Hi,

Hi Abaqus experts

I am hoping that you can help me getting a element user subroutine writen in fortran f90 to work in Abaqus. I have made the simplest 8 noded brick element element that i can think of. I has a zero thickness and only has some simple definitions of the parameters ESTIFF,RHS,SVARS and PNEWDT. I have made a model with one single element of this user element where the upper part is displaced from the lower part which are fixed.

When I try to run the model I get the following message in the log file:

"Abaqus Error: The executable C:\SIMULIA\Abaqus\6.10-2\exec\standard.exe
aborted with system error code 5.
Please check the .dat, .msg, and .sta files for error messages if the files

Attached is a tar archive for a Fortran 90 library to compute maximum-entropy basis functions.  I have used the G95 compiler. The manual in PDF is also attached and a html version of the same is also available, which provide details on how to install the code and its capabilities. This library was tested by Mike Puso last year, who interfaced it to DYNA3D and NIKE3D codes.  Note that I have added a .doc extension to the tar file (can not upload files with .tar extension).
