Fluid Structure Interaction

FSI issue in abaqus co-simulation: misaligned nodes

Hi everyone,

 I am performing FSI simulation under abaqus.

The simulation consists in a porous solid (elastic isotrope and homogeneous under Abaqus/explicit) filled by a non newtonian (viscous fluid under Abaqus/CFD). The whole is contained in a cubic shell in order to apply proper boundary condition.

The cube is pinned on one face and undergoes a compression displacement on the opposite face. I have defined an interaction condition between the solid surface and the fluid model surface so Abaqus can exchange information during Explicit and CFD simulation.

The simulation runs well until I diminish the element's size, then the simulation doesn't start and give me the following error message:

Fluid structure interaction with Abaqus

Hi,

 

I'm looking for tutorials or example problems on carrying out Fluid Structure Interaction simulations using Abaqus.  

I have a large amount of experience with Abaqus Standard however Abaqus CFD is very new to me.  Would anyone have the training course notes on either "introduction to "ABAQUS/CFD" or "FSI Simulation with Abaqus"? If so, I'd really appreciate a copy.

 

Thanks

Ted

                         Accurate Implicit Time Integration in Nonlinear Dynamic Analysis

Using an effective time marching procedure is an important aspect in the implicit finite element analysis

of nonlinear dynamic problems. Here, we demonstrate some of the difficulties that can arise through an

example involving contact chatter and fluid structure interaction:

Virtual Heart Surgery

1. We highlight a study performed by researchers using ADINA in which they investigated a computational approach to construct patient-specific ventricle models based on in vivo cardiac magnetic resonance (CMR) imaging for surgical planning and optimization. The study was motivated by the fact that the use of such computational models can help to assess different surgical hypotheses and replace empirical and perhaps risky clinical experimentation. For more information please see

2. We offer a very attractive academic package, for research and teaching, for university users. For more information see

Coupled Eulerian Lagrangian Analysis

Hi every one,

 I am in my final stage of my dissertation, which is about slamming analysis of boat hulls with help of CEL - in Abaqus. I am currently working in how to validate the results which I got. Is there any way except experimental method to validate the stress - strain results?

Please help me...
