Lot 4.1.B - spatially displaying mesh quality

TRGRID and Janet can show spatially where the mesh might have to be changed. This feature is to show similar colour fields. \

As a minimum, the feature developed within the SALOME-QGIS plugin will include the generation of spatial fields / colouring for the following node / edge / triangle properties :
node connectivity

• the number of neighbouring nodes, displayed at every nodes (highlighting as a coloured squares at the node) toggling between values ..
  • number of interior node with strictly less than 5 neighbours (bright pink)
  • number of node whose number of neighbours is 5, 6 or 7 - quality nodes (light green)
  • number of node with exactly 8 neighbours (orange)
  • number of node with exactly 9 neighbours or more (red)
• highlights orphan nodes (blue)
• highlights nodes between disjoint triangles
• highlights orphan elements (colouring the triangles)
• the number of clockwise and counter-clockwise elements
• over-constrained triangles\

mesures

• display of coloured angles, more than 70 dgrees (blue) and more than 90 degrees (purple), and less than 50 degrees (orange), and less than 30 degrees (red)
