MRST 2024b is the 30th release of the Matlab Reservoir Simulation Toolbox. More information about the software can be found at http://www.mrst.no. Full release notes can be found here: https://www.sintef.no/projectweb/mrst/download/release-notes-for-mrst-2024b/ The new release comes with some small improvements in functionality, minor bug fixes and changes to maintain compatibility with newer versions of MATLAB. The largest change in this release is organisational, as MRST has now been fully migrated to GitHub as a single, easy to clone repository that contains everything from the release: https://github.com/SINTEF-AppliedCompSci/MRST We note that some users have reported issues in the form of warnings and errors for some modules with MATLAB 2024a/b. These issues are reported for modules streamlines and heterogeneity and parts of the corner-point processing. We believe that these issues are resolved in the latest release, but please let us know if you encounter any issues.
