Coupling FDM/FVM and SPH model
edited September 24
Is there a way to couple FDM/FVM with SPH in dualsphysics.
1. What is the purpose of such a combination? For which class of tasks?
2. There are a lot of publications about a combination of fems and sph
but I do not remember about/did not come across about coupling FDM/FVM with SPH
3. You can supplement the existing DualSPHysics code with your developments
DualSPHysics + SWASH
Altomare C, Domínguez JM, Crespo AJC, Suzuki T, Caceres I, Gómez-Gesteira M. 2015. Hybridisation of the wave propagation model SWASH and the meshfree particle method SPH for real coastal applications. Coastal Engineering Journal, 57(4): 1550024. doi:10.1142/S0578563415500242.
Theoretically, it is doable to couple SPH with FDM/FEM/FVM, you can google it.
There are many examples of coupling SPH-FEM and FVM-SPH.
You can find many papers and SPHERIC proceedings about that.
DualSPHysics is open-source, so you can couple it with FVM.
If you have any doubt, do not hesitate to contact us.

I am trying to simulate New wave (Tromans 1991) and High Order Spectral method (Douglas G. 1987) to study steep wave impact loads on floating bodies.
And I currently, looking for best way to simulate to efficiency to capture the loads on the body (If possible, also to save the computational cost).
For now, I will try to couple the Swash and DualSPHysics.
I am open for any additional methods or suggestions.
Thanks for the suggestions.
We are going to release the coupling between Swash and DualSPHysics in the next months...
In fact delegates of the
will have access to a first beta version of that...

we will give access to the attendees to download a beta version that includes:
i) Coupling with wave propagation models (SWASH, Relaxation zone, etc)
ii) Coupling with Project Chrono (Multi-physics)
iii) Open boundaries (Inlet & Outlet)
Great. Good to know that.
Also can you tell how to input the velocities to the boundary with different velocities at different positions. Like in the SWASH + DualSPHysics simulation.
Use external files with time & positions of the piston
