Hallo!!!

Im totally new with Abaqus and I will really appreciate a bit of help...I am more or less able to work with the CAE or with easy input files...The problem came when I realised that I had to work with subroutines...Reading in some foros I saw that I needed the Visual studio and Fortran compiler..I think I download the right versions for my windorws version (windows 7)...I am still downloading the Fortran compiler...But, can somebody tell me how I can check if it works correctly??? I was thinking about running some examples that you can find in the abaqus manual..but can you tell me what exactly should I do???

by the way...I saw some usual soubrutines suich as Dload, Umat....can you tell me if these softwares already have them or if I should do something???

as you can see...im quite lost...thanks a lot for your help!!!

You should use the Fortran version that works with your Abaqus version. Generally its easier to install Fortran before Abaqus as it would setup the necessary variables. You can verify the installation using abaqus verify as mentioned in Abaqus installation and licensing guide. Information about subroutines input / output is available in Abaqus user subroutine reference manual and you would have to write your own subroutine. Hope this hleps you.

ok, here is a sample verification problem
http://www.user.uni-hannover.de:2081/v6.11/books/ver/default.htm?startat=ch04s01abv288.html#ver-sub-umatuhyper

open the Abaqus Command window (start -> abaqus -> abaqus command), then type
abaqus fetch job=umatmst3* (dont forget the *)
this will fetch the inp and the f file into your temp folder (or work folder - the folder you are currently in)
then type
abaqus job=umatmst3 user=umatmst3.f

if there is everything ok with the fortran compiler, this job should compile and execute. then open the odb in the viewer to confirm.


you can also run
abaqus verify -user_exp
to test the same thing basically.
