Hello everyone!

 I am trying to complete 2 separate analyses which i would love to get some advice on.

Hi everybody,

I'm working on UEL. The stiffness matrix (AMATRX) which I have
defined is consisting of complex numbers (real and imaginary part).

When I'm running it I'm getting this error message:

Abaqus Error: The executable standard.exe aborted with system
error code 1073741819. Please check the .dat, .msg and .sta files for
error messages if the files exist. ...

Hi everybody,

I have a UEL for truss element (T3D2). I'm calling and reading some .dat files inside of the UEL. I'm just reading these files inside of the UEL without doing anything to them or with them (It's just a test case). Here is an example:

      OPEN(101, file="C:\Users\ak1070\Desktop\UMAT-UEL-UELMAT\UEL TEST\V1.dat", status='old',form='formatted',&
                    &action='read',position='rewind')  
      READ(101,*) AEVectors(1,:)      
      CLOSE(101)

      .

      .

Hi every body,

I'm a new user of UEL and have a questions. It would be very kind of you to help me with it.

I have a MATLAB code which gives me some big matrices. Is it
possible to save them as a file (.txt, .dat, etc) and call them inside
of the UEL? (It's almost impossible to change all of those codes to
FORTRAN or copy-paste them to UEL.)

Thanks in advance,

Best Regards,

Hello,

I am having issues running an Eigen value simulation on a bridge model that I have developed. The model consists of a bridge super-structure supported by pinned connections on the ends of the bridge length and a roller support in the middle.

The model runs without errors when I do not request an Eigen value analysis, but aborts when I request an Eigen analysis. The message file sites the cause as a factorization error. Warnings also appear stating a zero pivot when releasing the 1st dof of the nodes associated with the roller connection.

Hi everybody,

I'm writing a User Difined Element (UEL) for my research.

Would you please let me know if it's possible to call a file (txt, dat, etc) inside of the UEL or not?

Example:

    IF (LFLAGS(3)=1) THEN
        OPEN (UNIT = 10, FILE = "AAA.dat", STATUS = "OLD")
        READ (10, *), StiffnessTable
        AMATRX=StiffnessTable
    END IF

Thanks in advance,

Ashkan

No worries! Check out the recording and learn how Abaqus FEA provides proven robust capabilities for modeling bulk fracture and crack propagation in many materials. One of the newest techniques available in Abaqus is the eXtended Finite Element Method (XFEM) whose advantages over alternative approaches include mesh independent crack definition, improved convergence rates for stationary cracks, simplified mesh refinement studies and more!

Hello

My aim is simulate the structural response of a plate with pressure applied under fire condition in abaqus

To that extend I know how the temperature variates in time (known T(t) t from 0 too 3600 sec) also I know the material properties and Sy to every temperature.

I thought that the best way to do this is by applying the T(t) as BC in the structure and use coupled temp displacement in one step.

But I don't know if this approach is correct.

Hi all,

 I am new in the blog, so I would like to appologies if this post is already published.

 I am doing a research in vibracion-based health monitoring based in CFRP beams. As a part of my research, I am modeling a composite beam in abaqus and apply transient analysis on it. Before I would like to validate my model with a very simple a easy model for this reason I have elaborated this procedure:

 Hi everyone,

I am a working on a cube in abaqus. I had to remove some nodes from the face node sets. To be specific edge nodes. I have defined a function in such a way that after removing them what I have is a list of node labels. I am scripting in python. Can anyone help me in extracting nodes back from nodelabels? 

Or is there any better way to remove some nodes from nodelist and get the modified nodelist ? 

Thanks 

Hello,

high i am a student doing a project on curvature effect on thoracic stent. I want to curve the nitinol stent in abaqus. I am using RSURFU and doing static analysis. But am not able to curve it. Also when using implicit dynamic analysis with quasi static apllication my KE is high and comparable to IE. So can any body help me. Crimping and expansion is not a problem.
