Detailed Description

calculate essential boundary conditions

\[ \mathbf{F} = \int_{\partial\Omega} \ \mathbf{u} \cdot \mathbf{j}_i \textrm{d}{\partial\Omega} \]

where \(\mathbf{j}_i\) is current density function.

Here simple current on coil is hard coded. In future more general implementation is needed.
