High-order Nodal Fields and Solution Transfer

[mortezah]

This pull request achieves the following

• adds higher order nodal (hierarchic) fields similar to the implementation of MFEM
• adds a regression test for such fields
• updates the solution transfer codes so that these higher order fields are also transferred during adapt
• adds a regression test for higher order solutions transfer

Looks good at first glance. I'll take a closer look tomorrow.

Please add any new source files to the pkg_tribits.cmake files in each directory.

@cwsmith the new source are in the pkg_tribits.cmake

@cwsmith

Do you know when this would be merged? A student I am working with will need these changes for his development.

[cwsmith]

Sorry for the delay. I'll look in about an hour.

@cwsmith thanks for the reviews. I am going to merge this shortly if there are no more issues. Github has a few options

• merge commit
• squash and merge
• rebase and merge

Which one is the suggested method?

[cwsmith]

You're welcome.

The answer depends on what history (sequence of commits) you want to exist in develop after the merge.

• merge commitwill add the sequence of commits from the PR to develop + a 'merge' commit.
• squash and merge will combine ('squash') all the commits from this PR into a new commit and add it and a 'merge' commit into develop.
• rebase and merge will squash the commits and add that commit onto develop

This appears like a decent, deeper, explanation of the differences: https://rietta.com/blog/github-merge-types/

@cwsmith thanks.

I will do the merge commit, since I will need to refer to some of the commits (for code style and development purposes) when I work with the students.
