I am currently researching the
fluid-structure interaction (FSI) of fistula and av-grafts in the region
of the brachial artery in dialysis patients. I will be using ANSYS
Mechanical and FLUENT as the coupling offered is strong/implicit which
is necessary for my model. I'm having some trouble implementing the
anisotropic hyperelastic material model for the artery. This material is
in the 'Special Hyperelastic Materials' section and thus needs to be

Abrasive Simulation

Hi,

I'm trying to do simulation on Abrasive sand paper. I want to calculate the amount of material removed from the workpiece after some number cycles.

Can any one help me how can I start this simulation in abaqus.

ABAQUS/CAE

Dear iMecanica community,

with ABQ I'd like to create a mesh part without an associated geometry using the bottom-up-technique.

I already found the Python commands to add nodes to an orphaned mesh (from an inp-file).

In order to this I must first import an existing part and make node definitions on the orphan mesh part.

Is there a way in ABQ to define nodes, elements, etc. directly using scripting commands without

creating an orphan mesh part (by importing a model)?

ICE's Engineering and Computational Mechanics general call for papers!

Submitted by Rebecca Ratty on Wed, 01/08/2014 - 09:29

Dear Colleague,

Engineering and Computational Mechanics is currently looking for papers on the theme of Disaster and Hazard engineering for publication in 2014. Sub-topics include risk analysis and pre-emptive disasters.

Other themes EACM is interested in are: Fluid Structure interaction especially ringing phenomenon; Energy and renewable energy including offshore and waves; and review papers covering the themes in the call for papers.
