Pre-processing#
Pre-processing is where you describe the physics. Given a mesh, you
stamp element types, materials, real constants, and boundary
conditions onto it — the output is a Model that
can produce global sparse \(K\) and \(M\).
The Model
How to build a Model from a pyvista grid
or from scratch with MAPDL-style verbs.
Element library
The catalogue of registered elements, how to pick one, and the per-element theory / KEYOPT reference.
Materials
The MP command, supported property names, and the
MaterialProperty enum.
Real constants
Per-element geometric data: shell thickness, beam cross-section, spring constants, point masses.
Boundary conditions and loads
Model.d() for Dirichlet, Model.f() for nodal forces /
moments, and the prescribed= argument on the solvers.
