Overset grid in OpenFOAM

We implement the dynamic overset grid capability into OpenFOAM and use the technique to perform the simulations of ship hydrodynamics with moving rudders and propellers.

As a naval architect I must say: That's fucking awesome dude!

[@saeidhariri7182]

One of the best simulations I've seen.

[@Mojonixa]

This is an amazing simulation.

[@yannaingshin9198]

That is really amazing, man.

[@DVKajak]

Wow, that's absolutely impressive!!

[@rakgitarmen]

This is a piece of art.

[@samirsam2329]

Very nice work!!!

[@animallovers1250]

exelent. that so amazing

[@austineadah2843]

A tutorials from scratch will be good

[@user-yu9xt9yb7f]

amazing！！！

[@ajicandrael4843]

Wow... This is really amazing, may I know, what kind post processing do you use?

[@user-zy7be9mc8i]

厉害！

[@AljoschaNicolaiSander]

Very cool indeeed! is there any chance to get one's fingers onto the code?

[@rajibroy04]

Is there any alternative to the SUGGAR, possibly openSource ?

[@mateusalves9558]

Hello , really Nice simulation .
I am a student from Brazil and my conclusion work is about predict the resistance curves of a hull (First I am trying with one model of Series 60 in one velocity), and I want to know If I could talk to you about simulations on OF, It would really help me.
Since then, thank you!

[@mortezamohamadi4099]

Is it possible to simulate and calculate the hydrodynamic pressure on the front of the boat?

[@QingfengDuan]

Excellent work！看到过David Boger 和 Eric Paterson的FoamedOver，用的是 SUGGAR++加DiRTlib做overset grid， 请问沈兄的overset grid是如何生成与处理的呢，自己开发的openfoam lib么？如果是，请收下在下的膝盖

[@zhirongshen3212]

那个时候我从零开始写了这个从SUGGAR到OpenFOAM的接口，做法和foamedOver不太一样

[@xdelph]

nice

[@mihailyakovchuk1593]

What is a post processing tool with moving camera capabilities?

[@HugoSabbatino]

Did you use VOF for free-surface capturing?

[@zhirongshen3212]

Yes, it was VOF.

[@rezadwikaaulia3663]

hello, my name is reza, i'm from Indonesia
i like your simulations,
if i may help to you, for give me a way how you do to make this simulation from start until finish?
thank you

[@vladrudoy5578]

What’s your PC speck?

[@minhkhangphan9]

How many DOFs for the DTMB 5415M did you use?

[@zhirongshen3212]

All 6DOF were enabled in that simulation.

[@ruisun4271]

没想到啊没想到

[@ruosizha960]

这么屌

[@RiemannsBeard]

Excellent! I try to do something like that for my PhD thesis. Would you mind to point me in the right direction? any hint will be appreciated! Regards, Antonio

[@AhsanKhanPhD]

Thanks for your video :)
In OpenFOAM, I want to run the solver multiPhase/interFoam/RAS/floatingObject but by default it runs with a cuboid body, I have a cylindrical body in .stl format and I want to use it as a floating object.
How can I do this? I have been able to insert the cylindrical mesh in blockMesh by using snappyHexMesh, but how can I use the cylinder as a floating object? Thanks if someone can help me out, I am doing a univerisity project

[@SaulousHR]

Tienes que modificar el fichero constant/dynamicMeshDict. En ese fichero es donde tienes que definir las características del objeto flotante (cuboid, jointBody, masslessBody, rigidBody, sphere). Suerte
