LinearSolver
=============

The ``LinearSolver`` performs a single linear solve for the global displacement
vector given the assembled tangent stiffness and external force. It then
computes derived quantities and terminates the analysis.

Overview
--------

Solver type: ``LinearSolver``

- Method: single-step linear solution ``K a = f_ext``
- Outputs: updates state, computes ``Dstate``, internal forces, commits history
- Termination: deactivates model after the single solve

Parameters
