Charge Density Condition¶
The charge density condition specifies the distribution of charge density \(\rho\) in a volume, on a surface or along a line (wire) depending on the provided marker:
\[
\left. \rho \right|_{\Omega} = \rho_0(x,y,z),
\]
where \(\Omega\) is the given region of space (volume, surface, or line) and \(\rho_0(x,y,z)\) is the desired charge density.
