New Features

• Added an option to print license information from the command line. This is done using: gasp --license
• Added number density to the list of available variables in the user defined variables dialog for output and visualization.
• Added velocity, pressure, and density gradients to the output variables (Note: this addition resulted in a change to the units.txt file which may produce warning messages).
• The residual output now displays x,y,z data for the maximum residual when running unstructured.
• Added a "Display Grid Info" option to the "Zones" -> "Grid Mgt" window in the GUI.
• Added a new feature to create a gas species from a mixture of species in the database GUI.
• Updated the CFL ramp to include linear, log, and residual based ramping. This is a new option in the time integration.
• Implemented Modified Fick's law in conjunction with the use of Lennard Jones integrals to compute collision cross section integrals. This supports a new option for modeling species diffusion.
• Added print statements to output concerning solution initialization upon solver execution.
• Added support for copying information from a "Visualization" folder to a new "File Output" folder using drag-n-drop within the GUI.

Bug Fixes

• Fixed a bug involving the archive increment number when restoring an archive and restarting. After restart, the next archive increment was wrong. Fixed a bug involving archive recovery in GUI.
• Operator splitting can now be used with Dual-Time stepping and unstructured grids. Before, this was an invalid operation and resulted in an error.
• Real stoichiometric coefficients in reactions can now be used with operator splitting, as well as the global limiting options.
• Fixed a bug in the non-dimensionalization of pointwise data for solid thermodynamics.
• Fixed a bug when moving data nodes within a vtk input folder or moving from one folder to another.

Misc Items

• Increased GUI display precision for the Navier-Stokes QSpec parameters.
• Added an input flag (from the .gsp file only) to dump all NaN locations if requested. Save GUI with "Include All XML" and then search input deck file for DumpAllNan.
• The GUI input for non-equilibrium vibrational species now checks for the max possible value allowed.
• Added a check to the thermo-chemistry database to warn if the electron, e- is not the last species in the list within a given model. This is the current policy when using the electron species.
• Changed the Jacobian option for the DVODE solver to be numerical instead of analytical.
• The GUI highlight node feature is off by default. To use it run the GUI with --highlight.
