Option name           | Type   | Default Value | Description
----------------------|------- |---------------|------------
"discretization_method" | string | "None"        | Spatial discretization method. "PWLC", "PWLD_MIP".
"max_iters"             | int    | 500           | Maximum iterations for solver convergence.
"residual_tolerance"    | float  | 1.0e-8        | Residual convergence tolerance.
"property_map_D"        | int    | 0             | Material property index to use for diffusion coefficient
"property_map_q"        | int    | 1             | Material property index to use for source.
