IBFLG problem for Modflow-LGR V2

[Laure_A]

Hi everyone,

It's my first model with Modflow-LGR V2. After the Run, I have an error message saying "IBFLG must be <0 for child grid". Where/How can I change this parameter ?

In the Child Models window, I don't have the option to change the IBFLG.

For the modflow-lgr version, I download the available version mflgr.1-2 :

Water Mission Area Legacy Software (usgs.gov)

Here some screenshots :

1) Opening window before start running

2) IBFLG error after running

3) Options in my Child Models window

 

Thank you for your help.

Laure

You need to make sure that there are active cells in the parent grid on all edges of the child grid.
