6. D modeling#

6.1. Characteristics of modeling#

Hexahedral elements are used to mesh the cylinder in 3D.

The interface model between solid and fluid has the following characteristics:

  • Modeling: “3D”, Phenomenon: “Thermal”

  • Modeling: “3D”, Phenomenon: “Mechanics”

  • Modeling: “FLUI_STRU”, Phenomenon: “Mechanics”

6.2. Tested sizes and results#

The results are tested with the three types of interfaces by considering a field of type CHAM_NO on the skin of the 3D mesh.
