Smoothing length and cut-off length
From the new CaseTemplate.xml for 5.0 I see there is a new parameter
<coefh value="0.866025" comment="Coefficient to calculate the smoothing length (h=coefh*sqrt(3*dp^2) in 3D)" /> <_hdp value="2" comment="Coefficient to calculate the smoothing length (hdp=h/dp)" />
According to the comments the smoothing length is two things:
h. In the Run.out there is another symbol
In Section 3.1 of the User's Guide https://github.com/DualSPHysics/DualSPHysics/wiki/3.-SPH-formulation
only kernels with an influence domain of 2 h are considered
Can you please clarify which is which? Is there any risk here that the notions of 'smoothing length' (length scale of kernel or suchlike) and 'cut-off length' (size of the influence domain or suchlike) are being confused? Hopefully these is some sense in making notation and commentaries consistent, in due course of course.
