Hello,

As a new user to gid and tochnog I have a couple 
of questions.  

1. ) I am trying to model a corrugated section of 
a grain storage bin and I need to apply a 
hydrostatic pressure load which varies like a 
fluid from the top of the bin to the bottom.  How 
do apply a hydrostatic pressure load to a model 
in gig-tochnog?  When I try to apply conditions 
over surface in gid-tochnog the pull down menu is 
blank.

2. )  Would it be easier to define the pressure 
load in the tochnog input file?  If so how can I 
do this?  The model will be quite large 100k 
elements or so, so doing a pressure load on each 
element by hand wont be practical.

3.)  When working with a 3d shell type element 
where do I define the element thickness and where 
are stresses computed at, top, middle, bottom 
surface?

4.) Is it possible to mix element types together 
in an model, such as solids, plates, shells, 
beams, mass elements?

Thank you,

Brian Reynolds
