- Cause was checking "polyMesh/points" via an IOobject.
Short-circuit with a check for a polyMesh/ directory first.
Limit the check to the master-node as well to further reduce
load on the file-system.

ENH: improve per-step conversion times for foamToEnsight.
Old code:
Converting 11001 time steps
Time [0] = 0 Wrote in 1.53 s
Time [1] = 1 Wrote in 1.52 s
...
Time [100] = 100 Elapsed time 205.35 s
Updated:
Converting 11001 time steps
Time [0] = 0 Wrote in 1.4 s
Time [1] = 1 Wrote in 0.07 s
...
Time [100] = 100 Elapsed time 42.4 s
- Speedup by hashing test results from the first conversion step
instead of checking each time.
Check data on all nodes to avoid problems with incomplete writes.
------------------------------
BUG: moving mesh detection failed for foamToEnsightParts
- adjusted to agree with updated foamToEnsight
------------------------------
Note:
- foamToEnsightParts (serial) still has about twice the throughput of
foamToEnsight.
Renamed the original 'laminar' model to 'Stokes' to indicate it is a
linear stress model supporting both Newtonian and non-Newtonian
viscosity.
This general framework will support linear, non-linear, visco-elastic
etc. laminar transport models.
For backward compatibility the 'Stokes' laminar stress model can be
selected either the original 'laminar' 'simulationType'
specification in turbulenceProperties:
simulationType laminar;
or using the new more general 'laminarModel' specification:
simulationType laminar;
laminar
{
laminarModel Stokes;
}
which allows other laminar stress models to be selected.
Required to support LTS with the -postProcess option with sub-models dependent on ddt
terms during construction, in particular reactingTwoPhaseEulerFoam.
Individual inward-pointing faces are checked and if all faces are
inward-pointing the block is inside-out. These errors are fatal and the
message indicates which block the error occurs in and where in the
blockMeshDict the block is defined.
- bugfix (empty patches), and added detection of steady-state
scheme.
Caveat: when called via execFlowFunctionObjects will always produce a
zero field, since the oldTime field is not available for this mode.
Extrapolate internal field to walls for post-processing.
Uses as new syntax for handling the naming of multiple fields.
The input fields are selected via a wordReList.
For example,
fields (U "(T|k|epsilon|omega)");
The names of the resulting output fields use placeholder tokens for
flexibility. For example,
result zeroGradient(@@);
The '@@' placeholder is replaced by the name of the input field.
Eg,
fields (U T);
result zeroGradient(@@);
-> zeroGradient(U), zeroGradient(T)
Or,
fields (U T);
result @@nearWall;
-> UnearWall, TnearWall
NOTE:
The function object will skip over fields that only have
processor, empty, zeroGradient patches. The operation does not
make much sense for these, and it avoids inadvertently
re-processing fields twice.
- implemented using magSqr() instead of sqr().
For scalar fields they are the same, but can be useful
if this function object is extended for more field types.
- Default is a width of 8 characters, but this can be extended up to 31
characters via the '-width' command-line option.
- Now use a similar structure as foamToEnsightParts for the masking.
This reduces the clutter within the directory, makes it easier to
selectively delete some time steps (using shell commands).
- Added in a "time" information data in each sub-directory to
make it possible to reconstruct the case file with an external
script.
- Conversion of cloud data should now also work in parallel
(may need more testing).
- Support binary output for cloud data.
- Better avoidance of illegal ensight variable names.
But still partially incomplete (due to patch fields).
==================================================
Example of NEW file structure:
EnSight/verticalChannel.case # case name
EnSight/geometry # for non-moving geometry
EnSight/data/ # time-varying data
EnSight/data/00000000/
EnSight/data/00000001/
...
Fields are stored by name within the data/********/ directories:
EnSight/data/00000001/time # human-readable time info
EnSight/data/00000001/U
EnSight/data/00000001/p
...
EnSight/data/00000001/geometry # for moving geometry
Clouds are stored at the next sub-directory level:
EnSight/data/00000001/lagrangian/<cloudName>/positions
EnSight/data/00000001/lagrangian/<cloudName>/U
...
==================================================
The old structure was significantly more cluttered:
EnSight/verticalChannel.case
EnSight/verticalChannel.0000.mesh
EnSight/verticalChannel.0001.p
EnSight/verticalChannel.0001.<cloudName>
EnSight/verticalChannel.0001.<cloudName>.U
==================================================
Now the postProcess utility '-region' option works correctly, e.g. for
the chtMultiRegionSimpleFoam/heatExchanger case
postProcess -region air -func "mag(U)"
calculates 'mag(U)' for all the time steps in region 'air'.
