Soft-soil Data Input
The input data can be categorized into three areas: basic, advance, and terrain. The
inputs for basic and advance are inserted within the solver arrays. The terrain data
is read from files.
- Basic
- Contains basic track geometries and soil information required for the model. In most cases, the basic data is enough to run a realistic track model simulation. This allows you to perform design studies of a track without needing too many details about soil properties.
- Advance
- Additional data that defines soil properties in more detail. The files are required only when the advance file trigger is on (BAS_OR_ADV=2).
- Terrain
- Files that describes the terrain (relief) with vertical and horizontal dimensions of the driven surface. The paths to the terrain input files need to be specified in the model.
Basic Files
Required input files:
| File Title | Filename | Comments |
|---|---|---|
| General Data - Part 1 | N/A | The data is received by the solver. |
| General Data - Part 2 | general.dat | |
| Link geometries | link_geometry.dat | |
| Basic soil properties | soil_properties.dat | |
| Basic properties of sinkage and shearing | sink_shear_basic.dat |
Advance Files
Required input files:
| File Title | Filename | Comments |
|---|---|---|
| Advance soil properties | soil_properties_adv.dat | These files are required only if BAS_OR_ADV=2 |
| Advance properties of sinkage and shearing | sink_shear_adv.dat |
Terrain Files
Terrain profile for I_COR=1 required file:
| Title of file | Filename |
|---|---|
| Terrain profile | soil_input_1.dat |
Terrain profile for I_COR=2 required files (NG files):
| Title of file | Filename | Comments |
|---|---|---|
| Terrain profile No. 1 | soil_input_1.dat | The actual number of the files is equal to the
number of the track group NG. The maximum number of files allowed is 10. |
| Terrain profile No. 2 | soil_input_2.dat | |
| Terrain profile No. 3 | soil_input_3.dat | |
| Terrain profile No. 4 | soil_input_4.dat | |
| Terrain profile No. 5 | soil_input_5.dat | |
| Terrain profile No. 6 | soil_input_6.dat | |
| Terrain profile No. 7 | soil_input_7.dat | |
| Terrain profile No. 8 | soil_input_8.dat | |
| Terrain profile No. 9 | soil_input_9.dat | |
| Terrain profile No. 10 | soil_input10.dat |
