Post processing of COQUE-3D calcalation
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
