(https://www.eclipse.org/eclipse/news/4.7.2/)

• drag an external file (ESRI shape and Images supported for now) into the map
• drag layers within the outline view

• Meshing, setting up boundary conditions, simulation setup
• In-bound simulation triggering
• Support of parallel simulation triggering
• Export of prepared jobs to dedicated locations to modify steering file and add options/settings, that are not supported by Kalypso
• Import simulated jobs
• Integration of results evaluation procedure of Kalypso, i.e. full support of features allowed for RMA and Hydro_AS-2D
• Restarting from Telemac results or any other results

• Delauney conforming meshing
• maximum angle constraint
• fewer triangles using same settings as for Triangle

• Consideration of boundary polygons, breaklines, forced nodes, holes (such as buildings)
• Refinement polygons
• Import of features from e.g. shape-files via context menu in map outline
• adding, deleting, re-shaping of conceptual model features
• separate consideration / exclusion of features during meshing

• Added option to select meshing algorithm from Triangle / aCute
  • sweepline
  • divide and conquer
  • Incremental
• Added snapping tolerance to adjust inaccuracies in base (conceptual) mesh data
• Added different meshing options to attach projected triangulation to existing mesh. Allowed are:
  • Ignore mesh: New meshing will be done without considering existing elements. When finalizing the mesh all elements that intersect existing mesh parts will be refused.
  • Add mesh boundary as breakline: Meshing will be carried out as in "Ignore mesh", but boundaries of exisiting meshs will be extracted and considered with all nodes.
  • Patch to existing mesh: All overlaps of existing mesh and triangulation polygon will be erased to obtain a new meshing boundary.
  • Patch to existing mesh with extra boundary: Same as "Patch to existing mesh" but puts a buffer around.

Those tools are still in testing phase. The key issue is that on the neatline to an existing mesh no additional nodes (Steiner nodes) are desired on arcs, whereas on outer boundaries they are desired. Please make your own experiences. We are going to eliminate the options in further versions after finding the best procedure in our opinion. Any hint on user or developer mailing list is welcome.

• Allow for enabling / disabling specific mesh validation rules
• Added further net validation options
  • orthogonality
  • smoothness

• Newly, elements can be generate based on given river axis and flow dividers (flow bounds, imaginary walls, bankful points) defined in profiles. Meshing-Profiles will not be adjusted by up- and downstream profiles of section to be meshed, but based on perpendicularity to given river axis.
• Alow to specify element lengths absolute or based on widht-length ratio
• River axis can be taken from belonging cross section data set or from any imported shape file

• cross section management in 1d2d now supports almost all features available in WSPM (including direct access to cross section database)
• cross section management is now structured similar to WSPM model (i.e. water bodies and reaches are now modelled as well) including management of a river axis
• Adapt visualization scaling of profiles in cross section view; width:
  • show available width
  • devided
  • bankful point
  • flow area
  • center on lowest point (including width specification)
• height:
  • show available height
  • adjust to lowest point (including height specification)

When scrolling through profiles these settings remain which eases the visual comparability of profiles from one to the other.

• Added cross section management tool to straighten and orthogonalize profiles based on given river axis geometry. This helps generating smooth river channel meshes.
• Adjust width coordinates to deepest points of profiles, so that deepest point will get width = 0.0m, left negative, right positive.

• Reading / Writing DFlow FM netCDF files including mesh with / without results
• Export cross section profiles including buildings in DFlow-FM format (prepare buildings)
• Export roughness polygons in xyz format
• elevation models may be exported in the xyz format
