Hello, thank you for your response. I have updated ANSYS Electronics Desktop to version 2023 R2, and the previous issue has been resolved. However, I have encountered a new challenge. In the new version, I create an arc path with an angle of 359 degrees in the middle of airgap to calculate the air-gap magnetic field. However, when I try to generate the mesh, the mesh generator is unable to create a mesh, and the software hangs. Conversely, if I delete the arc path, the mesh generator works as expected. I have assigned mesh operations with a length-based setting of 1mm=g for both the outer rotor and the arc path edges. However, the problem persists. Could you please help me resolve this issue?
