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? You can try telling tochnog to print the gid file. I normally ask the = program to print the results for all the=20 calculation steps. In that way you can see how the results are changing = or get results for all the loading conditions try for example control_timestep 10 1.1 6.1 6 500 ...... control_timestep_iterations 10 3 control_print 10 -time_current -post_node_rhside_ratio control_print_database 10 -yes=20 control_print_gid 10 -yes end_data 2) I'd like to know if there's a flux diagram of the code. NO there is not. Check the program manual on the web. 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? No. Tochnog is a multidisciplinary FEA program. 4) How can Tochnog be compiled for 64 bits? - in Linux I tried replacing the flag -m486 by mtune=3Dnative, but it doesn't compile.=20 In linux you need to use -mcpu=3Dcpu-type Tune to cpu-type everything applicable about the generated code, except = for the ABI and the set of available instructions. The choices for = cpu-type are i386, i486, i586, i686, pentium, pentium-mmx, pentiumpro, = pentium2, pentium3, pentium4, k6, k6-2, k6-3,athlon, athlon-tbird, = athlon-4, athlon-xp and athlon-mp. and -m64 For OSX you can check the makefile for darwin-intel Well, I think this is all for now.
