About VERSE Web

VERSE Web is a thin web frontend for the VERSE chromatography simulator, originally developed at Purdue in the 1990s–2010s. This site runs the 2014 batch engine (ree.exe) as a background service and streams the results back to your browser.

How it works

You paste or upload a VERSE input file. The server queues a job, a single worker process runs ree.exe under Wine on a Linux host, and as soon as the simulation finishes the page updates with the effluent-history chart, axial profiles, and full log. Simulations run one at a time on a modest instance, so long jobs may wait their turn.

Limits on this instance

• Max input size: 256 KB (VERSE inputs are tiny text files).
• Max components × axial_grid: 10,000 (keeps memory safe).
• Max runtime: 1 hour (simulations over this are killed).

Coming soon

Automated parameter estimation — upload experimental effluent data alongside an input template, and the system will fit the isotherm coefficients via a machine-learning-in-the-loop optimizer.
