5. C modeling#

5.1. Characteristics of modeling#

Q4 elements are used to mesh the surface of the cylinder.

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

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

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

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

5.2. Tested sizes and results#

The results are tested with the three types of interfaces by considering a field of type MODE_MECA.
