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.

  1. Bugs fixed in version 3.1.1
  2. Enhancements in version 3.1.1
  3. Changes for VisIt developers in version 3.1.1

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

  • Updated the mfem library to version 4.0.
  • Added host profiles for Leibniz Supercomputing Centre.
  • Enhanced the FFP database plugin and enhanced to use libstripack when it is available, either installed in VisIt’s lib dir or the path specified via the VISIT_FFP_STRIPACK_PATH environment variable.
  • 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.
