Multiple, assistant researcher/research scientist/postdoctoral positions are available in a large, 4-year duration, Department of Defense program on “Release, Atmospheric Dispersal, and Environmental Fate of Liquid Agents”.  The effort is aiming to: (a) achieve a basic understanding of the physics of aero-breakup and dispersal of liquid agents in high-speed flows, (b) achieve a basic understanding of impact/spreading/absorption/reaction/evaporation of drops falling on various substrates, and (c) develop and validate computational tools covering the hierarchy of scales involved and purp

Online Registration & Abstract Submission Deadline: December 8, 2008

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!
