Hi all,

     Here I encoutered a error in ABAQUS when I include ALE with VUMAT. When ALE was not included with VUMAT, my job can work well while with the combination of VUMAT and ALE, the job cann't work any more due to a "Signal 8" error. And if I use a built-in material model and at the same time ALE, a job can work. Furthermore, element failure is considered in all of the cases.

    Anyone can give some suggetion? Thanks in advance!

Hi all,

     Can anyone give a description on the diffrence of ALE in ABAQUS and LSDYNA? And also the difference between r-adaptivity and ALE in ABAQUS. It seems ALE in ABAQUS means the same with r-adaptivity in LSDYNA while “ALE” means diffrently in the two codes.

      Thanks a lot!

When I implement failure model into AUTODYN by user subroutine, I fonud there are some differences between  results come from subroutine and  the results computed by AUTODYN'S provided material model. Is there anybody who is kind enough and familiar with AUTODYN's user subroutine to help me? If possible, an example of a failure model(for example, Johnson-Cook failure model) is highly appreciated.
