The Noddy Block Model now consists of a variable number of files all coordinated by a header file, with suffix '.g00' . Depending on whether deformable anisotropy and/or remanence are defined, files with suffixes up to ".g12" may currently be created by the Save Block Model-> Noddy Block Model menu item in the Tools menu. The individual suffices .g00 to .g12 contain column-row-layer (top layer first) ordered information as follows:
|
File suffix |
File Type |
|
.g00 |
header file for Noddy Block Format |
|
.g01 |
density values for each voxel |
|
.g02 |
susceptibility values for each voxel |
|
.g03 |
remanence declination for each voxel |
|
.g04 |
remanence inclination for each voxel |
|
.g05 |
remanence strength for each voxel |
|
.g06 |
magnetic anisotropy dip for each voxel |
|
.g07 |
magnetic anisotropy dip direction for each voxel |
|
.g08 |
magnetic anisotropy pitch for each voxel |
|
.g09 |
magnetic anisotropy strength of x-axis for each voxel |
|
.g10 |
magnetic anisotropy strength of y-axis for each voxel |
|
.g11 |
magnetic anisotropy strength of z-axis for each voxel |
|
.g12 |
look up table index of rock type (LUT in header file) |
Not all files will be generated by any given calculation, in fact they cannot all be created at once. For example, if deformable remanence is selected, files .g00, .g01, .g03, .g04 and.g05 will be created. If neither deformable remanence or anisotropy is selected, .g00, .g01 and .g12 will be the only files created.
Voxel models from other packages may be imported by first converting the format to the Vulcan format, which is simple but excessively large, or by directly creating a Noddy Block Model file set (.g00 and .g12 files only are required). The format for the .g00 header file is as follows, and can be easily copied and edited.
