The ecosystem

How the parts fit together: what comes in, which tools and solvers handle it, and how CompliSpec turns results into a requirement check.

Step by step

  1. Inputs: CAD from Onshape, STEP or STL; field markups and site notes; or an AI design chat that becomes a 3D model.
  2. KJLabs Simulators: the FEA pipeline, 3D duct designer, airflow and loss simulator, and the fan and cyclone quick-look.
  3. Open-source solvers: four structural codes and two CFD codes run headless, each validated on a reference case first.
  4. CompliSpec: results and duct layouts are checked against requirements stored as code, one jurisdiction at a time.
  5. Three honest outcomes: a pass or fail with its source, an inspection checklist for procedural rules, or not computable with the missing inputs named.
