feat: named case-result load combinations with full GUI support
Snapshots the current development tree, headlined by proper load combinations (user request): a reusable LoadCombination entity of weighted completed static-case results (e.g. 1.2xDead + 1.6xLive). - core: LoadCombination/LoadCombinationItem entities, Project integration (lookup, unique ids, reference validation) - services: combinations.py (linear superposition + envelope), exported via services __init__ - commands: undoable Add/Delete/Update for combinations - GUI: Load Combinations manager dialog, Run-dialog evaluation, envelope display in Results panel, Combinations tab in Table dock - tests: unit coverage (validation, math, error paths) + integration superposition check vs a single factored run

"""OpenSees Example 1a. 2D Elastic Cantilever Column.
|
||||
|
||||
OpenSees Wiki:
|
||||
https://opensees.berkeley.edu/wiki/index.php?title=OpenSees_Example_1a._2D_Elastic_Cantilever_Column
|
||||
|
||||
This model keeps the original Example 1a geometry and packages both
|
||||
lateral-load variants into a single OTKO project:
|
||||
|
||||
- Gravity preload in 10 static LoadControl steps
|
||||
- Displacement-controlled static pushover
|
||||
- UniformExcitation ground-motion analysis using ``BM68elc.acc``
|
||||
|
||||
Run from the repository root:
|
||||
|
||||
python examples/ex1a_canti2d.py
|
||||
|
||||
Produces ``examples/ex1a_canti2d.osmodel``.
