read.DIS: Read a discretisation (DIS) package file

In CJBarry/Rflow: Tools for analysing and writing input and output files for USGS MODFLOW

Description

Reads information from a MODFLOW-2000 DIS package file. The DIS package contains information about the finite difference grid, including layer elevations, and stress period set up. It also tells the layer types.

Usage

read.DIS(file)

Arguments

file	character string; file name

Value

a list of class "DIS.MFpackage" with elements:
$extent: a vector whose named elements are NLAY, NROW, NCOL, NPER, t_unit, l_unit
$LAYCBD: integer vector indicating the equation type used for each layer (confined or unconfined, see MODFLOW-2000 documentation)
$DELR: column spacing (along rows), may be a single constant value
$DELC: row spacing (along columns), may be a single constant value
$elev: a vector of layer divide elevations or a 3D array of distributed layer divide elevations by cell
$sps: a data.frame with stress period descriptions:
..$PERLEN (num): stress period length
..$NSTP (int): number of time steps in the stress period
..$TSMULT (num): time step multiplier
..$TR (log): does the stress period use transient equations?

Examples

fnm <- system.file("rflow_mf_demo.dis", package = "Rflow")

dis <- read.DIS(fnm)
class(dis)
str(dis)
