Title

Incremental Driver

Description

Incremental Driver is a single element code developed by Andrzej Niemunis (2007, 2014) for running element tests using constitutive models implemented in umat format. Virtually any element test may be simulated using a general test specification procedure described in the software manual, standard tests are pre-defined.

    I have tried to compile IncrementalDriver to use it with sanisand model. I found it impossible to compile due to absence of the module unsymmetric_module called in the first line of the main program. The module unsymmetric_module is also called in the subroutines get_increment and rotsig. Can anyone help?
    Regards,
    Krzysztof

      Hi Krysztof, I do not know myself, but will try to forward your question to Andrzej Niemunis, Incremental Driver author. Maybe also someone else helps. In the meanwhile, you can run sanisand umat in soilmodels.com/triax, but you would need Linux to link umat. Regards David

    Thank you for the quick reply!
    There is one more problem. When I eliminated the calls of the module unsymmetric_module by putting them into comments (! at the beginning of the line) the compiler revealed that some other subroutines are missing, i.e. map2T, map2stress, map2d, map2stran. Probably these subroutines were included in the same file IncremetalDriver.f in its previous version, but in the updated version of IncrementalDriver they have been moved to external file(s).
    I will try to compile sanisand umat in triax under Linux anyway. Thank you for the hint. Regards, Krzysztof

    Dear Krysztof, if you like I can also give you some hints how to compile it under windows, with the same commands.

      Hi Henning, it would be great if you could provide the explanation. I will then put that info directly into the download package description.

    Dear Henning, I warmly welcome your help. The problem is that triax is coded in C++ which I do not use. I use Fortran, that is why IncrementalDriver was my first choice. Only very recently I installed the free compiler and IDE Dev-C++ under Windows. If this fact does not discourage you, I am open to any help.

      Krysztof, I now uploaded updated version of Incremental driver, provided by Andrzej Niemunis in 2016. Please try this, maybe it resolves your problems. If not, Andrzej replied that he will check your problem.

    Hi David and Krysztof,

    I will do in the next days. Basically, you can install cygwin64 and must add it to the path variable in windows. As I remember this should be enough. The problem is that I have done it a long time ago. I have to repeat it on a computer without the installation.

      Hi Hennig, thanks for help. As a matter of fact, the version of Incremental Driver was older, which was probably the cause of the troubles of Krzystof. I have uploaded the most recent version (2016) yesterday and it seems Krzystof could compile it. I think you can let it be for now, maybe do it later if someone else is in trouble. Regards David

    Henning, David is right. I will try using incrementalDriver and see what happens. Anyway, I appreciate your help! Maybe I’ii take advantage of it in the future.

        Krzysztof, still some news. Andrzej Nimeunis just provided 2017 version of Incremental Driver, which can now be downloaded, so you can try.

      Ok, please don´t hesitate if you want to try to compile triax+Umat under windows.

        Hi Henning, but that would help. If you can please prepare the description, I will put it into installation instructions of Triax.

    IncrementalDriver can be compiled provided that the line 531 ends by 72nd column. This is the only bug I have noticed.

      Hi Krzysztof, thanks for pointing this out, Andrzej Niemunis confirmed the error and submitted corrected version, which is now in the download section.
