Information on Abaqus CFD

Hi everybody,

I'm going to do a degree dissertation on FSI using Abaqus CFD.
I'm now considering a simple case, a circular cylinder fully immersed in a fluid domain. In this simple case I consider the cylinder as rigid and fixed. I want to work out the forces on that cylinder. I know that this is possible using Abaqus CFD but I don't know how to do. Maybe it's a really trivial question but I don't know in a practical way how to do it. I have already performed the analysis but I don't know how to extract this result.

 

Thanks a lot

It is a simple proble.

The first model which is made ine the ABAQUS/standard is a
structure model

The second model which is made in the ABAQUS/CFD is the
fluid model

In each model you should define a ‘’fluid-structure
co-simulation boundary ’’ in the interaction module

I  hope this can help
you any way if you can send a email to me if you want (m.alinia@me.iut.ac.ir)

Lucia, 

We recently posted about coupling CFD/Structural on our SIMULIA Learning Community (www.simulia.com/learning).

Title: e-Learning: Co-simulation of Abaqus/Standard and Abaqus/Explicit: https://swym.3ds.com/#post:13030

Abaqus/Standard to Abaqus/Explicit co-simulation allows you to capitalize on algorithmic strengths of two analysis program.  Abaqus/Standard strengths include:
   - Unconditionally stable
   - Allows for larger time increments than Abaqus/Explicit
   - Substructuring 
   - Cost-effective for small-strain analyses
Abaqus/Explicit strengths include: 
   - Excels at simulating high-speed events 
   - Extremely robust contact algorithm 

Co-simulation provides a cost-effective solution when different model regions can benefit from the respective strengths of the two analysis program.

 

Thank you Alinia and Rene.

 As you know is it possible to have Drag e Lift as an history output from Abaqus? How can I have this output? 

I'm now considering only cfd model (so a fixed cylinder) cosimulation will be the next step.

 

Thanks

Regards, Lucia 

I would like to model a two phase flow (water and debris) in
a deformation pipe. Can I use Abaqus CFD to model the two/ multiphase flow. If
not,
  can you provide any
suggestion/example/reference about a suitable CFD code that can couple and
cosimulate with ABAQUS standard/explicit?

 

Thanks for your help.
