that this only happens if attribute locking of the visibility of light is in place. (IM4788).
• Error in summation of presure functions when more that 2 functions superimposed. (IM4825)
• Crash after dividing a beam then selecting another point. Curves not automatically removed from set when deleting curve. (IM4768).

• Joints are at occasions becoming invisible in the graphics (IM4872).
• Section properties change for segments of beam after divide operation (IM4882).
• "Labels -> Load Intensities" not working for point load (IM4881).
• Regression: Closed fillet curve does not work (IM4895).

Meshing / Analysis

• Corrected problem with 'Scaling of Mass' does not work for 'Shear Material' (IM4827)
• Corrected problem where all point loads were not transferred to mesh (Gamesha) when unused nodes were automatically removed during meshing (IM4847).
• Set space sorting tolerance from the Genie to 1.0e-4m, so that sorting in Gamesha becomes independent of database units (IM4105).
• Added check of float (single precision) numeric range on numbers written to FEM file, an error is produced if numbers written is > 1.e+38 (IM4830).
• Increased maximum number of pile diameters for soil curve generation to 15, to be consistent with limitation in Splice (IM4747).

Plate capacity checks

• Corrected naming (indexing) of capacity panels for CSR Bulk , that was not consistent. (IM4750)
• Corrected problem where reducing panel size increased linearised stresses for CSR Bulk. (IM4749)

Frame capacity checks

• Flooded not accounted for in NORSOK N-004. (IM4708)
• Calculation of torsion ufH3 for box sections for API WSD. (IM4669)

Reporting.

• Load combination query in browser should display phase shift in degrees (not radians) . (IM4748)

Export/import

• Optional xml attributes were not implemented correctly. They could have gotten random values if the attribute was not present in the xml. (IM4657)
• Wrong magnitude of point loads transfer between Sacs and Genie (IM4778)
• Conversion of section names while model importing from Sacs to Genie (IM4780).
• Clean JS with T profile represented as Unsym I section would not be read back into Genie, but doing a more tolerant check on section dimensions removes the problem with numerical inaccurcies on the FEM file and clean JS (IM4870 ).
• The unit for Mesh density not be recorded in XML file, corrected so that the mesh density now will be properly converted when importing to a workspace with different database units than the one where the XML file was created (IM4772).
• Error in import of rule loads xml (support curves - rigid link plane) (IM4868)
• Edit of PolyCurves did not display the actual edited curve correctly. Only the first segment was displayed.
• Weight report item names are cleaned to make legal JS names when imported from CSV or XML files.

a) time stamp of exported mesh and mesh used in analysis

b) superelement number

c) number of nodes in superelement

d)number of elements in superelement

Import FEM

XML export / import

• XML export/import of rules meshing and rules tolerances added.

• Deleting geometry that is not used by concepts (unreferenced geometry) on import

Bug Fixes

Modelling

• Corrected problem during a call to HealStructure, where very short beams can in some cases be eliminated due to the fact that they collapse into a point. (IM4239)
  
  
• A message is now given if user tries to create/modify lineload (or 'Beam' load) with conciding endpoints, resulting in a zero extent footprint. (IM4430)
  
  
• Divide of plate using plane took extremely long time, >30 min. This has now been improved significantly. (IM4254)
  
  
• Corrected problem with Apply button in Mesh Property dialog being disabled without specifying growth rate. (IM4138)
  
  
• Corrected crash in joint modelling functionality that occured sometimes when calling autoCan repeatedly on a joint. ( IM4257 )
  
  
• Corrected problem with Model containing wires (i.e. beams not fully connected to plates ) becomes invalid when creating compartments. ( IM4216 )
  
  
• Corrected JS interpreter declaration scope when calling member functions and constructors of a custom javascript class. ( IM4222 )

• Classification of ACIS curves as straight is reimplemented as it classified certain spline curves as being straight. ( IM4153 )

Loads

• When a plate is divided, split or exploded, it now notifies relevant compartments and updates the local compartment load to be copied to all new plates.

• The following line: 10m*sin(30); caused crash. This is because “sin” was interpreted as the unit s*in (IM4341)

• Corrected error in Javascript line load descriptions using units, these were incorrectly translated to a vector of ForcePerArea in stead of a vector of ForcePerLength (IM4338)

• Corrected problem where loads were not properly copied when doing a mirror. ( IM4267 )

Meshing/analysis

• Crash during meshing for huge CSR Bulk model with many loadcases - corrected so that each loadcase is now written to FEM after mesh generation, resulting in improved memory efficiency. (IM4258)

• Warp correction ( - added user option from GUI on Linear Sestra Run dialog - added user option from JS - changed default to enabled ). (IM4304)

• ORDER=3 in SOLM card on Sestra.inp may cause problems ( - no user option from JS yet - changed default to ORDER=0 ) (IM4292) . This option refers to equation solving, see Sestra user documentation for more details.

• Corrected failure to create legal superelemet analysis if first level superelement number is different from 1. Note that when doing pile-soil analysis the number still must be 1 dur to limitation in Splice ( IM4258 )

Capacity checks

• Color code for code checks is now updated when switching context (loadcase and/or run) (IM4390)

• When creating members, sets with 0 beams were automatically selected as subset when no members existed. (IM4456)

• Corrected error where capacity manager (Eurocode3 EN 1993-1-1 2005) does not show worst case the geometry checks for both tension and compression are always performed, independent of current loadcase. This ensures that worst usage factor AND geometry check failure always is shown. (IM4375)
  
  
• Corrected problem where Inherit of codecheck run settings for joint capacity models did not work ( IM4233 )

Result presentation

• Corrected erroneous removal of graphing points in Beam Force/Stress Diagram dialog. (IM4248)

Graphics

• Support index colour for hinges (IM547)

Rotational hinges are labelled with cylinders to indicate the direction of rotation

XML Export/import

• Added warning if mass unit specified is inconsistent with length and force units on XML file imported (IM4424)

• Support for ignoring errors related to invalid references on the xml file. (IM4218)

• Xml import has unexpected failure for plates which overlap exsisting plates. (IM4393)

• Corrected problem where Mesh options were changed during XML export/import ( IM4150 )

• Corrected problem where Feature edges imported using XML import are not registered properly, so that deleting an imported feature edge caused the program to crash. ( IM4155 )

• Created a scheme for postponing modelling operations until after the model has been completely read into GeniE. This is necessary as it is impossible to resolve the sense of a plate until the geometry of the plate has been imported, and the geometry is by default imported later than the actual plate (embedded geometry). ( IM4145 )

• Load factors on load combination in XML import corrected.

Import FEM

• Correction to allow import of FEM node loads with only 3 degrees of freedom (BNLOAD, NDOF=3) (IM4339)
• Correction so that splitting warped plates into 2 triangles gives 2 new named plates.

Reporting

• Removed unexpected jump to next input field in Report dialog. The report title is no longer updated when typing text in the name field. (IM4262)

• Corrected so that repeated values in first column may be shown with ... in HTML and Word XML reports, to improve readability.

· Corrected reporting problem - not possible to perform Save Report when "unicode" username ? (e.g. korean/chinese charactes used in username ) ( IM4212 )

General

• Changed default when reading journal from command line to autodetect version info from input file
