1073741819 error code in ABAQUS

Dear all,

I'm using UEL in ABAQUS. The UEL works perfectly as far as I have 256 time increments (each 1e-6 sec). When I'm trying to increase the time increments (let's say 512 with the same 1e-6 sec per increment) Abaqus gives me error code 1073741819.

I'm running Abaqus 6.14.2 with Intel Fortran Composer XE 2013 on a Windows 7. CPUs are 3rd generation.

I would appreciate if you could help me to figure it out.

How to define RHS in UEL for a static analysis?

Hi every one!

I'm working on developing a shell element to be implemented in ABAQUS through UEL.

It's going through a static analysis. and as you may know for static analysis, ABAQUS just needs AMATRX and RHS to be defined via UEL. It must be mentioned that the stiffness matrix is changing at each time increment. The force that has been applied, is a concentrated force and a function of time.

I've defined the RHS as:


where [K] is the stiffness (AMATRX) matrix and {u} is the displacement vector at each time increment.

Node rotation in UEL definition

Hi everyone,

I'm working on UEL and recently I've developed a shell element. To define an element in input file, I'm using counter-clockwise rotation for nodes. When it's just one element everything is good.

Problem in printing out the global stiffness matrix

Hi everyone,

I'm using UEL in ABAQUS. My model just has one 4-node element (defined in UEL) fixed in one end. When I'm running the UEL, it's working without any problm. But when I' trying to print out the global stiffness matrix I'm getting this error: "aborted with system error code 1073740940".

This is the way that I'm trying to print it out:


Beam Elements, UEL, ABAQUS, Rotation

Hi everyone,

I'm working on UEL and studying wave propagation in beam. I have a special purpose beam element defined in UEL which has four nodes.  When the beam is horizontal and a vertical load is being applied, it's working perfectly:

      1,           0.,           0.,        0.
      2,         0,           0.25,        0.
      3,           0.,           0.,        0.
      4,         0.,           0.25,        0.

1073740940 error- ABAQUS

Hi everyone,

I'm using UEL and I'm getting this error when I'm trying to run the job "aborted with system error code 1073740940". Does anyone have any idea how can I fix it?

I'm using ABAQUS 6.12 with a core i7 PC.

I would appreciate if you could help me with this.

Global Stiffness Matrix-UEL

Hi everyone,

I am working in UEL. I can get the stiffness matrix from fortran to be printed in .msg file.How can I print the global stiffness matrix of the model by using ABAQUS. My model is not big or complicated, so the global stiffness matrix shouldn't be too big!

One time calculation in UEL

Dear All,

I'm a new UEL user. In my UEL I have a big Matrix which eigenvalues and eigenvectors of these matric is needed. the matrix is not changing during the time and it has constant elements. As you may know, calculating eigenvalues and eigenvectors is a time consuming procedure. In every time incerement, ABAQUS calculating eigenvalues and eigenvectors with bunch of other things in UEL.

Linking between MKL, LAPACK and ABAQUS

Hi everybody,

I'm an ABAQUS UEL user. I have Intel Parallel Studio 2013 installed on my computer with Visual Studio 2013 and ABAQUS 6-12.3

I'm almost a begginer in this area. I realized that Intel Composer XE 2013 (which has been intalled on my machine) contains MKL which has BLAS and LAPACK libraries in it.

I tried to use some of their functions (let's say eigenvalue solver and SVD solver). When I'm
trying to run it (abaqus job=test user=test1 int) I'm getting this error

Beam elements in Abaqus

Hi every body,

I'm tring to make a beam by using beam elements in Abaqus like this:




Stiffness Matrix (AMATRX) with complex numbers in UEL

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. ...

Questions about UEL

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',&
      READ(101,*) AEVectors(1,:)      




Question about UEL

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,



Calling a File inside of the UEL

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?


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

Thanks in advance,


Linking Abaqus 6.12-3 + VS 2012 pro+ Intel Compose XE 2013

Hi there,


Recently I had lots of problem with linking ABAQUS and Fortran compiler together. I did all of the things which has been described in forums but none of them worked for me. Finally I found the solution.

I'm using ABAQUS 6.12-3, Visual Studio 2012 Professional and Intel Composer XE Suites 2013. For linking them simply follow these steps:

1- find the file ifortvars.bat and its path.
