rmt_create_gcg creates an RMT3DMS dsp object.
rmt_create_gcg( mxiter = 1, iter1 = 50, isolve = 3, ncrs = 0, accl = 1, cclose = 1e-06, iprgcg = 0 )
| mxiter | maximum number of outer iterations. See details. Defaults to 1. |
|---|---|
| iter1 | maximum number of inner iterations. Defaults to 50. |
| isolve | type of preconditioner: 1 = Jacobi, 2 = SSOR, 3 = Modified Incomplete Cholesky (MIC; default). |
| ncrs | integer controlling treatment of dispersion tensor cross-terms. If 0 (default), lump all dispersion cross-terms to RHS. If 1, includes full dispersion tensor. |
| accl | relaxtion factor for the SSOR preconditioner. Defaults to 1. |
| cclose | Convergence criteration in relative concentration. Defaults to 1e-6. |
| iprgcg | interval for printing maximum concentration. changes of each iteration. Defaults to 0 (only print at end of stress-period). |
an object of class gcg
mxiter should be higher than 1 when nonlinear sorption isotherm is included or when drycell = TRUE is used in btn.
