These release notes include all features, updates, extensions and bug-fixes included in ESABASE2 since release 2.0.

Framework:
———————

• BAS Import:
  • REMOVE is now supported.
  • A progress bar was added to display progress information during the import.
• Geometry Editor:
  • Material handling has been added:
    • The Geometry Wizards provide a new wizard page to define materials and assign them to surfaces.
    • All materials are stored within a library which can be extended by user-defined materials.

New applications:
———————————-

Sunlight:

• Capability to analyse the incident energy
  • of the Sun,
  • of planet albedo and
  • of planet infrared radiation

on a geometry, and its absorption by the surfaces of the geometry.

• Consideration of shadowing, reflection and transmission effects.
• Additional material attributes (for absorptivity, reflection and transmission) are provided via the material editor.
• Sunlight provides geometrical analysis only.

COMOVA (COntamination Modelling Outgassing & Vent Analysis Tool):

• Developed by ONERA and HTS in 2000.
• Modelling of molecular contamination on spacecraft’s external surfaces.
• Including solvers for geometric analysis and ground test.
• Additional Geometry Editor page for COMOVA specific geometry attributes.

Atmosphere/Ionosphere:

• Capability to analyse the flux of several gas types (atoms and ions) on an orbiting geometry (up to 2000 km altitude).
• Several atmosphere and ionosphere models included.
• Consideration of wind effects (wind models).
• Geometrical and non-geometrical analysis capabilities (similar to the Debris application).
• Display of atmosphere model specific parameters.

• New atmosphere models: JB2006 and NRLMSISE00.
• New ionosphere model: IRI2007.
• Wind model: HWM93 (Atmosphere and Ionosphere applications).

Applications:
————————

• All applications now provide a printing option for listing files.
• The result editors have been extended by an option to save the 3D view as JPEG or PNG.

Bug fixes:
——————

• 20 smaller bugs have been fixed.

Framework:

• BAS Import:
  • The following shapes/dummyshapes are now supported:
    • CIRCLE
    • CONNECT
    • FACET
    • PLATE
    • POINT
    • PRISM
    • SURFACE
  • Support of the COPY and the MIRROR command
• STEP Import:
  • Re-design of the import process
  • It is now possible to define more parameters for the NetGen mesher
• Geometry Editor:
  • Added Geometry Wizards for:
    • Surface
    • Plate
    • Prism
  • It is now possible to define Surface Nodes
  • It is now possible to add materials to surfaces
• Introduced a logging mechanism
• A new version of the Software User Manual (SUM) is available

Debris Module:

• Re-design of the Debris Editor
• Removed NASA96 Debris Model
• Removed Cour-Palais Meteoroid Model
• Added MASTER 2005 Debris Model
• Added MEM Meteoroid Model
• Divine-Staubach meteoroid model implementation changed from MASTER 2001 to MASTER 2005
• Re-design of the listing file output to achieve better readability
• Introduced a “Slim Result” option for analyses:
  • It is now possible to turn off the generation of 3D results.
  • This reduces memory consumption and shortens the runtime of an analysis.
• 2D results:
  • 2D plots of flux vs. velocity distributions included in the Debris result files
  • 2D mission average plots are now available for all models where these distributions are available

Software-Upgrades:

• Upgrade to OCC 6.3
• Upgrade to Java 1.6.0_06
• Upgrade to Eclipse 3.3.1.1
• Upgrade to JFreeReport (now pentaho) 0.8.9
• Switched from VisAD to JFreeChart 1.0.10 for 2D visulisation
• Upgrade to NetGen 4.5

Operating Systems:

• ESABASE2 now supports Windows Vista
