Hi everyone,
Has anyone ever come across the treatment of radiation heat transfer in one-dimensional beams using FEM ? Convection and conduction are well established, but I was wondering whether radiation is still an open area of research?
Any links to publications would be very much appreciated, Thank you
Safety Engineering and Risk Management Debate 2012
Which one is better, MyAberdeen or iMechanica, for debating topics relate to safety engineering and risk management?
Hello,
I understand from word of mouth, as well as an extensive study/Master'sThesis (http://publications.lib.chalmers.se/records/fulltext/164269.pdf), that Abaqus XFEM formulation works, but that processing of results to obtain reported SIF (KI, KII, KIII, not sure about J, others) are in error due to apparent bugs in Abaqus's algorithm to calculate the SIFs.
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???
