Hi,
I am a new comer to this forum (impressed and attracted me so much) which I came across through Googling.
I have one question about using user subroutine in ABAQUS. Can the user subroutine in ABAQUS call third partys DLL?
I have the ABAQUS input file (200foot.inp), the user subroutine UEL (UEL.FOR) and a DLL (CVFDLL). All these three files were tested and assumed to be correct (with the !Dec$ declarations). Everything is fine when the UEL does not use the DLL using the following command line:
C:\Temp>abaqus job=20foot user=uel interactive
But an error always occur when the UEL attempts to use the DLL. Ther error message is:
C:\Temp>abaqus job=20foot user=uel interactive
Abaqus JOB 20foot

Abaqus Error: Problem during linking - Abaqus/Standard User Subroutines.
This error may be due to a mismatch in the Abaqus user subroutine arguments.
These arguments sometimes change from release to release, so user subroutines used with a previous version of Abaqus may need to be adjusted.

To me, that means the DLL can not be located by ABAQUS and can not be linked to create the StandardU.dll. Is my understanding correct?
I tried:
1. add usub_lib_dir in the enviromental setting file (abaqus_v6.env) to direct to the path where the DLL is,
2. add /DLL:X:\path\CVFDLL.DLL to the link_sl= in abaqus_v6.env.
but neither works.
the first got the same error prompt and the second got similiar error message:
C:\Temp>abaqus job=20foot user=uel interactive
Abaqus JOB 20foot

Does anybody have some suggestions? Any comments will be appreciated.
thanks
