Boundary Condition Implementing For DEM Particle

edited December 2018 in DualSPHysics v4.2
Hi everyone, I have problem that I want to DEM particle movement but When they face a specific boundary stop. For example in experimental case that I have vertical fluid dam and DEM object when run this case, I can write the code that maintain fluid particle in z<0.2 but DEM Particle Falling down to the bottom of there any way to prevent DEM particles stop falling when they face condition that z<0.2?<img src="" alt="" />

  • In version 4.2 of DualSPHysics do like this:

    Make a mechanical constraint which limits the movement of your DEM particle. In future releases with project cronos you should be able to do it just by code.

    Kind regards

    Dear Asalih3d, Thanks for your attention, can you advice me in source code? i want make a constraint that when DEM particle arrive the condition Z<0.2 the velocity of DEM particle be zero and movement of particle stop. but i cant discover Where the position of DEM particles is updated in source-code,can you advice me more?
    thank for your attention
  • in the source code i implement that code for fluid but i cant found where the DEM particle position update ?

  • @mtmtmt - very nice approach actually - but sorry, I have not spent time in the source code yet - I hope someone with more knowledge might be able to help.
  • I'm Very Thankful For your advice.
    best regards
