Pricing
Start free on one seat. Everything else is a conversation, and it starts with a form, not a sales call.
One seat of Aspen Plus, on your own licence
Then $39 a month, $139 a semester, or $390 a year. Model usage included in each plan.
A course, lab section or capstone team
Terms set on the setup call. One instructor and a bounded group to start.
Teams and private deployment
Quoted for your group. Private cloud or fully on site when the data cannot leave.
Simulation software makers
Nothing to start. Embed, co-sell or refer, and your licence stays the gate.
Prices in US dollars. Reflux does not include Aspen Plus; you need your own licensed seat.
Custom models
A model trained on your process data, deployed where your data lives. The scope document carries the number before any work starts.
Free to start is a trial with a limit on it, not a free product. There is no card to enter. When it runs out the app shows you the plans and you pick one, or you stop.
Yes. Reflux drives Aspen Plus V14 through its published automation interface on Windows 10 or 11. A university's academic licence is fine. Aspen Plus is a product of Aspen Technology, Inc.; Reflux is not affiliated with or endorsed by AspenTech.
Yes. The semester pass is $139 for four months and the annual pass is $390. Both include model usage, and a plan you paid for runs to the end of its period if you cancel.
Per seat, quoted for your group, with private cloud or on-site deployment as part of the same conversation. Get a demo and we will put a number in writing.
Tell us which one on the simulator form. Adapters are built against each package's own automation interface, and the ones with the most demand go first.
Install it beside Aspen Plus and hand it the case you are stuck on. No card, no call.
