In this PR we implement the Debris Friction sliding law and corresponding testing.
This PR is built on top of #1101.

jeremy-brooks-1 and others added 2 commits February 4, 2026 08:14
Add debris-bed friction slip relation.
Adding two new friction parameters, could set as constants in
albany_input.yaml or read fields from MPAS mesh:
*bulkFrictionCoefficient
*basalDebrisFactor
There are corresponding changes in MPAS interface in MALI-Dev/ES3M
repository.
Note: N0 and u0 are hard-coded, but need to be definable  via YAML file
    (as scalars, not fields)
Add possiblity to set N0 and u0 via input file
Fix parameter logic
Added a test to exercise new sliding law
