Cohesive Zone Model in ANSYS
Hello Everyone,
I am trying to model a propagation of fluid-driven crack in ansys apdl and I have the following questions:

positional finite element
hello Dear friends
positional fem is introduced by H.B. Coda for studing geometrically nonlinear analysis of 2D beam. I need some information about implementing of this formulation.is there anaone who can help me.
best regards.
VUMAT of Drucker Prager, help needed please..
Hi Everyone,
I have written Drucker Prager in VUMAT version as shown below..but still there are some deviation with the original in built version of ABAQUS. I have all the notes how i derived these equation.could you please show me where the code has gone wrong or have i missed a critical point in here..i tried my best to spot the error but could not..may be you all experts could find it. Thank you very much.

Run Abaqus from a Java code
Is it possible to run Abaqus from a Java code? or is there any communication way between Abaqus and Java?
I want to simulate a simple problem and pass some info from Abaqus to Java code and vice versa.
Thanks,
XFEM for crack propagation
Hi
I am new in Abaqus XFEM and I am stuck at geting a crack propagation in XFEM ,working for my Master thesis, the crack doesnt propagate. In some examples its gets opened/widened, but its not propgating.
Can any one please advise me on this or help me with simple input file for checking.
I have attached a input file of mine , it owuld be of great help if someone could have alook and advise.
Thanking in advance
Thanks

EST method with GNU Octave
The EST method -- http://www.e-uni.ee/e-kursused/estmethod/ -- http://digi.lib.ttu.ee/estmethod/ESTmethod.pdf -- is a general computational method, for solving boundary value problems for the structural analysis of frames, beams, and trusses. Differential equations are considered here together with a set of boundary conditions. Compatibility equations for joint displacements and equilibrium equations for member end forces at joints serve as boundary conditions.
Case Study Effect of Pore Size on Pellet-Based Catalyst Flow
We have a new case study on our website based on research at Imperial College into multiscale tomography and calculating permeability for catalysts. The project involved studying the influence of pore structure on fluid flow across large length scales in silica-alumina pellet-based catalysts.
3D data at different length scales was obtained from XMT, DBFIB-SEM and ET scanning and segmented into a binarised dataset.
elastic follow-up
This is the story of threefold failure, which doubtlessly is the subject of fracture mechanics, a story of failure in various regards, however. First, it comments on an article dealing with failure assessment, second it reports on the personal failure of the blogger to understand this article, and finally it bemoans the failure of a seminal idea.
Chasing for “prey”, I came upon a contribution on the assessment of “crack-like defects under combined primary and secondary loads”, namely
