bemol is a program that re-assembles model output files that are stored in # grids.Usage
# grids are briefly explained in this document and this presentation.
The averaging algorithm used by bemol is described in this PDF document.

|
| -src source-file(s) |
accepts from 1 to 40 RPN standard files. |
| -dst output-file |
destination RPN standard file |
| -core grid-core-file |
destination RPN standard file that contains only the
"core" (regularly spaced) portion of the grid |
| -coarse coarse-grid-file |
destination RPN standard file that contains spatially
averaged fields |
| -nbits nbits |
Number of bits used for compacting standard files
(eg. 12, 16, 24, 32). When nbits = 32, IEEE encoding is used. |
| -avg average-factor |
Averaging factor (2, 3, 4...). Computed automatically
if not given. Under automatic mode, the average factor is computed
as the ratio between grid spacing at the edges of the grid compared
to the spacing in the middle. This ratio is typically 4. |
| -ig3coarse ig3coarse |
The ig3coarse and ig3core
options allow the user to force the ig3 value that will be used to
define the deformation axes (>> and ^^). By default, on #
grids ig3=0 and ig4=0. By default ig3=1 will be used for core grids, ig3=avg for coarse grids. Using different IG3 allow the user to test different averaging combinations while being able to view them with programs like xrec. |
| -ig3core ig3core |
|
| -compress [auto / yes / no] (default: auto) | Switch to activate / deactivate the Lorenzo compression algorithm
introducted in the RPN standard files in 2005. If set to auto : If the source record is compressed,
the output is compressed
if the source record is not compressed, the output is not compressed If set to yes : Forces the compression of the output
records
If set to no : Does not compresses the output
records
