Thank you good sir

Anyone know why that particular solver was given a name so... difficult?

typical openfoam layers. There is a

kinematicParcelFoam

and this one is the incompressible uncoupled version You can go deeper with the dynamic mesh variant,

uncoupledKinematicParcelDyMFoam

🙃

this was actually one of the motivation of the foundation branch: refactoring code and decluttering solvers

Well yes, but why wasn't it named shorter like icoC1ParcelFoam? C1 for one-way coupling 🤔 assuming they wanted to reserve naming convention for two and four way coupled versions.. otherwise why not leave "uncoupled" out completely

I guess there is no such naming convention

Maybe it's just that inventing good names is difficult. The "field-based Lagrangian" is also not quite what I'd expect it to be.. anyways we live with what we got 🧑‍🏭

I think they go with full words in general.. You could have icoOnewayCoupledKinematicParcel .. But 1 way is just uncoupled (I think).. 2 way is coupled.. 4 way is called CollidingParcel which is derived from KinematicParcel Beyond Uncoupled, I think it goes into DPMFoam, not sure of the incompressible element in that case.. and then intra-parcel features get added in MPPICFoam

does anybody here use solids4Foam? i want to find alternatvies to create mesh without relying solelyl on blockMeshDict

I haven't worked with solids4Foam, but ig a valid polymesh would work in it . Try using cfmesh , it's much more easier to work with, you can make things in a CAD application and directly gives you a readymade polymesh

hmmm

You can use S4F using alternative mesh generators.

Ywah, i was relying on direct map interface logic for the longest and i had pigeonholed myself into thinking that

Though conformal is ideal

What mesh gen do you use?

I use mostly blockMesh / SHM since they are both suitale for most of my applications.

Shm with rbf yeah?

Is it stable

Could you show sone examples of shm cases pls

what is rbf?

yes it is (has been sofar)

The mesh interface method

Radial basis function

I know solids4faom supports ami, directmap, rbf, and gci

Rbf i heard is the stable route when dealing with mesh motion using snappy

FSI challenge, anyone modelled this? https://cdn.discordapp.com/attachments/726379477256634419/1480625962604298250/galloping_gertie.gif?ex=69b05be2&is=69af0a62&hm=0b6a990c6df3a1c588c1d5855569ff154c50c69784d1d62652a413c2d12db279&

I think the only analysis that you could realisticaly do is check if the eigenmoden of your bridge show self excitation for low amplitudes. But if somebody has a mesh morphing algorithm that can handle such large deformation would be amazing. Still for that you would also need to model damping quite well sooooo …. Would be amazing if somebody has the time and skill to pull it off

Haven't, but I've seen a few papers that have
