Hi guys, I have a problem with my UMAT. The problem is that the variables in it are not declared and there is not the include to 'ABA_PARAM.INC' so there is no specification on the type (single or double precision) of the variables. Then, from the UMAT, there are other calls to subroutines...

Thanks for your help. I think we are almost there but I saw that the "tail" command works only on UNIX, and I am working on Windows. Should I use a converter like unix2dos or something like that?

I tried with your code (wich is very similar to the one used in Marc "run_marc -j myJOB -u mySUB -b no") but it didn't work for me. I uploaded a video in which I show this to you. First I ran an analisys with Abaqus and as you can see although the dimendion of the pippo.odb file increase...

There are 300 increments in the analisys, maybe Abaqus just works differently from Marc. Thank you for your precious advices anyway. ;)

Thanks. I finally make it works launching the analisys form the Abaqus command line and moving everything in the temp directory. Don't ask me why but it works now. Just another question. When I run an analisys with Msc.Marc from command line (same as for batch file you know better than me :D) I...

Maybe you can use a usersubroutine like FORCEDT.

Thanks for the reply. Actually I included the subroutine in the definition of the job, so I run the analisys from the Abaqus window and not from batch. This because I tried with the two batch file as I do with Msc.Marc but it didn't work. If you please explain how to make the two batch file...

In addiction, typing "abaqus info=system":

Hello guys, I am new on Abaqus. I have to perform an analisys with DISP subroutine. The problem I tried and tried but I am not able to make it works. I found several guides and I followed them but it still doesn't work. The problem is about the link between Abaqus and Fortran I guess, because...

Hi! I have a problem with a simulation of the Hopkinson bar experiment. I am using Ls-Dyna with shel axisymmetric elements (tipe 15). In the simulation there is a waves that propagates into the incident bar. It's a pressure wave along y-axis. This wave keeps the bar into the linear-elastic...
