In this contribution (see http://arxiv.org/abs/1306.4385), we derive lower and upper bounds for Wachspress coordinates over any simple d-dimensional simple convex polytope.  Numerical results for the Poisson equation on nontrivial polyhedral meshes are presented that affirm the linear rate of convergence in the energy seminorm of the polyhedral finite element method.  Matlab code to compute the Wachspress shape functions and its gradient on convex polygonal and polyhedral elements is also provided.

These two papers (with one on beams and the other on plates) have recently been

hi,

 I am trying to model pullout behaviour in abaqus. i generated my 3d model with the help of texgen and i am applying velocity b.c.s to simulate pullout. I am expecting that NFORC beneath the point of applying velocity will give the pullout load. am i correct?. If not, wat will fetch my query?

if my sum up the reactions at the boundary i may not get the pullout load becoz of the frictional force between the fabric interface. 

hellow

i need  how to configue abaqus to fortran 

abaqus 6.11 pr3

intel visuel fortran 11

microsoft visuel 10

problem with : Problem during compilation - ifort.exe not found in PATH.

please !

Hi everyone 

I am learning the polycrystalline crystal plasticity and testing material in ABAQUS and UMAT. Now I am trying to build a RVE by using the truncated octahedrons as the grain shape or Voronoi tessellations.

For truncated octahedrons, I built a truncated octahedrons and assembled them into the grain aggregate in the .inp file, and assign orientations in the UMAT based on the part's name. However, I found it hard to define their interaction between grains. What is their interaction properties and how to define the contact pair in an automatic way?

The paper presents a thermodynamically consistent modeling of the non-linear multiphysics of ionic polymer gels based on the multiplicative decomposition of the deformation gradient. In particular, the deformations induced by the motion of ions under an applied voltage are viewed as distortions, similarly to growth-induced deformations in soft tissues. Furthermore, a consistent linearization of the model in the regime of small deformations is discussed. Finally, a finite element implementation of the theory is introduced and validated against experimental results.
