Claude writes the process route with stations, cycle times, breakdown rates and yields, sizes each station from demand, and a discrete event simulation computes every number on screen, from throughput to the bottleneck.
For manufacturing and industrial engineers sketching a new line: click a station, change its cycle time or buffer, and watch where the bottleneck moves.
Davy Demeyer gives Claude the batch size, batches per day and one reactor tank, points it at the Acceleer MCP server, and lets it run for a couple of hours before a first design review. The engineer's job moves to the review; he is taking a limited number of paid proofs of concept for chemical, pharma and food plants.
The costly mistake is usually not a bad meter but a flow computer running on a stale gas composition. Their line is that an unvalidated model output should never change a billed quantity.
An agent skill and MCP toolkit that builds native SLDPRT and SLDDRW files, exports a PDF and rereads dimensions. Its stated rule is that a tool call succeeding is not the same as the task being done. The README is mostly Chinese.
For mechanical engineers: a worked path from a plain request to a checked part and drawing, with evidence kept, which matters more than speed when the part goes to a shop.
