Why does the electrical potential not go the way I wanted?

[Zivy98]

Hello guys, I do not understand why the potential does not go along the U shape? It seems that it jumped over the space from one structure to another. This is very confusing, I attached a pic if it helps. Thank you in advance.

Can you provide more details ? What are the boundary conditions ? What materials are used for each region ? How are the regions connected (any tie constraints or electrical contact) ?

Hi, thank you for your reply. The problem is already solved. The problem was that I defined the electrical conductivity of the board. I wish you a nice weekend!

If you don't want the electrical potential to transfer from the circuit to the plate, you can also disable that DOF in tie constraint:

*TIE, NO ELECTRIC POTENTIAL

This way the tie constraint will only provide mechanical (and thermal if applicable) connection.
