muffler with perforate -comsol
Hi!
can someone help me with the COMSOL? I need to mesh four-nodes muffler with perforate, but i am new in the COMSOL?
Thanks!

Matlab-based Digital Image and Volume Correlation Simulators
Hi,
I just posted a Matlab-GUI easy-to-use DIC and DVC simulator tool on our website (franck.engin.brown.edu) for download for anyone that works with DIC or DVC. The purpose of these simulators is to simulate deformation fields based on a user provided image (2D) or volume (3D), and evaluate the correlation results with the analytical solutions to provide quantitative feedback on the "goodness" of the provided images for DIC or DVC purposes.
Feel free to use them for research, teaching, etc. We welcome any suggestions for improvements, etc.
Lecture Notes on Micromechanics
Dear iMechanica community,
I have posted a set of lecture notes on the analysis of heterogeneous materials under MICROMECHANICS. The lecture notes include a collection of Fortran and MATLAB codes that accompany the computational exercises in Part II of the notes.

The ESAFORM 2013 International Conference on Material Forming
Dear Colleagues,
Following the last successful events in the past years, the next ESAFORM
Conference on Material Forming (ESAFORM 2013) will represent the 16th
edition of one of the most important and well-established international
research meetings on the material forming field. The conference will be held
at the University of Aveiro, Portugal, from 22 to 24 of April, 2013.
Abaqus: write surface mesh element detail
Hi,
i need some help in writing the surface mesh in abaqus. i have a wing model, meshed using hexahedral mesh. now what i want is to write the surface element detail on a file, containing the element number and its neighbouring four nodes. for example
12, 2 3 5 6
here 12 is the element number and 2,3,5 & 6 are the corresponding nodes.
EFG in LS-DYNA for crack simulation
Hello, everyone!
I am a graduate student in Hunan Univ, my research field is meshless method. Instead of using codes to calculate, I find EFG has been well developed in ls-dyna, and using software may be more convienient for me.
But I can only find some introductional information, so I want to find some useful material in iMechnica.com!

rotation spring setting
Dear all, these days I use combin14 to simulate the boundary conditions. I use two types of springs to simulate support. One is linear displacement spring, the other one is rotational spring. When the spring is on the radial edges, the rotation is about radius direction. When the spring is on the circumferential direction, the rotation is about circumferential direction. So i translate all the nodes to local cylndrial coordinate system. When the spring constants are large enough, the simulation results do not meet well with the clamped boundary conditions.
