This class solves the fully implicit black-oil system by solving the reduced system (after eliminating well variables) as a block-structured matrix (one block for all cell variables) for a fixed number of cell variables np .
◆ ISTLSolver() [1/2]
Construct a system solver.
- Parameters
-
[in] | simulator | The opm-models simulator object |
[in] | parameters | Explicit parameters for solver setup, do not read them from command line parameters. |
[in] | forceSerial | If true, will set up a serial linear solver only, local to the current rank, instead of creating a parallel (MPI distributed) linear solver. |
◆ ISTLSolver() [2/2]
Construct a system solver.
- Parameters
-
[in] | simulator | The opm-models simulator object |
◆ iterations()
Solve the system of linear equations Ax = b, with A being the combined derivative matrix of the residual and b being the residual itself.
- Parameters
-
[in] | residual | residual object containing A and b. |
- Returns
- the solution x
