XFEM for rock in ABAQUS

Submitted by kianoosh on

Hi


I tried to simulating crack propagation with XFEM method  in porous media (rock),  but got error code 144 (like this error" the executable C:\SIMULIA\Abaqus\6.9-1\exec\standard.exe aborted with system error code 144. Please check the .dat, .msg, and .sta files for error messages if the files exist. If there are no error messages and you cannot resolve the problem, please run the command" )

I think abaqus 6.11 can't simulating crock propagation with XFEM method  in porous media , is it true?

Create new ( multiple ) parts from existing (single )part in Abaqus

Submitted by sidk1984 on

Hello Everyone,

i am kind of newbie to Abaqus, in learning phase. My question is regarding creating new parts from existing part in abaqus, kind of splitting activity similar to slice feature in ANSYS Designmodeler. As far as my regular activity in Ansys workbench, i require to slice body in designmodeler, to create new volumes, to refine mesh, or to define contacts with different status.have limited access to modeling software, so basically work with simulation software pre processor.

common block in abaqus user subroutine vufield

Submitted by PaulK on

Dear friends,

 

I am working on vufiled subroutine for abaqus. I already have a named common block statement in my vfriction subroutine. I need the values from the common block be read in vufield subroutine and passed further / saved to a field variable to be able to plot a contour plot.

Can anyone share his ideas about the coding or have an advice for me?

Abaqus help

Submitted by Amdebrhan M. on

Dear all,

I'm doing a dynamic analysis and optimization of high speed railway bridges. After developing the abaqus input file (*inp), the following errors have occured and I was unable to solve them. I have attached a picture showing the node number that I used to model the train. the car body and the bogies are model as a rigid body in which nodes 6001,6004 and 6501 are the reference nodes. 

1. An overconstraint problem. it says "Zero pivot when processing Node 6004 d.o.f 2, node 6004 d.o.f 6 and node 6001 d.o.f 6

Abaqus step definition

Submitted by vjgoudar on

Hello everyone.. Consider a cantilever for sequential load steps in abaqus.

Fist step I want to apply imposed displacement of 2mm at free end.

2nd step I want impose +/-6mm Z displacement at free end (total 3

cycles. (One cycle= +6 and -6 mm in z direction)



Can somebody let me know how to do this. how to define two steps ?

Thank you in advance
