EMA3D Current Source Problem

[profiterol 1]

Hello, I want to do an ESD simulation. I used a current source, and the peak value of the signal I used in this source is around 375A. I'm using a current probe to monitor the current flowing from the current source, and when I take measurements from the probe, the peak level of the current is around 575A, which is an undesired situation. (I assigned the current source to the line first, then divided the line into two and assigned the part in contact with the object as PEC. In other words, there is a connection from the domain to the current source, and the current source is connected to the PEC, and the PEC is in contact with the object. I'm taking measurements via PEC.)


I also connected the object to the lower domain with PEC. The meshes can be seen in the attached image. The mesh of the source looks strange; I originally used a straight line, but in the mesh view, it appears as angular lines. Could this be causing the issue? I believe that to conduct a proper simulation, I should see the same current applied to the source reflected in the current probe. Can you help me with this?
