EES Professional + Codex on Windows
EES for Codex gives Codex a repeatable way to find EES routines, write a transparent equation model, run your local copy of EES Professional, and check the exported result.
Requires Windows, the ChatGPT desktop app with Codex, and a separately licensed EES Professional installation.
Use the $ees skill to calculate the rate of heat transfer required to increase the temperature of water flowing at 1 kg/s and 200 kPa from 20 C to 60 C.

What the skill contributes
Codex can start an application without a skill. The value here is the engineering workflow applied before, during, and after the solve.
Installation
The plugin supplies the workflow and matching launcher installer. EES Professional remains a separate product installed on your computer.
In Codex, open Plugins from the sidebar. Select Add, then Add Marketplace, and enter the repository below.
Open the plugin and use the available action. Depending on the app version, it may appear as a plus button, Try now, or Install.
Close the matching interactive EES application, begin a new task, and ask the skill to install the launcher for your EES executable.
Use the example prompt below. Codex will preserve the equation file, exported result, and an explanation of the engineering checks.

Use the $ees skill to install the launcher for my EES Professional at C:\EES32\ees.exe. Use the recommended launcher and workspace locations, run the complete installation test with normal Windows filesystem access, and report the exact workspace path.
Use the $ees skill to calculate the rate of heat transfer required to increase the temperature of water flowing at 1 kg/s and 200 kPa from 20 C to 60 C. Save the model and exported result, check units and the energy balance, and explain the assumptions.
YouTube tutorial
The tutorial discusses EES for Codex, shows how to install it and run a simple calculation.
Visit the EES YouTube channelBefore you begin
Windows 10 or 11, Codex in the ChatGPT desktop app, and an existing EES Professional installation.
ees.exe uses the 32-bit launcher and ees64.exe uses the 64-bit launcher. Windows bitness does not make that choice.
The launcher does not require administrator privileges, Python, Node.js, a service, or a system PATH change.
Equation models and exported results are kept in the selected local workspace so the calculation can be reviewed and repeated.
No. EES Professional and its license are required separately. The plugin supplies workflow instructions and the local launcher package.
Codex can open an application directly. The skill adds a consistent model/output contract, catalog-first discovery, controlled execution, stale-result protection, and engineering checks.
No. The workflow helps make calculations transparent and reviewable, but it does not provide professional engineering certification or replace qualified engineering judgment.
