Post processing of COQUE-3D calcalation

[under construction]

In this contribution the main (and only) focus is on the postprocessing of the displacements and stresses of shell COQUE-3D elements. The centre nodes of tria7 and quad9 elements used for the discription of the displacements field of COQUE_3D poses some nasty problems in the postprocessing with Salome. To overcome this problem the results are projected on the original quadratic mesh without the centre node.

• preproccesing:
• definition of geometry in Salome
• partitioning of the geometry and groups
• meshing of the geometry
• definition of the groups
• (maybe: python script which makes editing much easier ...)

• static analysis with pressure or force applied on a group or nodes

• postprocessing:
• viewing displacement in Salome
• determination of stresses, see also tables

• interface ASTK
