8. F modeling#
8.1. Characteristics of modeling#
The two straight parts of the pipe are meshed with TUYAUcoudés elements, based on 3-knot meshes. The elbow is meshed with HEXA20 volume meshes.
This modeling therefore makes it possible to validate the good transmission of the ovalization (mode 2) between the elements TUYAU on the right parts and the elbow in 3D, and validates the 3D_ TUYAU connection.
8.2. Characteristics of the mesh#
234 SEG3 stitches.
512 HEXA20 stitches.
8.3. Tested values#
