The LMG package is one of four solver packages for MODFLOW supported by GMS.
This value is the maximum iterations, or calls to the solver. For linear problems, this value can be 2. For non linear problems, this values should be larger, but generally less than 50.
This value is the maximum number of iterations per call to the solver. The default value is 50, and this is sufficient for most problems.
Three different acceleration methods are available: constant, adaptive damping using the Cooley method, or adaptive damping using the relative reduced residual. Refer to the official package documentation for more explanation on the different damping methods.
This value is used if the acceleration method is set to constant. Usually, this value is 1.0, but for some problems lower values may help achieve convergence.
This is the max damping value when using the adaptive damping with relative reduced residual.
This is the min damping value when using the adaptive damping with relative reduced residual.
When the scaled norm of the matrix equations is less than this value then the solver iteration stops.
Controls whether the conjugate gradient method is used to accelerate the solver. By default this option is on.
These variables are used to control the amount of memory storage used by the solver. The defaults rarely need to be changed.
This button will change all options to the default state.
