New release of Abaqus2Matlab: GUI, reading .odb and much more!

A2M GUI interface 

Dear imechanicians,

A new version of Abaqus2Matlab has just been released and I hope that it is of interest to you.

This new release constitutes a very significant step forward in the development of this well-known software to connect Abaqus and Matlab.

Application of Corotational Formulation

Hello,  I am a PhD student in Mechanical Engineering, and at the moment I am studying the co-rotational formulation from Criesfield's books.

I am looking for applications of the corotational formulation in ABAQUS or MATLAB; my supervisor suggested me it could be done in ABAQUS through a User Defined Element Subroutine, but being a new user to this software I don't really know from where I should start.

How to copy particular results from a text file to another in Matlab

!!!Hii every body!!! Wish you all a very good day!

I am searching for opinions how to copy particular results from one text files to anothers. (You may assume I have a text files , unformatted, like a paragraph, and then starts 3 rows and 2 columns numeric values. I have to delete all the characters/strings, just want those 3rows and 2 cols; or copy those 3rows and 2 cols, anyway... I want to extract those via Matlab). I know it may be stupid question nut I am confused :p :-)

Thanks in adv...

matlab code to create cohesive elements (or UMAT) in any 2D mesh

To use cohesive elements, normally user can add a layer of elements between neighbouring node pairs. This matlab code can help you to process that especially your FE mesh is irregular. The code, the initial .inp file and corresponding out put files are attached for a better illustration. The new generated cohesive elements won't cause any trouble in the element number. Also you can apply this code to generate new UMAT elements in mesh.

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).

please help me to solve mechanical engineering design problem of rolling contact bearing with matlab. thank u so much.

Journal of the Mechanical Behavior of Biomedical Materials now accepts MATLAB figure files

You can enrich your online articles by providing supplementary MATLAB figure files with the .FIG file extension. These files will be visualized using an interactive viewer that allows readers to explore your figures within the context of the article. The FIG files can be uploaded in our online submission system, and will also be available for downloading from your online article on SciVerse ScienceDirect.

Your preferences in scientific/engineering/numerical programming

Hello everyone,

I am working on a project related to helping the everyday researcher do his/her programming easier and faster.

I have done a fair amount of research work at OSU and have gotten a feel for the way they program on a daily basis, but realize that it could be and probably is drastically different on different parts of the planet. As such, I am here to ask the following questions (really, any opinion helps, so feel free to respond with whatever you want):

Simple Cell Traction Force Script for Elastic Micropatterned Substrata

Hi readers, 

 This is MATLAB code that was written by myself and collaborators that we've sought to make available to the wider research community. The program is intended to track the displacements of micropatterned dots on a substrate in a similar manner to that performed by  Maloney et al. in "Influence of Finite Thickness on cellular adhesion-induced deformation of an compliant substrata". Physical Review E. 2008.

MATLAB for thermal simulation

I'm currently studying FEA/CFD and BEM for thermal simulation of custom dies within custom package mounted on custom PCB with encapsulate material (epoxy). I getting familar with CFD concept which seem overkill from ANSYS IcePack (too expensive) but exploring BEM technology from E3D in france (via Vishay).

I have access to MATLAB from other company to try it out for thermal modelling (BEM).

Open-source finite element code

Hello everybody,

I just wanted to let those interested in Matlab finite element development and educational environments that the successor to the SOFEA toolkit is now available at

The toolkit now provides in addition to thermal and stress analysis (static and dynamic) also sample simulations from other fields, such as acoustics, nonlinear heat conduction analysis, electrostatics, small-strain plasticity, .... The toolkit now also includes an implementation of the Nodally Integrated Continuum Elements (NICE) which are quite effective for nearly incompressible mechanics problems.

The toolkit and the accompanying textbook are open-source and freely available. The book is also available in print.

Had somebody implemented the MMA or GCMMA algorithm (Svanberg) in the 99 lines Topology Optimization Matlab code(Sigmund)?

Hello everybody,

 I need some help. I have a lot of problems trying to implement the MMA or GCMMA optimizer in the Sigmund's Topology Optimization code (99 lines). Have you ever do that?. Please, is very important for my pregraduate thesis.

Macro in Hypermesh TCL code and Matlab

Choose a channel featured in the header of iMechanica: 

Hi all,

I need to create a macro in Hypermesh with a TCL programming code. I have two problems. I've had the code yet, but It's written in Matlab code, I've heard that TCL can talk to Matlab by DDE. The second problem is that I don't know anything about TCL code. Anyone can help me, anyway?


Many thanks

i just started reading Meshfree and will love to see a matlab code for it,may be for a simple Poisson Eqn.

To serve as a guide.

Thank you

Dear all,


I went through the forums and came across one similar topic, posted by alex_612 "Using Matlab to optimize the ABAQUS/Explicit FE mode", but with no replies. So I would like to bring this similar topic up again.

The problem:

XFEM: crack tip function derivatives


I am using a X-FEM Matlab code found here"]http://people.civ...

In branch.m/branch_node.m (both functions of radius r and angle theta) crack tip fields are defined...and questions arise.
