Dear All,

As FEA is one of the most popular methods for the treatment of contact problems. In that, the overall contact surface is discretized a number of segments and contact integrals are evaluated in a segment-wise manner. In 2005 Fischer and Wriggers [1] presented an integration method which avoids the need of contact surface segmentations and enables the evaluation of contact integrals directly at the slave nodes of contact bodies. 

A ``small'' but interesting riddle from the basic theory of vibrations. Haven't run into it in any physics/classical mechanics text/reference.

Hello ,  I have a small query. I'm unable to figure out the proper boundary condition to be assigned for an all side clamped plate under uni-axial and bi-axial buckling load. The plate is assumed to be under a pre-buckling uniform stress distribution over the laminate thickness.

Implementing J. Dolbow T. Belytschko MATLAB code of EFGM for CFD pronlems where more than one partial differential equations are involved such as continuity, momentum and energy equations. 

Can anaybody share the MATLAB code for a heat transfer problem of EFGM method using Penalty method for implementing boundary conditions.

Thanks & regards

I followed the following link http://read.pudn.com/downloads92/sourcecode/math/356902/EFGNumericalImp… for EFGM programming. For a Poisson equation whose domain is a square domain with unknown variable "U" is given zero on "Right vertical" and "Top wall" of the square domain.

We’re happy to bring you the latest version of Simpleware. The M-2017.06 release includes new features and performance improvements across the 3D image to model workflow. We have added new segmentation tools, enhanced the visibility of measurements, and introduced a new landmark registration tool for positioning CAD models in image data. The release also provides new improvements to our outstanding meshing capabilities.

For a mass diffusion test ,I want to introduce solubility in function of pressure

How can i do it?
