The type of binary data generated by MODFLOW-2000, MODFLOW-2000 GWT, MODFLOW-96, MOC3D, or MT3DMS depends on:
If you ran MODFLOW-2005, MODFLOW-2000, MODFLOW-2000 GWT, MODFLOW-96 or MOC3D on a computer with Microsoft Windows operating system, and you used the executable (.exe) program downloaded from the USGS Water Resources Applications website, please consult the following table on how to specify the binary data type.
Model | Version | The binary data type is: |
MODFLOW-2005 | 1.2 and higher | Binary (unstructured, non-formatted) |
MODFLOW-2000 | 1.2 and higher | Binary (unstructured, non-formatted) |
1.0 and 1.1 | Unformatted - Lahey Fortran 90 (LF90) | |
MODFLOW-2000 GWT | 1.0.3 and higher | Binary (unstructured, non-formatted) |
1.0 - 1.0.2 | Unformatted - Lahey Fortran 90 (LF90) | |
MODFLOW-96 | all | Unformatted - Lahey Fortran 90 (LF90) |
MOC3D | all | Unformatted - Lahey Fortran 90 (LF90) |
If you ran MT3DMS on a computer with Microsoft Windows operating system, and you used the executable (.exe) program downloaded from the MT3DMS website, please consult the following table on how to specify the binary data type.
Model | The binary data type is: |
MT3DMS Version 4.5, mt3dms4b.exe | Binary (unstructured, non-formatted) |
MT3DMS Version 4.5, mt3dms4s.exe | Unformatted - Visual Fortran & LF95 |
MT3DMS Version 4 used with MODFLOW-2000 | Binary (unstructured, non-formatted) |
MT3DMS Version 4 used with MODFLOW-96 or 88 | Unformatted - Lahey Fortran 90 (LF90) |
MT3DMS Version 3.5 used with MODFLOW-96 or 88 | Unformatted - Lahey Fortran 90 (LF90) |
The following table provides information on how to specify the binary data type based on the ACCESS and FORM specifiers and the type of compiler.
Compiler | ACCESS= | FORM= | The binary data type is: |
Lahey Fortran 95 | 'SEQUENTIAL' | 'BINARY' | Binary (unstructured, non-formatted) |
'SEQUENTIAL' | 'UNFORMATTED' | Unformatted - Visual Fortran & LF95 | |
Lahey Fortran 90 | 'TRANSPARENT' | 'UNFORMATTED' | Binary (unstructured, non-formatted) |
'SEQUENTIAL' | 'UNFORMATTED' | Unformatted - Lahey Fortran 90 (LF90) | |
Visual Fortran | 'SEQUENTIAL' | 'BINARY' | Binary (unstructured, non-formatted) |
'SEQUENTIAL' | 'UNFORMATTED' | Unformatted - Visual Fortran & LF95 | |
Unix System | 'SEQUENTIAL' | 'UNFORMATTED' | Big Endian - Unix |
