Pre-processing
==============

Getting a :class:`~femorph_solver.Model` ready for a solve — loading
meshes, attaching materials, stamping real constants, applying
boundary conditions.

Examples here focus on the **how** of model building.  For the
**what** (element library, material table, BC verbs), see the
:doc:`/user-guide/pre-processing/index`.
