Hydraulic 2D structure are a hydraulic network type that represent a complete flow 2D model. As a part of a hydaulic network, its biundary conditions can be connected to other part of the network by hydraulic network link.

Create new Hydraulic 2D Structure

To create a new Hydraulic 2D Structure, the user has to select the map tool "Structure 2D":

With this tool, the user has to delineate the domain of the model by digitizing on the map. Note that a right click on an existing vector layer polygon feature allow the user to defined the domain by the polygon.

Hydraulic 2D Structure properties

The entry to Hydraulic 2D Structure is through the properties window of this element (see Hydraulic network).

The tool buttons on top right of the window under the name parameter allow the user to (from left to right):

  • Enter in the window to edit the flow model
  • Launch simulation, export simulation, or change settings of the simulation engine
  • Change settings of scalar rendering on the map: selection of the variable, color ramp settings and mesh frame settings
  • Change settings of vector field rendering: selection of the variable and vector displaying settings
  • Open the 3D view.

Editing the flow model

Once entered in editing, several pages allow the user to edit the flow model. The different pages can be chosen from the list on the left on the window. These pages are:

  • Structure: editing of the structure lines, holes, boundary condition, and mesh generation algorithm
  • Mesh Resolution: drawing of polygon associated with mesh element sizes, allowing the user to vary the resolution of the mesh
  • Topography: handling Digital Elevation Models to drap topographies on the mesh
  • Edit elements / Mesh quality: mesh elements editiging and mesh quality checking
  • Roughness: drawing of polygon associated with roughness value, allowing the user to vary the roughness of the model
  • Simulation Configuration: choosing ans setting the simulation engine

Settings for TELEMAC engine

To run TELEMAC simulation from Lekan, it is necessary to setup information in the following window:

If the TELEMAC configuration does not support parallelization, the CPU Usage count has to be set to 1.
