Problem with Ansys Maxwell "current leak to the air"

In summary, the issue of "current leak to the air" in Ansys Maxwell refers to unintended current paths that can occur in electromagnetic simulations, potentially leading to inaccurate results. This problem typically arises from improper boundary conditions or model configurations, resulting in currents escaping the intended conductive regions. Users are advised to carefully review their simulation setup and ensure that boundaries are correctly defined to mitigate this leakage and improve the accuracy of their analyses.

Hi everyone, I am currently trying to simulate an electric plasma arc (tip to tip configuration), same as the one shown in the picture here, I made the vacuum region such as it is 50% from the sides, and touches the current in and out region
However when I run the analysis, I am getting the following error "current leak to the air"
Anyone can help me figure out what the issue might be and how to fix it? I tried a more refined mesh too, same issue
any tip is appreciated I am still new to maxwell

FAQ: Problem with Ansys Maxwell "current leak to the air"

What causes current leakage to the air in Ansys Maxwell simulations?

Current leakage to the air in Ansys Maxwell simulations can be caused by several factors, including improper boundary conditions, inadequate mesh refinement near the edges, or insufficient insulation in the model setup. Additionally, the presence of air gaps or high electric fields near conductive materials can lead to unintended current paths.

How can I prevent current leakage in my Ansys Maxwell model?

To prevent current leakage, ensure that the boundary conditions are correctly set, particularly at the edges of the model. Use a finer mesh in areas where high gradients are expected, and consider adding insulating materials or increasing the thickness of existing insulation. Also, review the geometry for any unintended air gaps that might allow leakage.

Is there a way to visualize current leakage in Ansys Maxwell?

Yes, you can visualize current leakage by using the post-processing tools in Ansys Maxwell. You can plot electric field lines, current density, and potential distribution to identify areas where leakage may occur. The results can help you understand the flow of current and pinpoint regions that require attention.

What are the implications of current leakage in my simulation results?

Current leakage can significantly affect the accuracy of your simulation results. It may lead to incorrect predictions of electric fields, reduced efficiency, and potential overheating in real-world applications. Therefore, it's crucial to address any leakage issues to ensure that your model reflects the true behavior of the system.

How can I troubleshoot current leakage issues in Ansys Maxwell?

Troubleshooting current leakage involves a systematic approach. Start by reviewing your boundary conditions and geometry for any errors. Next, refine the mesh in critical areas and check the material properties for accuracy. You can also run sensitivity analyses to identify the impact of various parameters on leakage. If problems persist, consulting the Ansys documentation or forums for similar issues may provide additional insights.
