VisIt 2.1.1 Release Notes
Welcome to VisIt's release notes page. Release 2.1.1 is primarily a bug fix release to release 2.1. It fixes additional bugs in release 2.1. Look here to see a complete list of changes in release 2.1.
Bugs fixed in version 2.1.1
- When you save a window using the Screen ratio option, the image should match what you see on the screen much better.
- Saving movies using "movie templates" is now fixed.
- Clicking Print in the Print dialog now prints on all platforms.
- The molecule plot now correctly uses 'sphere imposters' in scalable
rendering mode.
- The FVCOM reader can group files again.
- The Tecplot reader understands additions to the Tecplot ASCII format, such as comments, NODES/ELEMENTS as aliases for N/E, and complex VARLOCATION specifications.
- The Tecplot writer adds extra spaces between elements to avoid cases where field widths were not sufficient to prevent overlap.
- The ThreeSlice operator now correctly handles data with mixed mesh types, such as unstructured and structured in different domains.
- The H5Part reader no erroneously longer assumes a timestep of 0 for some operations.
- The 3D view axis scaling behavior has received some usability improvements.
- The POV-Ray exporter now avoids POV-Ray errors on degenerate geometry.
- The -viewer_geometry argument works again, letting you tell VisIt where to place the viewer windows.
- Position independent code is forced when building Mesa, as a workaround for build that appeared on 32bit
SELinux-enabled systems.
- The streamline plot:
- now works properly on 2D curvilinear meshes.
- now updates its legend properly when you change color tables.
- no longer suffers from memory corruption issues like those described in
issue 368.
- no longer crashes when applied to an empty data set.
- handles sample densities more robustly when going from the CLI to the gui.
- now is more robust when cropping away portions of a streamline for animations. 4 defects were resolved and the user interface was improved.
- The resample operator now correctly preserves vector data for all mesh types. (Previously only rectilinear and AMR worked correctly.)
- The uniform placement option for the vector plot now:
- works with the save window feature and in scalable rendering mode.
- warns you when you have tried a configuration it can't succeed with (e.g. uniform placement over a surface in 3D).
- does not produce gigantic vectors in regions where there is no data.
- no longer scales your data when you look at non-rectilinear data.
- The Reverse, Turn all on, Turn all off buttons in the Subset window now take effect immediately when the Auto apply setting is enabled.
- The volume plot was incorrectly restricting the maximum number of samples per ray when ray casting. This restriction has been lifted.
- The DataBinning operator now can be used in conjunction with the Contour plot and the Volume plot.
- Save Session and Save Settings will now work correctly for the DataBinning, AMRStitchCell,
DeformSphereGlyph, Delaunay, and Edge operators.
- The PersistentParticles operator now works in conjunction with Selections for all data. (It previously
only worked with FastBit data.)
- Banks can now be correctly specified on Argonne's Eureka machine.
- An indexing problem for the SetWindowMode in the Python interface was corrected.
- The Label plot can now set text heights that are fractional percents. Meaning 1.5% is now possible, where only 1% and 2% were possible through the GUI previously.
- A bug was fixed that prevented saving movies with old session files.
- Expressions that extract vectors from tensor data now work correctly for 2D data.
- Making movies once again can obtain the engine launch parameters from a session file. This fixes the movie-making case where you want to use a new instance of VisIt or if you want VisIt to tell you the command to run.
- Quoting for string data in saved settings has been eliminated except for strings that contain spaces. This more closely matches VisIt's old behavior, improving compatibility with older versions of VisIt.
- Cracks Clipper operator works again.
- The embedded viewer example program now works on Windows.
- The Windows installer now checks for previous versions of VisIt in the PATH environment variable, and removes them if user so chooses.
- SimV2 can better deal with 2-element arrays when setting real indices and base indices for rectilinear meshes.
- The default number of cores per node to use was changed from 8 to 16 for the parallel interactive pdebug profile on hera.
- The new RenamePickLabel function has been changed so it can repeatedly use the pick letter as the old pick text.
- A Mac-specific bug was fixed where the Threshold operator was not correctly inputting ranges from the window in all occasions.
- A Mac-specific bug was fixed where legend annotation attributes were not correctly inputting labels in all occasions.
- A bug with passing arbitrary arguments to Python Queries was fixed.
- Versioned releases of build_visit are now tied to the proper release tag in svn mode.
- A parallel engine bug with patch selection for Silo AMR data sets was resolved.
- Windows version can save mpeg encoded movies again.
- A Windows-specific bug with Restore Session was fixed.
- The DDCDM reader works properly again in parallel.
Enhancements in version 2.1.1
- The -o command line option, and OpenDatabase Python command, to open files with a specific database reader plugin no longer requires a plugin version. For example, visit -o myvtkfile,VTK now works as expected.
- Host profiles were added for the new LLNL machines aztec, edge and inca.
- Host profiles were added for Argonne's MCS machines.
- Performance of vector plots with lots of zero-magnitude data has been improved.
- VisIt's behavior for prompting about whether you want to exit all of VisIt or just the graphical interface has been improved.
