Release Notes for GASP v4.3.1

Date of Release: March 2007

VERSION 4.3.1 NEW FEATURES

• Support for flow solver and GUI on Windows XP platforms
• Added rotating frame source terms. Allows a fixed grid simulation of a rotating frame. This also adds time metrics and a bc velocity. The GUI has a rotation src tab in the physical model. Added a user specified wall velocity based on a rotation and axis.
• Added periodic bcs with a more general formulation that supports a rotated frame. User now inputs rotation angle and axis for a periodic bc.
• Added to the output option the ability to do output during a time accurate run based on a physical time increment (not just time step)

BUG FIXES AND CORRECTIONS

• Added check for xml file to exist in the wrapper
• Bug fix when parsing relative paths for the thermo-chemistry database location
• Added checks to flow solver to see if the grid or solution file exists (since both are required).
• Bug fix to allow proper function of command line based replace grid and replace soln operations due to improper checking of file version.
• Fixed a bug in initializing thermo-chemistry database when lasing source terms are used
• New versions of GLib cause memory faults when new memory allocation scheme is used. Default back to old allocation scheme in this case.
• When the flow-solver is run, perform a check to make sure the xml file exists in order to avoid cryptic error messages.
• Changed how the system dtMin info is written to the aux file. Before it only wrote the data on the active run defn.
• Set widget sensitivity in the time information window correctly
• In the particle tracking algorithm, limit the time step growth for the error adapting Runge-Kutta algorithm to an order of magnitude for stability.
• Bug fix to Runge-Kutta and turbulence models using TKE (the primitive variable for pressure was not computed correctly)
• Menter SST: Coefficient fixed; affects eddy viscosity at small omega
• Define abort() to be exit(0) for windows. windows doesn't handle abort gracefully. It tries to rerun the application and produces numerous pop-up messages.
• Win32 does not properly handle logical links. When running time accurate simulations on Win32, copy the grid file instead of trying to make a logical link
• Bug fix for using aux zones during MPI solution output. Caused MPI lockup when trying to compute output on zones not currently being run.
• Improve functionality, operation of zipper grids for chimera post-processing.
• Changed WENO limiting to include (u,v,w) and changed full-flux ql,qr
• New default settings for WENO in the GUI Default settings should produce more robust results
• Correction to higher order tangency BC. Do not allow negative pressure
• Correction in the dq update (loop parmeters corrected for dq limiting)
• Bug fix for crash upon I/O of Chimera hole cutting override nodes
• Added a button to the pointwise data that allows the user to reverse the data in the table in case the data was ordered differently from the pointwise table. Change the turbulence limiter default from 1 to 10,000.
• More soln/grid file fixes for runge kutta.
• Default output file for particles set to (x,y,z,time,u,v,w,temp,mass,dia)
• Fixed bug in in parallal computation of Chimera coefficients from flow solver.
• k-w SST bug: value for sig_k1 corrected
• Fix bug that caused MPI to stall when performing solution reinitialization
• Improve clarity of particle output
• Initial particle temperature set to 273 as default
• Bug fix for calculation of lewis curve fit based transport properties for display in front end. Note that the flow solver correclty computes these values.
• New output options for particle tracking. GUI reorganized for particles. Particles tab in Run Definition is not shown unless particles used.
• Bug fix for MPI based hole cutting from flow solver.
• Bug fix to correctly identify whether or not a solution has Chimera.
• Bug fix for Large File Support for 32 bit archs
• Bug Fix for writing out Proj flag in chimera setup.
• isDonor bug fix for overriding donor zones
• Cleaned up StableResonator routines and added OPD calculation for chemical laser calculations
• Updated/fixed general bugs in thermo-chemistry database
• Bug fix in calcuation of a global dt based upon constant CFL.
• Bug for InjectParticles for multi-proc and decomped, or multi-surface
• Updated particle tracking for steady state flows and fixed an MPI bug with the injection
• Updated liquid Frame Inputs in database manager. Added option to do artificial ignition to GUI. Updated particle tracking (non-dimensional supported, use of solid particles, added injection options). Added additional checks upon GUI exit and save. Misc bug fixes.
• Added error checking for Sweep values upon exit or save of GUI
• bug fix: doing general interp soln did not force a write on the solution
