Next we will set the options for the MODFLOW 6 solver package. Select Model|MODFLOW Packages and Programs and go to the Solvers Pane. On the Nonlinear tab, override the value of Outer HClose and set its value to 10-6. Also override the Outer maximum iterations and Under-relaxation scheme and set them to 100 and None respectively. On the Linear tab, override the values of Inner maximum iterations, Inner HClose, Inner RClose, Linear acceleration, and Relaxation factor. Set their values to 300, 10-6, 0.01, BICGSTAB, and 0.97 respectively. Click OK to close the dialog box when you are done.
