superelement mesh

Hi, I'm a fist time Feflow user and I need some help that I could not find in the software help. I want to know which variables do I have to use to create a superelement mesh and a finite element mesh. Since I have, area, rivers, topography, observation wells.

I also want to know why I cannot acivate 3D in the dimension menu.

I would recommend that you go through the demonstration exercise described in the booklet of the FEFLOW DVD. I think this will answer most of your questions.

Thanks for your answer Peter,
but when I got to the II.3.2. section of the exercise (the 3rd dimension) I could not enable the Three-dimensional (3D) option. Do you think the problem is the resolution of my monitor (1280X800), or can it be anything else? Even my monitor does not have the proper resolution, the program is running normally. I can even load the 3D_demo files and when I do that the 3D option is enabled.

OK, in fact the problem was the monitor resolution. Thanks again!
