One of the things that ModelMuse can do is to import a MODFLOW-2005 model.
I'm going to do that now.
I started ModelMuse and I click import MODFLOW-2005 model.
Click Next.
Select the Name file for the model.
In this case, I'm going to select a model that comes with MODFLOW-2005.
Click Open
Click OK.
It reads the input for the model and imports the model.
So now I can visualize things about the model such as the top of the model.
Or I could look at the hydraulic conductivity.
Or I could look at where general head boundaries are.
Or I could look at where streams are located.
All that's pretty nice.
Now, if you were to edit the model, this would be a good starting point but you can run into some problems when  you try to edit it.
For example, suppose I look at these streams and I want to refine the grid.
So I'm going to subdivide all these grid cells into three rows and three columns.
I'm going to take another look before I do this.
There are nice continuous stream channels.
I click OK.
The grid is refined.
We'll hide the grid lines.
And now all the stream channels are discontinuous.
This is not at all realistic.
Now what's going on here?
Well, when ModelMuse imported the streams, it only knew that the streams were located at some particular cells.
So it created objects such as this one...
Let's turn off the streams for a moment; it might make it a little clearer.
So here is an object that defines one stream that is composed of a series of vertices that are separated.
Each one is a separate section of the object.
That was fine before we had subdivided the cells but now it is not so great.
We could try to join them up into a continuous stream like this.
And that will actually work fairly well in this case.
I'm making the streams fairly continuous - not perfectly.
I'll continue to do all these.
So what I'm doing here is each of these vertices is a new section so when I clear that check box, that means it's not a new section any more.  
There is a line segment connecting each vertex 
to the one after it or the one before it depending on your point of view.
OK so let's look at the streams again.
First I'm going to hide all the objects.
And now let's display the segment number.
And that's much better.
You'll notice, however that the segments are not perfectly connected and they don't extend all the way to the edge of the grid.
So if you refine the grid that you have used with an imported model, you can run into some problems.
Thank you.
