Procedure::Buckle {modes, shift}: the step's loads as a linear preload, K_σ from its stresses,
and (K + λ K_σ) φ = 0 by block Lanczos in the K inner product: K⁻¹(−K_σ) on Cholesky without a
shift, the buckling transformation (K + σ K_σ)⁻¹ K on LDLᵀ with one, whose inertia counts the
load factors below σ (Grimes–Lewis–Simon 1994). Lanczos gains an operand and an eigenvalue map
(defaults keep frequency steps bit for bit) and reports converged negative eigenvalues. Results
are frequency results with a `buckling` part; modes display with their load factor.
solve.buckle (in the Static drop-down); Abaqus *BUCKLE, Nastran SOL 105 and LS-DYNA refuse it by
name. Euler columns of hex20 within 0.18 % of Engesser's load.

# Features
|
||
|
||
Generated from the capability catalogue (`crates/engine/src/catalogue.rs`) by
|
||
`cargo run -p fieldcraft-cli -- features > docs/features.md`; a test fails when it is out of date.
|
||
Every entry is a toolbar button. **Ready** entries run their command; **coming soon** entries are
|
||
shown greyed with the roadmap milestone that brings them (ROADMAP.md). Scripts, the command line,
|
||
the control channel and AI agents over MCP (docs/mcp.md) run the same commands.
|
||
|
||
59 ready, 45 coming soon.
