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).
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
http://hogwarts.ucsd.edu/~pkrysl/faesor
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.
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.
Thanks.

I am very interested in a postdoctoral position in computational mechanics, ultrasonics, applied physics, mechanical engineering, or electrical engineering. I am proficient in FEM, FDTD, Moments methods. Experienced in ultrasonic measurements that involve ferroelectric crystals, thin films, periodic structures. Please see attached resume.
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
Hello,
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
i have problem in writing matlab code for 3D element to find electric potential at each node
i have the tool surface and workpiece surface and i have to find electric potential in the gap b/w tool and workpiece,for that i assume it as a solid and i took the laplaces equation to find potential i.e
(∂φ/∂x)2 + (∂φ/∂y)2+ (∂φ/∂z)2=0
and the gap b/w tool and workpiece is divided into n layers and i have to find potential in each layer,for that i am considering it as a hexahedron octanory node element
Hi,
Does any body know if MATLAB functions and scripts can be called into an ABAQUS subroutine like UMAT?

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:
1. I would like to open ABAQUS CAE thought MATLAB (which i have managed to do with the dos('command')), and then run a script as well, through MATLAB. I am using MATLAB 7 and would preferably like to run the whole process thought MATLAB.
Hi,
I am using a X-FEM Matlab code found here http://people.civil.gla.ac.uk/~bordas/xfemMatlab.html"]http://people.civil.gla.ac.uk/~bordas/xfemMatlab.html
In branch.m/branch_node.m (both functions of radius r and angle theta) crack tip fields are defined...and questions arise.
% Functions
f(1) = r2 * st2 ;
f(2) = r2 * ct2;
f(3) = r2 * st2 * ct;
f(4) = r2 * ct2 * ct;
