PLIC,MPLIC: New piecewise-linear interface compression schemes

Browse Source 
A new family of interface compression interpolation schemes based on
piecewise-linear interface calculation (PLIC). PLIC represents an interface by
surface-cuts which split each cell to match the volume fraction of the phase in
that cell. The surface-cuts are oriented according to the point field of the
local phase fraction. The phase fraction on each cell face — the interpolated
value — is then calculated from the amount submerged below the surface-cut.

The basic PLIC method generates a single cut so cannot handle cells in which
there are multiple interfaces or where the interface is not fully resolved. In
those cells, the interpolation reverts to an alternative scheme, typically
standard interface compression. PLIC, with a fallback to interface compression,
produces robust solutions for real engineering cases. It can run with large time
steps so can solve problems like hydrodynamics of a planing hull, with rigid
body motion of the hull (above). The user selects PLIC by the following setting
in fvSchemes:

    div(phi,alpha)      Gauss PLIC interfaceCompression vanLeer 1;

The multicut PLIC (MPLIC) scheme extends PLIC to handle multiple
surface-cuts. Where a single cut is insufficient, MPLIC performs a topological
face-edge-face walk to produce multiple splits of a cell. If that is still
insufficient, MPLIC decomposes the cell into tetrahedrons on which the cuts are
applied. The extra cutting carries an additional computational cost but requires
no fallback. The user selects MPLIC by the following setting in the fvSchemes
file:

    div(phi,alpha)      Gauss MPLIC;

Variants of the PLIC and MPLIC schemes are also available which use velocities
at the face points to calculate the face flux. These PLICU and MPLICU schemes
are likely to be more accurate in regions of interface under high shear.

Overview
========
+ W3 example case of hydrodynamics of a planing hull
Mesh
====
+ The example includes two different approaches for meshing the case
+ The first approach uses no cell refinement in the vertical direction
+ The second approach includes local cell refinement, producing a smaller mesh
+ Cell refinement can cause disturbances of the interface
+ Where refinement is present, PLIC-based schemes perform much better,
producing far less interface disturbance than the standard interface
compression scheme.
+ The first approach has the advantage of avoiding interface disturbances but
for the potential cost of a larger mesh than with local refinement
Experimental results (ref. 1)
=============================
+ Velocity = 4.598 m/s
+ Trim angle = 3.485 deg
+ Drag = 50.691 N
Numerical results mesh 1
========================
Without local refinement
+ Velocity = 4.598 m/s
+ Trim angle = 2.794 deg
+ Drag = 48.616 N
Numerical results mesh 2
========================
With local refinement
+ Velocity = 4.598 m/s
+ Trim angle = 3.027 deg
+ Drag = 47.987 N
Acknowledgment
==============
+ Thanks to Raffaele Ponzini, Ph.D. Eng. from CINECA, for kindly sharing the
W3 hull geometry and for his valuable insight into the science of ship hulls
