Steps to Export High-Quality Images
Setting Up Your Model View
- Adjust the Model Angle or Dimension: Ensure your model is positioned at the desired angle or dimension.
- Fit Model to Window: Use the fitting button to adjust the model to the default size or your preferred view.

Taking an Image Snapshot
- Accessing Image Snapshot: Click on the 'Image Snapshot' option in COMSOL.
- Adjusting Image Dimensions and Resolution:
- Set the aspect ratio of the image.
- Increase the DPI (Dots Per Inch) for higher resolution. The tutorial suggests using a DPI of 300 or higher.
- Define pixel dimensions, such as 1920x1080.
Exporting the Image
- Clipboard or File Option: Choose whether to copy the image to the clipboard or save it as a file.
- Image Quality Check: Before exporting, check the image's resolution. The tutorial demonstrates an image with a resolution of 3553x2000 pixels.
- Maximum Dimension Limit: Ensure the image dimension does not exceed 4096 pixels on any side.
- Saving the Image: Paste the image into a program like Paint and then save it in the desired format (JPEG, PNG, etc.).
Additional Tips for Image Export
- Title and Axis Inclusion: Decide whether to include the title and axes in the image.
- Exporting 1D Plots: For 1D plots, the tutorial suggests exporting in EPS format for better quality.
- Avoiding the Print Option: The instructor prefers the Image Snapshot over the Print option for better control over image quality.
Conclusion
This tutorial is an invaluable resource for COMSOL Multiphysics users needing to present their simulation results in a visually appealing and high-resolution format. By following these steps, users can ensure their images maintain quality and clarity, even when printed on large canvases or displayed in high-resolution formats.
In summary, exporting high-resolution images from COMSOL Multiphysics is a straightforward process that significantly enhances the visual impact of simulation results. This capability is particularly useful for those presenting their findings in academic or professional settings.
