GASP: Release Notes

Current GASP Version: 5.3.0

New Features in v5.3.0

  • The GASP physical properties database has been updated. The result is a slight change to the XML based database file. The new version of GASP will still read the older Version 5.2 database files, but the user is encouraged to open older database files in the database GUI and select save. This will convert the older database file to the new file format. The database GUI can now import reactions from Chemkin files with limited support.
  • The database GUI can now be launched from within the GASP GUI. This allows users to more quickly access the database when setting up or using the GUI.
  • GASP now supports coupled solutions between structured and unstructured meshes. Multi-zone grids containing a combination of both grid types (and point-to-point zonal boundaries) is now supported by GASP. Full mesh import can be done via the CGNS grid format or zones can be imported independently.
  • User defined output variables can now be used to represent any pre-defined output variable. This allows users to build output expressions using any of the output variables in GASP. Prior versions of GASP supported a limited set of user defined variables.
  • Global variables are now supported for every integer or real based numeric input. Global variables may also be set up as cycle or time dependent variables.
  • File output can now be sent to CGNS format files. This includes options for the grid, solution, or both.
  • Boundary conditions are now set using a dialog. The new dialog allows the user to filter boundary conditions based on categories, such as inflow, outflow, solid walls, etc. A short description of each BC is also provided.
  • Unique data for boundary conditions has been moved from the QSpec to the Boundary Conditions section. As a result, there is now a BC Data selection in the boundary condition table.
  • A new time integration scheme has been added which is the second order Crank Nicolson method. The set up and application of the scheme is very similar to the Dual-Time Stepping option.
  • A new second order conservative interpolation algorithm has been implemented. This allows the solution from one set of zones to be interpolated to another set in a conservative manner.
  • A new component has been added the GASP solution framework called the Zone Algorithm. The Zone Algorithm operates on a collection of Zones either at user controlled events during the solution process, or from within the GUI. Current Zone Algorithms include structured grid shock fitting, grid adaptation for unstructured grids, and conservative solution interpolation. Note that while some algorithms existed in previous versions of GASP, the unique algorithms have been refactored to derive from a single Zone Algorithm Framework.
