Elements¶
Element support and maturity are separate. The published 0.2.8 consolidated registry remains authoritative for its 46 recorded element-analysis combinations; 0.2.10 nonlinear evidence and its limitations are reported separately and remain relevant in 0.2.11.
| Element family | 0.2.8 bounded scope | 0.2.10 nonlinear evidence / limitation |
|---|---|---|
| TET4 | Recorded linear and small-strain J2 routes | Selected Total-Lagrangian StVK static audit (GO_WITH_LIMITATIONS, no maturity promotion); selected coupled static evidence. |
| TET10 | Recorded linear and small-strain J2 routes | Bounded extension/coupled evidence; no blanket geometric or corotational-J2 promotion. |
| HEX8 | Recorded linear and small-strain J2 routes | Corotational J2 has bounded Owner acceptance; selected Total-Lagrangian audit; coupled evidence. Each scope has separate limitations. |
| HEX20 | Recorded linear and small-strain J2 routes | Bounded extension/coupled evidence; not a general finite-strain or contact qualification. |
| WEDGE6 | Bounded static and modal scopes | No nonlinear maturity claim from the cited development-cycle evidence. |
| MITC3/MITC4, BEAM2 and discrete entities | Route-dependent; see their records | Do not infer nonlinear support from linear availability. |
| WEDGE15 | Not supported | No claim. |
| PYRAMID5 | Internal / RESEARCH_ONLY |
Not a public supported-element claim. |
HEX8-SRI is a separate experimental capability; it is not a blanket claim for HEX8R, B-bar, or hourglass-control formulations. Higher-order families may have narrower nonlinear evidence than their linear registry coverage.
The 0.2.11 rotating extension uses only a straight, collinear BEAM2 shaft
with circular isotropic sections and centered rigid axisymmetric disks.
It is EXPERIMENTAL; legacy beam or shell support does not extend that
scope to shells, solid rotor meshes, eccentric disks or distributed shaft
gyroscopy. Each disk owns its mass and gyroscopic term; duplicate generic
disk mass at the same node is rejected. See rotating modal
and Campbell.
Before selecting an element, check geometry quality, orientation, expected deformation, loading, material model, and required output. Refinement cannot repair an invalid Jacobian or an unsupported kinematic/constitutive route.
See the analysis map, capability matrix, and known limitations. The original 0.2.8 consolidated registry is not silently re-scored by this page.
