06.Set the Boundary Conditions

Set the boundary conditions to the electrodes.

You need to set boundary conditions on some parts of model's body (topology).
It varies depending on the analysis.

The boundary conditions are distinguished by name. It is not allowed to assign the same name to the different boundary conditions
