Why?¶

This is actually sick.

The “dragging windows around to see values” line is painfully real. Aspen/HYSYS has this special ability to make you feel like half the work is engineering and half the work is negotiating with the UI.

How?¶

aspen-pysys enables users to programmatically obtain and update values on the Aspen HYSYS app through a highly abstracted Python layer. For that to happen, this API employs statically typed code to help your IDE look out for type misalignment and prevent runtime errors. There are consequently several types to represent different HYSYS data, ranging from simulation cases to heat exchangers.
