Problem with 'Linear motion from a file' #68

Closed jpd03c closed 4 years ago

jpd03c commented 4 years ago

I am trying to complete the main example problem 07_WavemakerFile. I am following the youtube instructions: https://www.youtube.com/watch?v=ngCaODc0378

I get the following error:

ERROR: Some boundary particle was excluded. TimeStep: 0.000998 (Nstep: 4) Total boundary: 4 (fixed=0 moving=4 floating=0) Excluded for: position=4 rhop=0 velocity=0 Some boundary particle exceeded the +Z limit (top limit) of the simulation domain.

*** Exception (JSphGpuSingle::AbortBoundOut) Text: Fixed, moving or floating particles were excluded. Check VTK file Error_BoundaryOut.vtk with excluded particles.

Finished execution (code=1).

It runs normally if I use movement or a wave generator

This doesn't seem a bug, issue or feature request with DesignSPHysics. That video you're following has a few years and a bunch of things changed on DualSPHysics.

Your problem sounds like you haven't extended the Z limit of the simulation domain. You can do it on Execution Parameters -> Simulation Domain (at the bottom). -> Enable and change maximum position on Z to something to +30% and see what happens.

If you believe the error you're getting is due to a bug with this application please specify version, a zip file with your case folder and a way to replicate the problem.
