I'm trying to familiarize myself with FEFLOW, and attempting to model a refined area using an existing regional model. Is there a way to export data (z-coordinates, K-data, head output) from a limited area as defined by a polygon? Or alternatively, having exported that data for the whole model, is there a way to import only the data within the polygon I have defined? Thanks!

i've found out that once the screen is in zoom on part of the model than only the point/polygons which show on the screen are exported.
it may be a bug in the FEFLOW code  ::), but it can be useful for you.
so, you should focus on the area (rectangle) you want to study and then do the export procedure.

I know that exporting only the visible part of the screen looks like a bug, but it has been intended as functionality...

Excellent! A great help, and thank-you. I learned also that ArcView can read the data and export data within a specified polygon. 

In the end, my application was to import the data on to a supermesh that was smaller than the original domain, and any data outside of the supermesh appears to have dissapeared.
