Inverse of the factored system matrix for the DC resistivity problem.
The solution to the DC resistivity problem is necessary at the initial time for galvanic sources whose currents are non-zero at the initial time. This property is used to compute and store the inverse of the factored linear system matrix for the DC resistivity problem given by:
\[\mathbf{A_{dc}} \, \boldsymbol{\phi_0} = \mathbf{q_{dc}}\]where \(\mathbf{A_{dc}}\) is the system matrix, \(\boldsymbol{\phi_0}\) represents the discrete solution for the electric potential and \(\mathbf{q_{dc}}\) is the discrete right-hand side. Electric fields are computed by applying a discrete gradient operator to the discrete electric potential solution.
