@john-science we are still debugging some issues when loading from a database and the treatment of updateAxialMesh. @onufer will update this once we have resolved those issues and the PR will be ready.

[jakehader]

@john-science - The changes here are good and help us get DB loading operational. There are a lot of complexities with the mesh treatment at different loading conditions (from settings/blueprints or from a database) that we need to resolve throughout the code base. This is a good first step and patch for the on-going work here, but @albeanth and I will work together on prioritizing the issues more globally and then proposing an "ARMI mesh refactor/clean-up" project that will help us to get better integration testing for the framework and unit testing on the various ways we can initialize a system model.

I will leave this up to you or @onufer to Squash and Merge, as I don't want to jump ahead without your review and making sure that it doesn't have some impacts on the current in-progress PRs.

@jakehader Also, Tony and I were talking yesterday and it sounds like there has not been much/any testing of the new detailed axial expansion features when it comes to reading from a Database. So I think that needs to be tested at some point, wherever that fits on the schedule.

I have been loading axially-expanded cores from the DB. I haven't looked in super detail at it, but it appears to be working in the sense that the assemblies are expanded.

This is not with detailedAxialExpansion.
