Re: Interesting project: DesignSPHysics fluid simulator
The new DesignSPhysics-GUI is awesome !
create the case in 3D
define movement of one or more bodies
define physical and solver parameters (tons of options)
press „Change 3D/2D“ button ==> 2D case is generated, speeds up simulation
postprocessing
export fluid and body motion as vtk-series for paraview
generate csv-files for plotting forces and motion (x,y,z,pitch,roll,yaw) in excel
measure pressure at every point you want
a.s.o...all in one GUI
Thumbs up to the developer, great job!

Re: Interesting project: DesignSPHysics fluid simulator
and some more info...
Define body-motion + 7 additional wave-generators
Constant and execution settings
Runtime solver log
Define floating state of objects.
pretty complicated stuff...

158x27x16 m „containership“ with engine failure in heavy sea drifting to
the coast. The peak level of the blue force-plot (horizontal force on ship)
is the moment, when the breaker slams at the hull. Peak-level 617 kN
per m hull lenght. After running the simulation, you can generate a csv-file
of the forces/motion. The csv was imported into Smath-studio to do a frequency
analysis with FFT. The red plane in the model is the wave-generator,
the red slice is the 2D computing domain. Complete simulation was 60 sec
with 0,2 sec timestep. Number of points approx 11000 (rough...).
Runtime on quadcore-cpu Intel celeron 2 hours. I need this machine...

Have a happy new year!

Nice tutorial about sph-method:

https://www.youtube.com/watch?v=OTlygbegQT4
The dualsphysics-manual is for people who are familiar with sph.

Refresh this thread:
There is a Dualphysics macro.
Any interest?

Re: Interesting project: DesignSPHysics fluid simulator
Can anyone point me to a step by step tutorial on how to setup a problem and run it ?
Thanks
Michael
