Stiffness Matrix (AMATRX) with complex numbers in UEL

Submitted by ashkan khalili 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. ...




I checked the files and no error message was found.


When stiffness matrix is just real numbers, it's working perfectly.

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',&

Question about UEL

Submitted by ashkan khalili on

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

Submitted by ashkan khalili on

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,

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.
