Hi Tochnogers,

I'd like to share with you some issues I'm having when using tochnog.
I'll do appreciate any help on this matter:

1)	Some time ago I started learning how to use Tochnog, and it
seems to suit to my needs for my PhD research. But with my last model I
have a problem: It's 14507 nodes and 77255 -tet4 elements. I'm
performing a elastic calculation. The problem is that it last about 3
minutes to calculate the problem and it writes the database (.dbs file),
but it doesn't print the GiD files (even after one hour running!!). I've
tried with smaller models and GiD printing works fine. I really don't
know what is going on, and how can I overcome that. I have tried running
it in Windows, Linux (within a virtual machine), but nothing. I
recompiled it (linux_old) and nothing. Probably it's due to the size of
the problem, but if it writes the whole .dbs file, which is circa 50 MB
large, why doesn't it print the GiD files, which should be smaller?

2)	I'd like to know if there's a flux diagram of the code.

3)	Has somebody compiled tochnog for analyzing just some specific
type of problem? I mean if I will be involved just in modeling of solids
with a linear elasticity constitutive model, is it possible to compile
the code in order to solve that. I ask this because I think that being
compile for an unique propose would make it run faster, wouldn't it?

4)	How can Tochnog be compiled for 64 bits? - in Linux I tried
replacing the flag -m486 by mtune=native, but it doesn't compile. 

Well, I think this is all for now. Thank you very much for your help.

cheers,

Ferney
