How to Use This Tool

  • Choose Method: Select from preset microstructures, upload your own image, or draw a custom design.
  • Set Parameters: Adjust the thermal conductivity ratio (κ₁) and direction angle (α) to see how they affect heat transfer.
  • Analyze Results: View heat flux and temperature distribution across your microstructure.
  • Interact: Zoom, pan, and download any visualization for further analysis.
