Release Notes for VisIt 3.1.1

Welcome to VisIt's release notes page. This page describes the important enhancements and bug-fixes that were added to this release.

Bugs fixed in version 3.1.1

  • Corrected a bug where certain types of mili datasets would cause unexpected crashes.
  • Corrected a bug where the Data level comparison wizard would always enter zero for the simulation cycle.
  • Corrected a bug where zone pick highlights were incorrect after transforms were applied.
  • Corrected a bug summing mesh_quality/volume in a sub-material setting.
  • Corrected a bug where VisIt crashes on start-up on some Windows systems when the system OpenGL version is too old. VisIt now determines the OpenGL version during the installation process and uses Mesa3D as a drop-in replacement if needed, with a warning on the installer pages to notify the user that the graphics cards / drivers should be updated.
  • Corrected a bug importing remote profiles from a Windows system.
  • Corrected a bug performing QueryOverTime with plots involving operator-created expressions.
  • Corrected a bug where VisIt would only display a black window when displaying on a Windows system running the XWin-32 X Server.
  • Corrected a bug with external surfaces not display with Pseudocolor Plots when the centering is changed from original centering.
  • Corrected a bug where makemili_driver was not properly installed, making it unusable.

Enhancements in version 3.1.1

  • Removed the host profile for Lawrence Livermore National Laboratory's rzuseq system.
  • Removed the use of the rzgw gateway from all the Lawrence Livermore National Laboratory's RZ host profiles.

Changes for VisIt developers in version 3.1.1

  • Updated build_visit to work on macOS 10.14.
  • Enhanced build_visit to download the visit source code and third party libraries from GitHub instead of NERSC."
  • Updated build_visit to allow the user to disable the building of Sphinx. To disable building Sphinx specify "--no-sphinx".
  • Enhanced build_visit to also package VisIt into a tar file after building it so that VisIt is ready to install.
  • Enhanced build_visit to also build the VisIt manuals when building VisIt.
  • Enhanced build_visit to add checksums for the VisIt source tar file when writing a unified file. It assumes that the tar file containing the VisIt source file is in the current directory. If any errors are encountered and it can't add the checksums a warning is printed.
