    Static Riks Convergence problem, due to large strain increments

    Thanks for the answer Mustaine! Yes, i didn't specify an ending criteria because i didn't know a priori what was the stopping criteria, because i wanted the force to increment until, more or less, plastic collapse occurs. My analysis must continue until the ultimate stress of the structure as...

    Static Riks Convergence problem, due to large strain increments

    Hi all, I have a model of a bi-dimensional sheet of hexagonal lattice of graphene, in which I define elastic-plastic material properties, with a boundary condition that constraints displacement in X in the left side of the sheet. In the right side, i apply a unitary concentrated force on the...

    Multiple analysis on the same model

    Thanks bartosz, now I understand how to use the load cases. I think in my case, i'll use 4 diferent perturbation steps with one load case each, as the boundary conditions aren't common to all analysis, as Mustaine said (thanks!) Should i create all the boundary conditions in the base step and...

    Multiple analysis on the same model

    Hi Bartosz, From what I've been reading, if I use several LOAD CASE's in one model for the same job, the outputted results are linearly superimposed. And what i wanted was four separate analysis of one of each particular load case, and not the result of a linear combination of all 4 cases...

    Multiple analysis on the same model

    Hi, I am building a model of a nano structure on Abaqus. The geometry is a simple hexagonal truss that makes a thin bi-dimensional plate, simulating the molecular links of graphene. In the same model, I want to make 4 diferent analysis, all static with diferent load cases and boundary...

    HOW TO: External Python Modules from Abaqus Python Interpreter

    The toolkit that i've download is sci-kit nano and it's latest release contains specific functions that I need in order to generate point coordinates of a nano structure, and this external module requires python 3.3. When i try to import it in abaqus environment, it gives me an invalid syntax...

    HOW TO: External Python Modules from Abaqus Python Interpreter

    I think not, because the problem isn't the numpy and scipy extensions, the problem is that it requires python 3.3 at least. My solution was to write the data to file using the spyder dev environment, and now read the datafile into an abaqus script. Thanks for clearing this out !

    HOW TO: External Python Modules from Abaqus Python Interpreter

    Hi, I'm having the same problem. I have abaqus 6.14 which runs on python 2.7, and im currently working with some data that is generated by an external module that needs the latest release of scipy, numpy, and , especifically, python 3.3+ . When i try to import the modules, there are invalid...
