Short Description of Functionality

The program JANET is an interactive tool for generation and optimization of unstructured meshes.

JANET was developed by Smile Consult GmbH, Hannover (Germany). The software development is not finished yet, so updates are installed frequently.

Input-Files

1. Format gitter05.dat/bin (in JANET: TICAD systemfile ASCII!) The binary version of this format is not supported by JANET!
2. Binary mesh format of JANET: janet.bin
3. Smilesoftware binary format (.sbf)
4. TELEMAC Mesh format selafin
5. UNTRIM Mesh format untrim_grid.dat
6. TRIM Mesh format tr2.topo.bin
7. Structure line format of BAW insel.dat
8. Structure line format of BAW digi.gkk
9. TRIANGLE polyline format (poly)
10. Format geom.dat (in JANET: JANET ASCII format for {x,y,z} tripel data)

Output-Files

1. Format gitter05.dat/bin (in JANET: TICAD systemfile ASCII!)
2. Binary mesh format of JANET: janet.bin
3. Smilesoftware binary format (.sbf)
4. TELEMAC Mesh format selafin
5. UNTRIM Mesh format untrim_grid.dat
6. Structure line format of BAW insel.dat
7. Format geom.dat (in JANET: JANET ASCII format for {x,y,z} tripel data)

Methodology

New features in version 2.27.0:

• Analyses of a ship cross-section in a water body cross-section
• Computation of differences in depths based on subedges in an UnTRIM2 grid
• Automatic computation of the optimal depth interpolation
• Methods for surface sediments

Program(s) to run before this Program

CREATE_SIMPLE_UNTRIM2_GRID, DREHE2D, GISMO, GRIDCONVERT, POLYUMFORM, UNTRIM2007MONITOR

Program(s) to run after this Program

GRIDCONVERT, TICTRI, TOUTR, UTRPRE

Additional Information

Language

Java

Additional software

Java Runtime Environment

Executables

• Windows: janet.bat
• Linux-Workstations: janet

Starting JANET:

1. You have to define the PROGHOME variable on your machine.
2. You have to extend your PATH variable with the PATH of the executable script
3. You have to start a command line environment (DOS input box / xterm)
4. You have to type in janet [xxx]. The optional xxx is the size of memory in megabytes reserved for the Java Runtime Environment.
