rmt_create_gcg: Create an 'RMT3DMS' gcg object

In rogiersbart/RMT3DMS: Pre- and post-processing of MT3DMS & MT3D-USGS files

Description

rmt_create_gcg creates an RMT3DMS dsp object.

Usage

rmt_create_gcg(
  mxiter = 1,
  iter1 = 50,
  isolve = 3,
  ncrs = 0,
  accl = 1,
  cclose = 1e-06,
  iprgcg = 0
)

Arguments

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).

Details

mxiter should be higher than 1 when nonlinear sorption isotherm is included or when drycell = TRUE is used in btn.

Value

an object of class gcg
