Description
The Modelica.Fluid.Examples.AST_BatchPlant.BatchPlant_StandardWater model fails because of numerical issues.
Deeper analysis reveals that the model is quite ill-conditioned. I opened PR #2925 on the MSL repo with a fix to address this issue.
Once accepted into the MSL master branch, this should then be patched onto MSL 3.2.3/maintenance, and used to update the version of MSL we ship with OMC.

PR #2925 was eventually merged in 4.0.0, but it required a number of changes in the library that were not easy to port back to 3.2.3 maintenance. We should try to see if some simple fixes (e.g. using a simpler fluid model) can improve the situation.

I guess this will eventually be fixed in 2.0.0
