THE LUMBER KILN SIMULATOR
​​​​​
-
An educational tool for industry and academia to study the effect of kiln type, wood species, lumber properties, temperature schedule, air speed, sticker thickness, fan reversals, etc. on final moisture content distribution, internal stresses and productivity
-
Educators with a yearly subscription can get a 1 month free subscription for each student. Contact us about this offer or when it is time to give the students access.
Get a 7-day free trial. Check your downloads folder for the file.

-
Conditioning step added.
-
Bug fixes: choice of entering/average/exiting air temperature control; missing key prompt
-
Known issues: Slow simulations due to a recent update. It will soon be solved
​
On the first run in Windows it might take a minute to pass security checks
​
When the trial runs out, you will be prompted for a key. Then, get a MONTHLY or YEARLY subscription and enter the key that you will get in the email.

System Requirements for the Lumber Kiln Simulator
Our simulator is a modern, cross-platform application. To ensure a smooth experience, please review the following system requirements for your operating system.
​
Key Requirement for All Systems
The most important component for the simulator's 3D kiln preview is a graphics card that supports OpenGL 3.3 or higher. Most computers manufactured from 2015 meet this requirement.
​
For Microsoft Windows
Minimum Requirements:
(Sufficient for running small to medium-sized simulations with a responsive interface.)
-
Operating System: Windows 10 (64-bit)
-
Processor (CPU): Dual-core processor, 2.0 GHz or higher (e.g., Intel Core i3 / AMD Ryzen 3, 4th generation or newer)
-
Memory (RAM): 8 GB
-
Graphics Card (GPU): Integrated graphics (Intel HD/UHD Graphics) or a dedicated card with support for OpenGL 3.3.
-
Storage: 500 MB of free disk space for installation.
-
Screen Resolution: 1280x720
​​
Recommended Requirements:
(For a smooth experience with large, multi-zone simulations and a fluid 3D preview.)
-
Operating System: Windows 11 (64-bit)
-
Processor (CPU): Quad-core processor, 2.5 GHz or higher (e.g., Intel Core i5 / AMD Ryzen 5, 8th generation or newer)
-
Memory (RAM): 16 GB or more
-
Graphics Card (GPU): Dedicated NVIDIA or AMD graphics card with at least 2 GB of VRAM (e.g., NVIDIA GeForce GTX 1650 / RTX series, AMD Radeon RX 500 series or newer).
-
Storage: 500 MB of free space.
-
Screen Resolution: 1920x1080 (Full HD)
​
For Linux
Minimum Requirements:
(Sufficient for running small to medium-sized simulations with a responsive interface.)
-
Operating System: A modern 64-bit Debian Linux distribution (e.g., Ubuntu 20.04 LTS, Linux Mint 21, or newer).
-
Processor (CPU): Dual-core processor, 2.0 GHz or higher (e.g., Intel Core i3 / AMD Ryzen 3, 4th generation or newer)
-
Memory (RAM): 8 GB
-
Graphics Card (GPU): Graphics card with OpenGL 3.3 support and properly configured drivers.
-
Storage: 500 MB of free disk space for installation.
-
Screen Resolution: 1280x720
​
Recommended Requirements:
(For a smooth experience with large, multi-zone simulations and a fluid 3D preview.)
-
Operating System: A modern 64-bit Debian Linux distribution with the latest updates (e.g., Ubuntu 22.04 LTS or newer).
-
Processor (CPU): Quad-core processor, 2.5 GHz or higher (e.g., Intel Core i5 / AMD Ryzen 5, 8th generation or newer)
-
Memory (RAM): 16 GB or more
-
Graphics Card (GPU): A dedicated NVIDIA or AMD graphics card with the proprietary drivers installed. (e.g., NVIDIA GeForce GTX 1650 / RTX series, AMD Radeon RX 500 / 6000 series or newer).
-
Storage: 500 MB of free space on a Solid State Drive (SSD).
-
Screen Resolution: 1920x1080 (Full HD)
​
Important Note for Linux Users:
The 3D visualization features of the simulator rely heavily on good graphics acceleration. For users with dedicated NVIDIA or AMD graphics cards, it is highly recommended to install the official proprietary drivers provided by the manufacturer. The default open-source drivers (e.g., Nouveau for NVIDIA) may result in poor performance or visual artifacts in the 3D kiln preview.
