Computer Aided Thermodynamic Tables 3 Download Better Free Jun 2026

An open-source alternative that is excellent for those who know a bit of Python, MATLAB, or Excel.

It generates graphical representations like T-s (Temperature-entropy) and P-v (Pressure-volume) diagrams, which can help visualize processes like isentropic expansion.

Computer Aided Thermodynamic Tables 3 (CATT3) is a highly sought-after software tool for engineering students and professionals working with thermal fluids. It replaces traditional, tedious printed thermodynamic tables with a fast, digital calculator for property values. An open-source alternative that is excellent for those

CATT3 is a specialized software package designed to provide accurate thermodynamic property data for a wide range of substances. Originally developed to accompany major thermodynamics textbooks (like those by Borgnakke and Sonntag), it replaced the back-of-the-book printed tables with a fast, point-and-click interface. Key Features:

Maintained by NIST, these tables cover 47 elements and their compounds, providing key temperature‑dependent thermochemical properties including heat capacity, enthalpy, entropy, Gibbs free energy, and more. Available for free online access.

Provides properties such as pressure, temperature, specific volume, internal energy, enthalpy, and entropy.

Most engineering departments own campus-wide licenses for CATT3 or similar tools. Check your university’s IT services page or student portal to download it legally for free. This link or copies made by others cannot be deleted

A: No, CATT3 is Windows-only. However, alternatives like Thermonator and DWSIM Calculator offer mobile thermodynamic calculations.

I understand you're looking for a free download of by Sonntag, Borgnakke, and Van Wylen.

Cracked or modified versions of CATT3 are often unstable, leading to frequent crashes or, worse, incorrect data calculations that ruin your engineering assignments.
