I haven't had a look at your simulation setup, but do read about of this blog post:

Hopefully there will be some useful tips in the associated article.
Good luck!
Dear all,
I am attempting to determine the radial outward force (ROF) of an elastic structure which has been compressed by an outer rigid cylinder. The cylinder is comprised of SFM3D4R surface elements.
In reviewing what might be the simplest way to extract the ROF, I have attempted to use...
Hi calxx,
never came across errors with negative jacobians...
but, have you taken a look at the Abaqus documentation for modelling arterial layers? Checkout:
Abaqus Benchmarks Guide -> 3 Material Tests -> 3.1.7 Anisotropic hyperplastic modelling of arterial layers
from the documentation...
hi Simon,
currently away from my PC, so don't have access to the file. I would suggest getting in touch with your local support office directly, as they can make this file available and are great at responding asap.

Hi Dave,
Thanks for the input on meshing stents. Will be sure to try this out soon. Likewise, have you tried out the 'wrap mesh' plug-in? Its a great tool and definitely worth looking into (unless this is what you ment by 'coordinate transformation'...).
The next steps are infact to model...
Hi Dave,
Thanks again for the input! Hugely appreciated.
Quick update for all interested:
I do think that the issues I have been experiencing are due to the construction of the stent ring, and subsequently, the mesh generated on it. I constructed the geometry using SolidWorks (Equation...
Hi Guys,
Have made some progress towards getting the stent crimping model running:
Elements have been updated to C3D8I (as per the Abaqus Best Practices Guide), the mesh has been refined from 8830 -> 14,112 using Medial Axis Algorithm w/ Minimizing Mesh Transition (note: the meshing at the...
Hi Guys,
Thanks for the input!
@rob - I have added Friction as an additional Interaction Property, and the simulation now runs. [FYI: Tangential Behavior -> Penalty -> Friction Coeff = 0.1]. However, I'm at a loss for why the model requires this additional interaction. When looking at the...
Hi Guys,
I've been moving forward with the stent crimping simulations, but am unfortunately running into some problems which I cannot seem to resolve:
Currently, my simulation is a NiTi Stent Ring (3D Deformable Solid) meshed with C3D8 elements, and a Crimp Tool (3D Deformable Shell) meshed...
For those who are interested:
it appears that my issues were not due to MS C++ Runtime Libraries, but rather a bug with Abaqus 6.13-2 and 4th Generation Intel i7 Processors.
Hello,
I am currently attempting to install Abaqus 6.13.
Unfortunately, during installation the Microsoft Visual C++ runtime libraries were not properly installed. I get an error indicating:
"Microsoft Visual C++ 2005 SP1 and Microsoft Visual C++ 2008 SP1 runtime libraries installation...
Hi guys,
@sdebock - thanks for confirming my assumptions, and providing a little more insight into what is a 'rigid' surface/the actual benefits of using the RSURFU subroutine...much appreciated! I think for my purposes using SFM3D4R mesh elements, with properly constrained nodes SFM3D4R will...
Hello,
I am currently using Abaqus (6.12) to perform analysis on various stent designs. At the moment, I am attempting to generate a 'Crimp Tool' to apply a radial load onto a NiTi device, as used to package stents into delivery catheters (which could equivalently be used to simulate balloon...
