Defects extending along the z-direction in BEM of static electric filed simulation

Please login with a confirmed email address before reporting spam

I'm trying to use BEM to calculate the Spatial electric potential field distribution of specific electrodes design, and applied that to trap some charged particles. However, I found that there seems to be some defects of the field that results in extension of the particle arrays in z-direction, which is not physical. And these defects will appear at specific sites, so I suppose it's caused by the defects of field calculation by Comsol. I used user-specified grid, and the grid looks regular, and I calculated the spatial potential distribution, found that there is a 0.001V error for symmetric positions. Are there any solutions to this problem? Thank you!
