ANYstructure API

The public API is exposed from anystruct.api:

from anystruct.api import CylStru, FlatStru

The API covers flat plate buckling, cylinder/shell buckling, and project file load/save helpers. External spreadsheet-driven DNV PULS execution is not part of the public API in the current release. Use SemiAnalytical S3/U3 or ML-Numeric (PULS based) for the built-in PULS-style flat plate workflows.

See API Examples for complete runnable examples covering flat plates, cylinders, buckling methods, and project file load/save helpers. See Compact API Report Example for a compact manual/report version.

Units and sign conventions

  • Geometry setter dimensions are in millimetres unless a method docstring says otherwise.

  • Material yield and elastic modulus are in MPa.

  • Flat plate pressure and stresses are in MPa, and compression is positive.

  • Cylinder pressure and stresses are in MPa, and compression is negative.

  • Cylinder force input uses Nsd/Qsd in kN and Msd/Tsd in kNm.

Flat Plate API

Supported domains:

  • Flat plate, unstiffened

  • Flat plate, stiffened

  • Flat plate, stiffened with girder

Supported buckling methods:

  • DNV-RP-C201 - prescriptive

  • SemiAnalytical S3/U3

  • ML-Numeric (PULS based)

DNV-RP-C201 - prescriptive returns the legacy nested result dictionary with Plate, Stiffener, Girder, and Local buckling entries where applicable. SemiAnalytical S3/U3 and ML-Numeric (PULS based) return a method result dictionary with buckling UF, ultimate UF, raw UF values, validity, and selected UF fields.

Current flat plate setters and result helpers:

set_plate_geometry

Cylinder API

Supported domains:

  • Longitudinal Stiffened shell

  • Longitudinal Stiffened panel

  • Ring Stiffened shell

  • Ring Stiffened panel

  • Orthogonally Stiffened shell

  • Unstiffened conical shell

Shell domains use force input mode internally; panel domains use stress input mode internally. The API exposes both set_stresses and set_forces for cylinders. Configure shell geometry and the relevant stiffener/ring objects before using force input, because forces are converted to stress from the current geometry. The conical shell domain uses set_conical_shell_geometry and set_conical_forces.
