XPSIM – Version 3.02 mod 02

What is new

This document summarizes new features available in version 3.02 mod 02 of XPSIM (eXtended Process Simulation) officially issued on July, 2026.

This version was developed for x64-based PC running on Windows 11 operating system.

In addition to minor corrections applied to the steady-state and dynamic engines as well as to the Windows interface, the following improvements are available:

A. Steady state simulation

All the modifications and corrections issued for the 3.02 initial version and the following mod.01 version have been incorporated and consolidated.

Unit Operations

The simulation of “shell & tube heat exchanger” (HXSHTB) is now available.

B. Dynamic Simulation

All the modifications and corrections issued for the 3.02 version and the following mod.01 version, and the following modifications, have been incorporated and consolidated.

A dynamic simulation of a COLUMN section is now available in its initial release. One example can be viewed on the YouTube channel XPSIM.

The Dynamic Simulation Option has been used in the following fundamental studies recently published:
