Build an IFC Model Code_Aster Structural Simulation Prep Dispatcher

Analyze IFC structural models using ifc2ca conventions to prepare finite element analysis inputs. Identify disconnected structural nodes and map structural curve members before simulation execution.

Structural engineering consultant

Parse structural IFC files containing IfcStructuralCurveMember elements.

Inspect node connectivity using simulated ifc2ca utility logic.

Synthesize material structural properties into Code_Aster command blocks.

Generate pre-flight simulation reports for engineering review.

Engineering pre-processor workbench with 3D wireframe preview, node connectivity table, and text export.

Use open-source sample structural IFC models from buildingSMART or mock IFC structural test files via IfcOpenShell. Starter examples below are synthetic. They are not downloaded records.

IfcOpenShell Applies the ifc2ca utility mentioned in the IfcOpenShell repository table for converting IFC structural models to Code_Aster.

langgraph, fastapi. LangGraph manages the multi-stage structural validation pipeline from model parsing to mesh syntax generation. Hosted reasoning model for mapping material mechanics strings to standard Code_Aster commands.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Flags unlinked structural connection nodes prior to simulation deck generation.

Outputs structured Code_Aster command strings with valid geometric constraints.

Simulates file write operations to sandbox directory.

Outputs pre-flight simulation configurations only; does not perform physical stress calculations or load clearances. Use mock external writes. Require human review before any real deployment.
