apeGmsh

Use whenever the user is working with apeGmsh — the structural-FEM wrapper around Gmsh with OpenSees integration. Triggers on building FEM models from CAD/STEP imports, Part-based assembly workflows, composite-based geometry/mesh/constraint APIs (g.model, g.mesh, g.physical, g.constraints, etc.), the apeSees(fem) OpenSees bridge with typed primitives and automatic MP-constraint emission, staged analysis (ops.stage), loads/masses/constraints resolution into the FEMData broker, native model.h5 persistence (FEMData.to_h5/from_h5, save_to=/g.save(), apeGmsh.from_h5), model composition (g.compose), post-processing OpenSees output via Results (from_native/from_mpco/from_recorders) with the interactive and web viewers (results.viewer / results.show_web), and exporting models to OpenSees Tcl or openseespy scripts. Covers apeGmsh's own abstractions on top of Gmsh and OpenSees. For raw gmsh API questions see the gmsh-structural skill; for raw OpenSees analysis commands see opensees-expert; for FEM theory first principl

apeGmsh is a Gmsh wrapper for structural FEM with first-class OpenSees integration. Use this skill any time the user is writing, reading, debugging, or reviewing code that imports apeGmsh (``from apeGmsh import apeGmsh`` / ``Part`` / ``FEMData`` / ``Results``) or touches the apeGmsh project at ``C:\Users\nmora\Github\apeGmsh``. Trigger for: building an ``apeGmsh`` session, composing geometry via ``g.model.geometry/boolean/transforms/io/queries``, meshing via ``g.mesh.generation/sizing/field/structured/editing/queries/ partitioning``, labels, physical groups, FEMData broker (``g.mesh.queries.get_fem_data``), multi-part assemblies (``Part`` + ``g.parts``), loads / masses / constraints (``g.loads``, ``g.masses``, ``g.constraints``), per-node ndf (inferred + ``ops.ndf``), the ``apeSees(fem)`` OpenSees bridge with typed primitives, post-processing OpenSees output via ``Results`` (``from_native`` / ``from_mpco`` / ``from_recorders``) and the web/Qt viewers, native ``model.h5`` persistence (``FEMData.to_h5`` / ``fro
