How bhatthiman/noja works

NoJA is currently a command-line tool for validating engineering CSV inputs and generating shell-to-nozzle CAD geometry; the README describes finite-element evaluation as the broader goal, but the documented working capability is geometry generation. The workflow validates inputs, creates a timestamped run folder, copies the job CSV, builds the shell/nozzle model, and exports STEP and BREP files. Materials are checked for required columns, but the shown runtime does not use material properties or perform stress analysis. RF-pad geometry is represented as an optional model feature; source excerpts do not show its exact dispatch logic.
