how the error "current leak to the air" in the Ansys Maxwell can be removed? although there is no error in the validation process

Click For Summary
Discussion Overview
The discussion revolves around the error message "current leak to the air" encountered in Ansys Maxwell simulations. Participants are exploring potential causes and solutions for this issue, which appears during the simulation process despite successful validation. The conversation includes technical troubleshooting and user experiences related to mesh settings and conduction paths.
Discussion Character
- Technical explanation
- Debate/contested
- Exploratory
Main Points Raised
- One participant inquires about the possibility of an electric field gradient exceeding the dielectric strength of air as a cause for the error.
- Several participants report experiencing the same error and seek solutions, indicating a shared challenge.
- One participant claims to have resolved the issue by changing the mesh method to "classic" and increasing the resolution to avoid meshing errors.
- Another participant suggests that the error may arise from an incomplete conduction path in the coil, recommending a check of the coil object for any cracks or open circuits.
- Further advice is given regarding ensuring that long conductors have a full cross-section to the region on both sides to prevent the error.
- A new user expresses confusion about the software's behavior, noting that it continues to run simulations despite errors and questions the normality of long simulation times on their hardware.
Areas of Agreement / Disagreement
Participants generally agree that the error can be related to mesh settings and conduction paths, but there is no consensus on a single solution, as different users report varying experiences and resolutions.
Contextual Notes
Some participants mention specific conditions under which the error occurs, such as the configuration of coils and mesh settings, but these conditions are not universally applicable to all users facing the error.
Who May Find This Useful
Users of Ansys Maxwell, particularly those dealing with electromagnetic simulations and troubleshooting error messages related to current leakage.

Welcome to the PF. 
Can you post a screenshot of your simulation showing the error? You can use the UPLOAD button in the lower right of the Edit window to add an attachment (PDF or JPEG) to your post. Thank you.

Has your model developed a E field gradient that exceeds the dielectric strength of air?

the simulation does not appear and the error is appeared in the message center. can you share the mail so that i can send the screen shot...i am unable to upload the images here.

Hey, update: I solved my problem by changing the Mesh method to "classic" and increasing the resolution enough so that there would be no meshing errors.MohammadKafi said:

Hi guys . if this problem solved by changing mesh it is ok. but sometime it is because of conduction path. if the coil does not have a closed circuit path or it has a crack on the path, this error occurs. so first click on the coil object and check the conduction path . if the problem solved it is good if not or more help was needed reply this message. I don't know if sharing email is a allowed thing or not. I don't mind but I think admins will restrict it.

moreover if you have long conductor that gets in and out to the region, it MUST has a full cross section to the region on both sideszand10000 said:

Thank you so much for your reply and also good information.
I chose the cross section of conductor same to region, but still it had problem . With changing the initial mesh setting to classic, now it has no problem.

Sorry, guys,
I am new to the Ansys electronics desktop and want to simulate the wireless power transferring between two coils. I am simulating some models to learn the software. I am some questions about my simulation and software. I would really appreciate it if you could answer my question.
1. The software continues the simulation even if it has an error!. Should I stop it when any errors occur? For example, as you can see in the attached image, my ongoing simulation has two errors, but the ANSYS continues running!
2. My simulation takes a too long time. For example, with two coils in a 700*700*150 region, it takes more than 10 hours to finish! My Laptop is hp Core(TM) i5-6200U CPU @ 2.30GHz 2.40 with 8GB RAM.
Is it normal for ANSYS?
