Hi Air Conditioning Engineers User,

Its my pleasure to show the the second beta version impression of the HVAC Tool GUI for OpenFOAM®. It is just under development but I hope it will be usefull for the HVAC Engineer of the next generation.

18. August 2012: news:
- Import function IFC Format
- Import and export function for TRNSYS and OpenFOAM®
- Edit/Object-Mode for 3D Objects
- Create your own HVAC libraries
- Used OpenFOAM® Windows 64bit 2.1.x
- Easy CaseSetup for HVAC Simulation
- Easy BlockMesh and SnappyHexMesh Export
- Calculate sun position for boundary (GEOSURF Factor)
- Comfort analysis like DIN EN ISO 7730

You can download a DEMO Version:


Simulate instead of modeling! HVAC Tool...

Hi Andrés,

you can download from the website:

or use a FTP Software:

HVAC Tool Version
Hello OpenFOAM® HVAC users.

We finished the new version and its available now as a demo version on the website

The new extension of our tool includes new solvers like:

other features are included:
- Export the boundary conditions to Excel
- Preliminary estimates with potentialFoam
- Workflow Improvements

The demo version allows you to use every function so you can test the whole HVAC tool in your own individual way. The Demo is for Windows® 64bit System, Vista, 7 and 8. OpenFOAM® for Windows® should be installed on Windows system already.

Check it out and you will feel the new generation of fluid dynamics for building simulation.

This looks really good. If this kind of GUI is made of Openfoam 2.x, it will be really good and very easy to start work.

It is my thoughts...

thank you!

I'll give you a training file attached. It is the Shanghai World Financial Center. The training file is fictional and has nothing else to do with the reality. I hope the exercise will help you.

Simply load the file and export it as OpenFOAM case. Then run the blockMesh and snappyHexMesh. At last step start the solver. That's it.

For the analysis using ParaView.

Important: Change to SWFC.7z. I used 7-zip!

Have fun
