How to Speed Up Simulations in AN-SOF: Tips for Faster Results

Learn how to optimize simulation speed in AN-SOF Antenna Software. Follow valuable tips for faster results by adjusting segments, resolution, and settings. Turbocharge your antenna simulations!

When it comes to simulations, there is always a trade-off between speed and accuracy. However, in the initial stages of antenna design, prioritizing speed is often crucial. To help you speed up your calculations in AN-SOF, here are some valuable tips:

1. Start with the Minimum Number of Segments

  • Begin with 10 segments per wavelength.
  • AN-SOF allows you to set the minimum recommended number of segments by entering β€œ0” (zero) as the number of segments for any wire.
  • To select a group of wires and massively edit the number of segments per wavelength, follow this guide: Modifying a Group of Wires.
  • For wire grids, use one segment per cell side if the electrical size of each cell is less than 10% of the wavelength.

2. Adjust the Quadrature Tolerance

  • Navigate to the Setup tab > Settings panel and set the Quadrature Tolerance between 5% and 10%.
  • This parameter primarily affects simulations involving parallel wires that are very close to each other (approximately two wire radii apart).

3. Reduce the Interaction Distance

  • Go to the Setup tab > Settings and set the Interaction Distance to 0.1Ξ» (or even zero).
  • This setting is relevant only for parallel wires that are in close proximity to one another.

4. Optimize Spatial Resolution for Gain, Directivity, and Efficiency Calculations

  • For calculating gain, directivity, and efficiency, a spatial resolution of 5 or 10 degrees in the far-field is usually sufficient.
  • Access the Setup tab > Far-Field panel and set Theta Step to 5 degrees and Phi Step to 10 degrees.

5. Calculate Only What You Need

Results

By implementing these strategies, you can significantly enhance simulation speed. For example, the figure provided illustrates a case where the simulation runs more than three times faster, especially when setting the Interaction Distance to zero.

You can find the β€œcar.emm” project in the Examples folder, which is installed along with AN-SOF, or you can download the model by clicking the button below.

Remember: Finding the right balance between speed and accuracy is essential. These tips will help you achieve faster simulations in AN-SOF Antenna Simulation Software.
