mDBC - excluded particle error

lormal · June 2022

Hello everyone,

I'm trying to run a complex geometry with mDBC and i'm getting this error:

-------------------------------------------------------

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

TimeStep: 0.000000 (Nstep: 0)

Total boundary: 17540 (fixed=0 moving=17540 floating=0)

Excluded for: position=17540 rhop=0 velocity=0

*** Exception (JSphGpuSingle::AbortBoundOut) at ..\source\JSph.cpp:2472

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

-------------------------------------------------------

Nothing really new as an error. I thought I could fix that easily.

Trying to understand what I was doing wrong, I opened the Error_BoundaryOut.vtk in Paraview,, but not even a particle was shown. I tried to enlarge my domain by a lot, adding a few far points in the simulation.

But I'm still having the same error. Do some of you have any clue about what could be happening?

Best regards

Probably getting NaN values since the motion is too powerful.

Kind regards

I found the problem. The .stl files were too large (above 20 Mb).

Thank you for the advise, anyway!

Best regards

Edit: I spoke too early; actually it seems that was not the real problem, I will tell when I will solve it.

Yes, the error does not mention size

It is because the motion is doing something unexpected or that your simulation domain is way too small. Try adding +100% in all fields at the bottom of XML.

Kind regards
