What it can do

  • Writes geometry through the History List and reads results through query macros, returning CST's own error text when a step fails.
  • Includes a substrate and metal material table, one-step microstrip and coax-probe feeds, and far-field metrics such as gain, HPBW, front-to-back ratio, axial ratio and efficiency.
  • Runs server-side parameter sweeps and CST's built-in optimizers, and checks the model before solving for missing ports, monitors and overlapping solids.
  • Ships three skills (cst-design, cst-search, cst-stackup) and a design-card library shared with the author's HFSS server.

Limitations

  • Can't take over a CST window that is already running; it starts its own CST process.
  • A solve can't be stopped mid-run, and only one project is driven at a time.
  • Design Studio circuit projects aren't supported.
  • Floquet ports, plane waves and lumped elements have no dedicated tools yet and go through raw VBA.
