How to simulate non-Newtonian fluid

I want to simulate non-Newtonian flows. Can you give me some suggestion about how to modify the code, especially viscosity treatment?



  • Correct me if I am wrong, but you only need to modify the case file .xml to simulate non-newtonian fluids. I do not know what exactly had to be modified since I did not do it myself. I would suggest looking at the latest .XML guide.
  • As a starting point, I highly recommend:
    1. The multi-phase documentation on the DualSPHysics GitHub Wiki for background theory
    2. Guide_CaseTwoPhases.pdf, which is included in:
    (2.) will give you a good idea about what you need to do to manipulate the XML. I recommend creating a new project based on CaseTwoPhases_FINE_Def.

    Do keep in mind that DualSPHysics v4.4 is scheduled to be released two days from now, so it might be best to start your project from the multiphase example(s) given in the new version of the code.

    And if you haven't read it yet, I would also recommend Fourtakas and Rogers, 2016
  • Hi @bladomas1 and @NWRichmond,

    Thanks for the advice. I'll give it a try.
