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.
