Bases: MFPackage

ModflowGwtgwt defines a GWTGWT package.

Parameters:

  • gwfmodelname1 (string) – keyword to specify name of first corresponding gwf model. in the simulation name file, the gwt6-gwt6 entry contains names for gwt models (exgmnamea and exgmnameb). the gwt model with the name exgmnamea must correspond to the gwf model with the name gwfmodelname1.

  • gwfmodelname2 (string) – keyword to specify name of second corresponding gwf model. in the simulation name file, the gwt6-gwt6 entry contains names for gwt models (exgmnamea and exgmnameb). the gwt model with the name exgmnameb must correspond to the gwf model with the name gwfmodelname2.

  • auxiliary ([string]) – an array of auxiliary variable names. there is no limit on the number of auxiliary variables that can be provided. most auxiliary variables will not be used by the gwt-gwt exchange, but they will be available for use by other parts of the program. if an auxiliary variable with the name ‘angldegx’ is found, then this information will be used as the angle (provided in degrees) between the connection face normal and the x axis, where a value of zero indicates that a normal vector points directly along the positive x axis. the connection face normal is a normal vector on the cell face shared between the cell in model 1 and the cell in model 2 pointing away from the model 1 cell. additional information on ‘angldegx’ is provided in the description of the disu package. angldegx must be specified if dispersion is simulated in the connected gwt models.

  • boundnames (keyword) – keyword to indicate that boundary names may be provided with the list of gwt exchange cells.

  • print_input (keyword) – keyword to indicate that the list of exchange entries will be echoed to the listing file immediately after it is read.

  • print_flows (keyword) – keyword to indicate that the list of exchange flow rates will be printed to the listing file for every stress period in which ‘save budget’ is specified in output control.

  • save_flows (keyword) – keyword to indicate that cell-by-cell flow terms will be written to the budget file for each model provided that the output control for the models are set up with the ‘budget save file’ option.

  • adv_scheme (string) – scheme used to solve the advection term. can be upstream, central, or tvd. if not specified, upstream weighting is the default weighting scheme.

  • dsp_xt3d_off (keyword) – deactivate the xt3d method for the dispersive flux and use the faster and less accurate approximation for this exchange.

  • dsp_xt3d_rhs (keyword) – add xt3d dispersion terms to right-hand side, when possible, for this exchange.

  • perioddata (record mvt6 filein mvt6_filename) – Contains data for the mvt package. Data can be passed as a dictionary to the mvt package with variable names as keys and package data as values. Data for the perioddata variable is also acceptable. See mvt package documentation for more information.

  • observations (record obs6 filein obs6_filename) – Contains data for the obs package. Data can be passed as a dictionary to the obs package with variable names as keys and package data as values. Data for the observations variable is also acceptable. See obs package documentation for more information.

  • dev_interfacemodel_on (keyword) – activates the interface model mechanism for calculating the coefficients at (and possibly near) the exchange. this keyword should only be used for development purposes.

  • nexg (integer) – keyword and integer value specifying the number of gwt-gwt exchanges.

  • exchangedata ([list]) –
