                   Equations
                  Set the solver parameters as follows:
                   • Select Pressure in equation tree

                       – Set Convergence Tolerance to 1.0e-6.
                       – Set the Solver field as AMG R-cycle, adaptive.

                       – Set Max Solver Iterations as 1450.
                       – Set Relative Solver Tolerance to 1.0e-2.
                   • To set the parameters of the remaining equations, select Other Variables in the equation tree
                     and use the following values

                       – Set Convergence tolerance to 1.0e-6.
                       – Set the Solver field as GMRES, the Preconditioner field as Block Jacobi and the
                          Subpreconditioner field as ILU.
                       – Set Max Solver Iterations as 100.
