Curvature effect on nitinol aortic stent

high i am a student doing a project on curvature effect on thoracic stent. I want to curve the nitinol stent in abaqus. I am using RSURFU and doing static analysis. But am not able to curve it. Also when using implicit dynamic analysis with quasi static apllication my KE is high and comparable to IE. So can any body help me. Crimping and expansion is not a problem.

How to use multiple GPUs in ABAQUS command line?


I am new to abaqus command line and trying to solve massive explicit dynamics and steady dynamics models. I want to use multiple CPUs and GPUs to sole this. I searched on internet and found the syntax as:

c:\Temp> abaqus job=Job-1 cpus=16 gpus=1 input=file1.inp double interactive

Is this syntax correct, especially gpus part? or do I need to write some more command to use GPU, such as type of GPU or something like that? Can someone tell me what "double interactive" in above syntax means?

Any suggestions or ideas on how to simulate a drop test in abaqus?


I am working on a research to simulate a drop test of a package box with ceramic saucer inside. I am not proficient in abaqus so I am looking for some suggestions.

Till now, I created a hollow box with 2 mm thickness to represent it as a cardboard box and a disc for a saucer. I have material properties for cardboard and saucer. Then I assembled the model in abaqus such that saucer is touching box at the bottom; this was initial condition.

Linking Abaqus 6.12-3 + VS 2012 pro+ Intel Compose XE 2013

Hi there,


Recently I had lots of problem with linking ABAQUS and Fortran compiler together. I did all of the things which has been described in forums but none of them worked for me. Finally I found the solution.

I'm using ABAQUS 6.12-3, Visual Studio 2012 Professional and Intel Composer XE Suites 2013. For linking them simply follow these steps:

1- find the file ifortvars.bat and its path.

ABAQUS Reinforced Concrete Beam Model

Choose a channel featured in the header of iMechanica: 

Hi All,

I am trying to model a simply supported reinforced concrete beam with longitudinal reinforcement. I am using 8-node solid elements for the concrete, and 2-node truss elements for the longitudinal reinforcement bars. I have embedded the reinforcement bars in the concrete using an Embedded Region constraint. I am then applying a displacement at the midspan (deflection control). I am using the Concrete Damaged Plasticity model for the concrete. My model begins to run but will not converge. Some of the error messages that I get are:

Substructure Generation in ABAQUS


I have created a substructure in Abaqus. As output, I will like to see the substructure matrices (mass, stiffness and damping matrices). However, I'm only able to write the mass and stiffness matrices to an output file (*.mtx).

Does anyone know how to create an output file including both the mass, stiffness and damping matrices of the substructure? Below, I have shown what I have written in the input file (*.inp).

Thanks in advance,



Compatibility: Surface-Based Cohesive Behavior in UEL

Hi all,


I have been trying to model the surface interaction between two blocks of material using surface-based cohesive elements (*cohesive behavior). This works well in ABAQUS CAE (standard) when I set the material properties as "Mechanical, Elastic" so no problem with that.

However, I would now like to use the material properties from a fortran code. To do this, I was planning on defining the elements using *UEL with an overlay to record all the values. Is this compatible with cohesive zone elements? 


Recover wall clock time in Abaqus/Explicit

Dear All,

Does Anybody know how to recover the wall clock time of an Abaqus/explicit analysis? I do not understand why for implicit analyses is easy (log file) while for explicit there is no information.

Thank you,


Rotational Abaqus Direct Cyclic Boundary Condition


I am attempting to model the rotation of a cylindrical bar using Abaqus 6.12 coupled with the direct cylic approach. In my model I have one end of the beam fixed while the other has a kinematic coupling constraint to a reference point that has an applied rotation of 0.1 rad.

Hello everybody

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

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.

YOU COULD WIN: The Look What I Did Challenge

As we approach the last few months of 2013, it’s interesting to
reflect upon what took place over the past ten months. Reminiscing can
be fun, but do you know what makes it even better? Sharing memories for

how to model masonry wall in abaqus

here we are to tell you how we can model masonry in abaqus cae.

there are 3 ways:

1-micro modeling

2- macro modeling

3- micro-macro modeling(HOMOGENIZATION)

micro modeling; 

in this method all parts should be modeled in abaqus separately.

but notice that don't use shell to modeling grout because of 3d properties of grout and cohesive characteristics.

this method is suitable for small masonry panels with 2-3 layers of brick.

how to link abaqus with matlab ?

You should access the abaqus results (*.fil) file via MATLAB.

In order to take your results into a fil file you should specify
*FILE FORMAT, ASCII along with *EL FILE and/or *NODE FILE, etc. options
in your abaqus input file (assuming that you run Abaqus/Standard).

Abaqus python scripting, booleanmerge section assignment


 I am writing a python script for modeling aggregates in a concrete cylinder. I have created a all the particles and and specified section properties to them and to the  cylinder.

The procedure I am using is to merge the particles and the cylinder while retaining the boundaries. If the sctions are assigned to the parts before merging, the result is the cylinder with the specified section assignmentsfor each part.

I wrote the code in python but seems like it does not include the section assignment to the new part from merge.

PhD studentship position on "modelling of surface defects transformation in hot rolling of steel"

a PhD student ship is available for UK/EU nationals (ONLY) to develop a Finite Element model of the rolling
operation to predict the behaviour of surface defects on the rolled
material during hot rolling of steels. The effects of geometrical parameters along with the material
properties and the rolling geometry, such as bite angle, on the behaviour of
the surface defects during rolling will be investigated. The
project is partially funded by Tata Steel Europe,

ainsotrpic plasticity in Abaqus



Does anybody know how to input ainsotrpic plasticity in Abaqus?

I have an orthogonal elastoc plastic material and to input elastic properties I use engineering constants but to input orthogonal plasticity (not for all components)  I have no clue.


Thnaks in advance,
