Hi
my problem is that when I use print command in my subrutine VUMAT ,the results changes and sometimes abaqus stops with an error.
do you think is there any problem with my VUMAT or this problem is a routine problem with VUMAT subroutine?
thnaks for your help

Hi
my problem is to define initial value for solution dependent state varibales in Vumat.when I define them in .log file the same as help,it doesn,t work and the error is your'e defining initial condition for element zero while this elemet doesn,exist.what can I do for solving this prolem.
thanks alot

A review article of our research at IBM TJ Wason Research Center in piezoelectronic transistor, an exploratory device beyond silicon, is published in MRS Bulletin, Volume 37, Issue 11, November 2012, pp 1071-1076. Your future computer may depend even more on the mechanics.

Abstract
I am doing simulation of fiber reinforced composites, for that I have modelled a cubic REV. However , when I am constraining the opposite faces' node displacement sum to be 0 and coupling the nodes in each face in the direction perpendicular to the area, ANSYS is coming out . I have tried this on i7 processor with 8GB RAM system. I am confused if its a RAM problem or a model problem. If there are too many constraints if I apply coupling as well as constraint???
Subjects
1. Mathematical modeling of therapeutic systems at the nano-scale
2.Mathematical modeling of morphogenesis in biological systems
Duration: 24 months (12+12), ideally starting on Jan./Feb. 2013
Place: MOX Laboratory, Politecnico di Milano, Italy
Project: the grant is an early initiative of the newly developing European Centre for Nanomedicine (CEN)
Description:
A post-doctoral associate position jointly funded by the NIH and NOCSAE is available at the Thayer School of Engineering, Dartmouth College. This position will support research in biomechanics of the human brain in vivo and the mechanisms of traumatic brain injury in the context of sports-related concussion, using stereovision, image-analysis, and finite element modeling. Interested applicants please send a cover letter, CV, and a list of 3 professional references to Songbai DOT Ji AT Dartmouth.edu. This position will remain open until filled.
Postdoctoral positions are currently available at MIT's Department of Materials Science and Engineering for individuals with a strong background in atomistic materials simulations (both classical potential or first principles). Projects will focus on properties of heterophase interfaces and amorphous materials. There are no citizenship requirements associated with these positions. A Ph.D. in Materials Science or related field completed within the past 5 years is required.
