STAR-CCM+ and ABAQUS coupling is way more easier and user friendlier. There's some well explained tutorial in STAR-CCM+ about FSI and coupling of these two softwares together like " Abaqus Co-Simulation: Mechanical Coupling ", " Abaqus Co-Simulation: Thermal Coupling ", " Abaqus File-Based Coupling: Exhaust Manifold " and etc.

Dear Javad

One of the most important benefits of ADINA or new versions of ABAQUS is the simultaneous solution of Eulerian and Lagrangian equations. Does STAR-CCM+ and ABAQUS have simultaneous solution?

Furthermore, why STAR-CCM+ and ABAQUS ?

Only ABAQUS can support FSI simulation.

dear seifollah

i have simulated a usual problem ( whit abaqus 2017) . It had run for more than 25 hours. but my friend who used ansys in similar problem got answers in 2 hours in other hand there was lots of problem to view results in abaqus. I don't know ADINA but i prefer to use ansys not abaqus for FSI simulation.

Dear hosein

This results are interest

Thank you

Yes STAR-CCM+ and Abaqus run simultaneously. The coupling between STAR-CCM+ and Abaqus brings the solution of a wide range of FSI problems within reach. In terms of both practicality and accuracy, co-simulation (in which both codes exchange data as they simultaneously run) is one way to tackle problems such as aerodynamic flutter, fluid induced bending, vortex induced vibration, and galloping and etc. Star ccm and Abaqus is way more stronger than Abaqus itself for solving Fluid mechanics and all related interactions which both Eulerian and Lagrangian multiphase solver are available . In marine industry everyone is marching for this software! as it give more accurate responses and has a relatively reasonable run time.

Dear Javad

Is STAR-CCM+ open source?

Unfortunately it is not an opensource code like openFOAM.

Is there textbook or sources for teaching this software?

Is it easy?

One can be professional by just it's tutorials! It has a really widespread tutorials in many fields each one is step by step well explained. You can find those tutorials from: Help/Tutorial Guide/Simcenter STAR-CCM+/Tutorials

How do I define a non-Newtonian fluid in the ABAQUS? For example, cason model.

The upon question is very interesting for me

I use ADINA since may years also with FSI for internal and external fluid flow applications as well as in subsonic and supersonic flow regime with very valuable results.

Dear Seifollah,

I can try to give some insight, but I don't know if I interpret your question correctly.

ADINA-FSI is a package that couples the ADINA-Structures code with the ADINA-CFD code, so that you can do transient FSI analyses. The two domains can be arbitrarily non-linear, for example, and the Bathe composite time integration scheme has proved to be efficient and reliable. ADINA-FSI was the leading FSI code 10-20 years ago.

Besides that, a great number of FSI analyses are conducted in the FE codes (ADINA, ABAQUS, ANSYS, NASTRAN, etc.) as vibro-acoustic analyses (in time and frequency domains). But, I guess that you refer to FSI as the previous case.

Other FSI packages are available, Star-CCM+ can be coupled to ABAQUS, ANSYS can be coupled to FLUENT, and CFX I guess, and some years ago I saw the MpCCI FSI Mapper that could couple several codes, I have not followed it since. Star-CCM+ has its in-built FSI capabilities also. Many possibilities have surfaced the last decade.

I guess that it depends what codes you have available at your hands. CFD and FE codes, plus coupling code, can be very expensive. And, if you are already familiar with a code (CFD or FE), it may be obvious how to proceed into the multiphysics field. I have worked with ADINA Structures for many years, and for me it was not a big step to use ADINA-FSI, with the same GUI and handling.

Good luck!

Best regards, Kenth

Dear Kenth

Thank you for your comperhensive response

I use ADINA_FSI.

ADINA has strong solver that converge very quickly, But isn't user friendly. And in the post processing is very limited. Although convergence may be difficult in ANSYS, I prefer to use ANSYS.

Does anyone compare the result of a similar FSI problem in ADINA, ABAQUS and ANSYS softwares?

Has anyone FSI simulated with the COMSOL software?

Dear Esmaeel

Will the Lagrangian and Eulerian equations be solved simultaneously in ANSYS Fluent and ANSYS CFX as well as ANSYS Aqwa? ADINA can solve simultaneously

Dear Esmaeel

Thank you for your help

It completely depends on your problem and type of mesh that you want to use, but as my own experience, I prefer to use abaqus because Abaqus designed to be able to couple with STAR-CCM+ and CFD solver of STAR-CCM+ is significantly more powerful than the aforementioned software. So I suggest you to use co-simulation abaqus and star-ccm+

take a look at bellow link

Dear Aref

Thank you for your response. My experience is related to FSI simulation in biology and medical science. However, will the Lagrangian and Eulerian equations be solved simultaneously in abaqus and star-ccm+ ? ADINA can solve simultaneously and it is important for me.

yes, they can, I suggest you install star ccm and take a look at the help and tutorial guide of that.

BUT

the other software which can i suggest you to try is Comsol, i think Comsol is more prestigious software in the field of biology and multi-physic problem.

I hope the below links be useful for you (use vpn to open the link)

Thank you very much Aref

Hi !

Sorry to dig up an old post, but I would like to add something I think is important.

ADINA FSI solution can work with both iterative/segregated solver and a direct solver (were fluid and solid are solved in the same problem, in the same matrix), also called the monolithic approach. StarCCM+ and Abaqus can only solve FSI problem using segregated approach where the fluid and solid solver talked together.

Sometimes FSI solving face difficulties using segregated approach, in which case you will prefer a direct solving. Such difficulties are linked to the added-mass effect.

I'm using ADINA FSI solution to simulate a cardiac valve, and have no difficulties with it so far with a direct approach.

Hope that might help !

Thanks Alleau
