Mesh Generator

Mesh Generator (Main Window)

A Mesh is generated with the following steps.

Breaklines and hole polygones are generalized

includes intersection points for crossing break lines
close neighbours / twin points are united to avoid sliver polygons and midget triangles
removes duplicate points and breaklines
removes Orphan points
increases / decreases line point density with respect to DEM information (smart line interpolation)

The resulting [...]

Mesh Quality Analysis

Mesh Quality Analysis
Input files:

Mesh (.ELE and .Node-files, or .SHP-file) , DEM as .BIL-file, Velocity distribution .VEC-file after first calculations

Output files:

Saved in the folder of the input mesh.

[Inputfile]+.qual.csv   …   Mesh statistics

[Inputfile]+.qual.shp   …   Mesh with per cell quality information

Further explanation can be found in Chapter 6 of [...]

Create Streamlines with Velocity Field files

Create Streamlines with Velocity Field files

Give a .VEC-file with velocity field information and a cross section as .SHP-file of the river which is almost orthogonally flow through.

The resulting streamlines are placed in the same folder as the input .VEC-file.

Velocity Vectors and Streamlines

Parameters:

Approximated discharge between 2 streamlines at the given cross section.

Attention: As TINs and [...]

Probe Results

Probe Results

Load a mesh and multiple parameter layers, which provide one value per cell each.

Provide a file with points or lines.

For each point or each line point the values of each mesh data layer are written in a .CSV-file

This is an easy way to get cross sections [...]

Create Velocity Vector Arrows

Create Velocity Vector Arrows

Creates a .SHP-file with arrows in direction of flow, based on .VEC-file information. The arrow length depends on the magnitude. E.g. 1m/s generates an 1 meter long arrow.  For better visibility the length of the vectors can be scaled by the magnitude length multiplicator.

Option 1:  Only 1 arrow in the middle of [...]

Convert mesh to grid

Convert Mesh to Grid and Subtract another Grid (optional)

Attributes from various files will be assigned to triangles of a mesh. The mesh,  given with .ELE + .NODE  files  will be rasterized and saved as .BIL-file(s) in an output folder. The distance between 2 grid points in x or y direction is given by [...]

Refine an existing MESH

Refine an Existing Mesh

An existing mesh,  given with .ELE + .NODE + .POLY files will be refined according to one of the following options until the maximum number of refinement steps is reached.

Option 1:  Refine a mesh dependent to already known velocity distributions and water level information

velocity and water level informations can be given as [...]

ELE to SHP

Convert Triangle Files (.ELE,  .NODE,  .POLY)  to  .SHP-files

Add attributes from multiple files as LAYERS for the .SHP-files

Use AREA, VEC, NODE, XYZ

Add a LAYER with the approx. TIME STEP limit according to the Courant-Friedrich-Levy (CFL) -criteria for each cell

Add 1 depth file (.NODE)
Add 1 velocity distribution file (.VEC)

.SHP to .ELE + .NODE +.POLY

Convert .SHP files  to Triangle-files (.ELE + .NODE + .POLY)

This is not just a simple converter. It enables mapping, exclusion and substitution filters. For every single cell.

MAPPING:

Add Elevation Values from DEM (if a .BIL-file or a FOLDER with multiple files is given)

EXCLUSION FILTERS:

Don’t convert cells
