Dear all,

I am now set up a model by GW vista Version 4. when I want to assign wall by
polyline method, it comes out: You may not digitize HFB (slurry wall) locations.
How can I sort out this problem?

The other one is I can run my model in MODFLOW 96 package, but I can not run
it in MODFLOW 2000. I found that when I create the datasets for MODFLOW 2000,
there are not datasets created. I know DIS file is require by MODFLOW 2000. I
try to re install the software, but it does not work.

Anyone can give me some tips? Thanks very much

Peter
