hi.
I'm trying to delete some points from a mesh. There's a mountain in the middle of valley aquifer I'm trying to model. I assume the aquifer has a hole in that area(no porous media, just mezosoic rocks) , that's why I try to delete those points from the mesh and set boundary conditions (recharge). In the user manual for version 6.x this is a really simple operation, but somehow the "delete button" is not active as shown in the pic in this picasa link ( https://picasaweb.google.com/lh/photo/I1twrbMwgkmC0j32wVdcnjcqu0fHZjp4pFwkjBediDo?feat=directlink ). Anyone knows what's going on?
Similar situation to this post (http://www.feflow.info/forum/index.php/topic,306.msg672.html#msg672) , except that delete button is not working.
p.s I used the tutorial data to make sure nothing's wrong.
