Hi,


I would need to simulate a two-phase (gas-liquid) flow with a compressible gas phase by means of SPH. The geometry is complex and it is given by stl files. Part of the domain boundary is moving and I have an inlet and an outlet as well. Are there any SPH codes (free or commercial) that I could use for this simulation?


Thank you for your help.


Regards


Manuel

Hi, Manuel!
Look at:

https://spheric-sph.org/sph-projects-and-codes
https://dual.sphysics.org/
https://wiki.manchester.ac.uk/sphysi....php/Main_Page
https://pysph.readthedocs.io/en/latest/
dual sphysics have most improved plugins for complex geometry processing

Hi ves,

thank you for your reply and suggestions.

I have already been trying to use DualSPHysics for my simulation. But I will need to implement the Inlet/Outlet boundary condition for multiphase flows, because this feature is not currently supported. However, the very good point is that I can import the stl files.

I had also a look at the documentation of PySPH. It is mentioned in Overview/Changelog that an STL importer was added in the version of November 2018. However, I was not able to find any examples with the import of a complex geometry. Do you know whether this is actually possible in PySPH? If yes, where can I find an example to learn how to import a geometry?

Thank you.

Regards

Manuel

I don't know how work with geometry in pySPH. You may link OpenFOAM classes for mesh reading with DuaSPH or pySPH. GMESH reader, some mesh generation software and other reader https://people.sc.fsu.edu/~jburkardt/.
You need only points from mesh

I have my realisation outlet bc for G. R. Liu books fortran code. This code simple and easy to read and modification

Hi ves,

thank you for the hints and the reference. I will have a look at it.
