Femtet Help/Manual

Electric wall is set as follows.

Select Electric wall on Electric tab in the [Edit Boundary Condition] dialog box.

The electric field is set to be normal to the boundary. The type of electric wall can be selected in the combo box.

Setting Item	Notes
Current Specified	Inflow Face Specified current flows into the analysis domain from the face of electric wall. The electric potential on the face of electric wall is uniform. Outflow Face (Ground) Used for the current which is flowing out of the analysis domain. The electric potential on the face of electric wall is treated as 0V.
Electric Potential Specified	Specifies the electric potential on the face of electric wall.
Floating Electrode	Defines the electrode whose electric potential is unknown. In other words, the floating electrode is the unknown equipotential boundary. The nodes on this boundary will have the same "unknown" number and the same voltage. When the calculation is completed, the electric potential of the floating electrode will be acquired.
