Look to update to barycentric tracking in the future.

old "positions" file form

The change to barycentric-based tracking changed the contents of the
cloud "positions" file to a new format comprising the barycentric
co-ordinates and other cell position-based info.  This broke
backwards compatibility, providing no option to restart old cases
(v1706 and earlier), and caused difficulties for dependent code, e.g.
for post-processing utilities that could only infer the contents only
after reading.

The barycentric position info is now written to a file called
"coordinates" with provision to restart old cases for which only the
"positions" file is available. Related utilities, e.g. for parallel
running and data conversion have been updated to be able to support both
file types.

To write the "positions" file by default, use set the following option
in the InfoSwitches section of the controlDict:

    writeLagrangianPositions 1;

The splash kinetic energy has been changed to depend upon the velocity
of the parcel normal to the wall, rather than the absolute velocity, in
accordance with the original reference.

Interpolated continuous phase data is only needed during a track and
therefore shouldn't be stored on the parcel. The continuous velocity,
density and viscosity have been moved from the kinematic parcel to the
kinematic parcel tracking data. This reduces the memory usage of the
kinematic layer by about one third. The thermo and reacting layers still
require the same treatment.

The patch can be determined from the particle when it is needed. Most of
the time it is not.

A lot of methods were taking argument data which could be referenced or
generated from the parcel class at little or no additional cost. This
was confusing and generated the possibility of inconsistent data states.

Will Bainbridge authored 7 years ago and Andrew Heather committed 7 years ago

Tracking data classes are no longer templated on the derived cloud type.
The advantage of this is that they can now be passed to sub models. This
should allow continuous phase data to be removed from the parcel
classes. The disadvantage is that every function which once took a
templated TrackData argument now needs an additional TrackCloudType
argument in order to perform the necessary down-casting.
