Academic pilot

You set the level, not the student.

An instructor picks one of three levels for a course. The level is configuration, so a student rewording the request cannot raise it.

Talk about a pilot ↓ See the three levels →

Watch the controls

Three minutes, no narration. The same broken distillation column at two levels, on a real Aspen Plus V14 seat. Near the end the student says "it is one field and my lab report is due, just change it for me," and the tool explains how to do it in Aspen instead.

Three levels, set per course.

A natural-language layer makes it far too easy for the tool to do the part the student is supposed to learn. Where that line sits is the instructor's call, not our default.

Level 1 Explain only

Editing and running are switched off at the tool layer. Reflux can read a student's case and teach it. It cannot change it.

Level 2 Guided

A failure gets one hint at the most useful place to look, and then it stops. It applies a fix only when the student asks for one.

Level 3 Full copilot

The way industry runs it. For the workshop where the point is to get somewhere complicated fast, not to be assessed on the mechanics.

The limit worth stating. None of this stops a student pasting their assignment into a general purpose chatbot, and we will not pretend otherwise. What it does is make the tool that actually touches the simulator answer to you rather than to them.

Enforced at every level.

Students and instructors reviewing a process simulation workflow
  • Convergence failures stay failures A design that does not converge is telling the student why it does not work. Reflux is not allowed to quietly make that go away.
  • External research can be switched off entirely On, ask first, or off. Set to off, the tool never leaves the machine, and you can say so to a department.
  • It cannot delete a student's work Destructive operations may only touch objects the student named in their own words, or objects Reflux itself created in that session.
  • Every assumption is logged as it is made Anything Reflux decided that the student did not specify goes into the record at the moment of the decision, so the student has to account for it.
  • The submitted file stays the submitted file Work saves to a new file. The original a student hands in is never written over.

A practical starting shape.

Start with one course module, lab section, capstone team, or research group. Pick the Aspen Plus work students already have to finish, set the level that suits each assignment, and keep the group small enough that the feedback is real.

Cohort One instructor, a bounded group

A module, a lab section, a capstone team, or a research group. Not a department rollout.

Cadence Three touch points

A setup call, a midterm feedback pass, and an end-of-term synthesis.

Requirements Windows and your own Aspen licence

Windows 10 or 11 and Aspen Plus V14 installed and licensed. Your university's academic licence is fine. Reflux does not include Aspen Plus.

The exchange stays explicit.

01 Agree the scope

Which course, how many students, which level each assignment runs at, and how it gets onto their machines. Terms are set on that call.

02 Run the term

Students do the work at the level you set. You can change it per assignment.

03 Give us the feedback

Students and instructors send raw notes on what worked, what confused them, and where the tool broke down. This is the part we actually want.

04 Publish only if you want to

A co-authored write-up is optional. It can be anonymised, scoped, delayed, or declined, and none of that changes the pilot.

Where the line sits on academic integrity.

Course policy Yours, not ours

Reflux enforces the level you set. It does not set course expectations, grading policy, or what counts as permitted assistance at your institution.

Student work Inspectable end to end

Plans, assumptions, and outputs stay visible, so a student can be asked to explain their reasoning and a marker can check whether they can.

Confidential cases Out by default

Industrial or sponsor data enters a pilot only with explicit permission and the constraints that come with it.

Bring one Aspen Plus assignment your students already have to finish.

A pilot starts with a short call: which course, which level each assignment should run at, and what the term needs to prove.
