Question about the test '8_CASEFLOATING'

edited January 2017 in DualSPHysics_v4.0
Hello,

I meet two questions when recalculate the case '8_CASEFLOATING'.
1、Though the output options '-vars:+all' is active, only the velocity filed was NOT include in the output files (*.vtk ), why?

2、The displacement of cylinder in the reference agrees very well with the data 'EXP_FloatingSphereVal2D_Displacement_Fekken2004', but the displacement of my recalculation with the default definitions in xml file is much larger. So, is there any parameter special to be modified?

Thank you!

  • Please note first that Time(-) and Velocity(-) are non-dimensional values defined as
    T=t / sqrt (g/r)
    V=v / sqrt (g*r)
    being r the radius

    Does this fix the problem or not?

    Regards
  • Thank you, Alex,

    The problem NO.2 about the comparison is fixed according to your kind opinion. Here, r means the radius of cylinder.
    For the first question, how can I observe the velocity field? When i select 'vel' option in paraview, the velocity field is NAN.
