ERROR: Some boundary particle was excluded.

Hi there my simulation fails to continue due to an error:

*** ERROR: Some boundary particle was excluded. ***

TimeStep: 0.336181 (Nstep: 6029)

Total boundary: 37 (fixed=0 moving=0 floating=37)

Excluded for: position=37 rhop=0 velocity=0

Some boundary particle exceeded the +Z limit (top limit) of the simulation domain.

*** Exception (JSphCpuSingle::AbortBoundOut)

Text: Fixed, moving or floating particles were excluded. Check VTK file Error_BoundaryOut.vtk with excluded particles.

Could you please tell me a bit about this error?

  • Let us read through the error when step at a time. First line is:

    ERROR: Some boundary particle was excluded.

    So now we known that something is up with boundary particles. Then:

     TimeStep: 0.336181 (Nstep: 6029) 

    We know at which time step, and afterwards:

     Total boundary: 37 (fixed=0 moving=0 floating=37) 

     Excluded for: position=37 rhop=0 velocity=0  

    We are told that it is a floating object, with mk = 37 and that some of its particles was excluded due to position.

    And then the final line:

    Some boundary particle exceeded the +Z limit (top limit) of the simulation domain.

    You are then finally told that in your simulation a floating object exceeded your Z-domain limit. To change this look in XML and edit these lines:

    For example add "+100%" to z posmax. If you use FreeCAD, then look under the different options until you find Z-value option.

    Kind regards

  • Thanks a lot.
