Release Notes for GASP v5.0.2
Date of Release: February 2010
New Features Added
-
Implemented an automated time step-limiting algorithm to improve
the robustness of time integration. This new algorithm monitors the
magnitude of change in the solution at each time step, and
locally reduces the time step in order to keep the change to a
user specified amount.
-
Added preliminary support for monitoring binary file change within the GUI.
Refresh graphics in GUI when solution file changes due to flow solver.
-
Support exporting both PNG and TIFF formats when outputting snapshots.
If the suffix is .tif, or .tiff, then write a TIFF format, if it is .png, then
write a PNG file.
-
Reformulated the venkat limiter for the unstructured flow solver to include local
non-dimensionionalization of the limited variables in the normalizaton of the epsilon
parameter used within the limiter. This change improves consistency in applying limiter
when non-dimensionalized values are far from unity.
-
Always write the CFL and cycle number to the xml file. This change makes it easier to
find these values in the .xml when making changes to file with a text editor.
-
Added support for using Metis 5
-
Improve diagnostic messages for binary file error handling.
These messages will assist AeroSoft customer support in diagnosing
I/O related errors.
Bug Fixes
-
Flow Solver - General:
-
Correction to Air/Carbon surface chemistry BC's (51,52).
Ensured that mass flow at wall is zero.
-
Bug fixed for MPI output of Tecplot Bin file
-
Flow Solver - Structured
-
Bug fix for WENO implicit jacobians
-
Flow Solver - Unstructured:
-
Added a second method for computing the viscous gradient at a face.
This option is now in the GUI.
-
The correct viscous gradient is now used in output calculations
-
Improve robustness of global solution limiting procedures
-
Add routines to complete Menter's Transition model
Added an exponential decay term when using the global
catastrophic limiting of Pmin (slows the update as q approaches Pmin)
-
Bug fix for FV-UNS soln file output.
-
Bug fix for tecplot zone unstructured connectivity data (file output)
GUI:
-
Newer linux distributions did not properly display some button text
-
Improve clarity of k-epsilon model names in the GUI
-
Improve clarity of unstructured gradient methods
-
Venkat limiter in unstructured section was incorrectly named Spekreijse Venkat.
-
Bug fix for unstructured CGNS import with only node data (building
face data had a bug for multiple cell types)
-
Added a pop-up window when selecting Menter's transition model to
inform the user that it is a 2-eqn model only for SST
-
Updated flux output names (there was an extra space in the
varName which made the var unrecognized)
-
Bug fix in file output handle drop. Dropping a zone folder into
an existing output node caused file corruption
-
Bug fix: Pointwise x,y,z data exported to file was off by 1/4.
-
Unstructured memory leaks fixed for pointwise
-
Improved Unstructured grid import for FV-UNS grids and added better
warnings for the user
