question about abaqus

Hi guys

I want to simulate a problem with abaqus,but during runing of my project,percent of process not increas for axample when i change mesh sizes to biger runing go up to 50 % and when i change mesh sizes to smaller than the previos size,it occure again but in 25%

is there any one that know about this problem,i'm trying to solve it for 2weeks but i cann't.

I'm waiting for your suggestions...

hiii

i m, arun sahu student of IIT kharagpur.my mtech thesis is effect of dynamic loading on slope stability analysis in open cast mines.i hav startted my work using software ABAQUS.can i give velocity as input in abaqus?

and here i just want to give trapezoidal form of load up to 2 sec.so plz help me in these ...............

Hello

I do my thesis on bearing capacity of foundations near slopes, I use mohr coulomb plasticity with el asticity

but I cant understand what should I do and why my result is dependent on the mesh size and why when I refine elements near

foundation the bearing capacity of the foundation becomes smaller please help me how can I do this thesis

Eulerian boundary region
Could you tell me how to define inflow and outflow eulerian boundary in ALE? MY ERROR IS "An Eulerian boundary region cannot overlap a sliding boundary region"


Defined in the first interface surface, and then modify the inp file, change to add

REGION TYPE = EULERIAN



*SURFACE, NAME=SURF1, REGION TYPE=SLIDING

TOP,S4



*SURFACE, NAME=EULER1, REGION TYPE=EULERIAN

EULER1,S3



Then, I go on the File/Import/Model...inp.file  - when he fined warning



Can I retrive strain increment in ABAQUS with python?

Dear all,

I just finished extrusion process simulation in ABAQUS with the input of stress-strain data. Now I want to retrive the strain increment of certain element during each deformation increment. Surely one can write straininc to a *.txt file when simulating with VUMAT. But the simulation of extrusion will be extremely slow with VUMAT. So How can I get the strain increment when simulating with the input of stress-strain data? 

Best regards,

shiyao
