I'm not sure what you mean by importing the grid to MODFLOW because ModelMuse already creates a discretization file which is how the grid is defined in MODFLOW. You mentioned the .vmg file which is a file format used by Visual MODFLOW. It's format is described in the following URL.
ModelMuse does not create .vmg files. However, you could use some of the commands in ModelMuse to extract the required information and then use Excel and a text editor to put it in the right format. There are commands under the Grid menu that allow you to edit the row and column line positions. You could select the cells in the tables there and copy to the clipboard. There is also a command under the Data menu for displaying data set values. It also allows you to copy to the clipboard. In Excel, you can use the Paste Special | Transpose command to put the elevation data in the order used by Visual MODFLOW.
Hi,Can I generate a MODFLOW grid in Model Muse, then export it to something (.VMG, binary file, etc...) that I can import in MODFLOW ?
Thanks
