Until 17.1 Fluent Version, to add an External Force with the SDOF Model, the function prop[SDOF_LOAD_F_X] is used in the DEFINE_SDOF_PROPERTIES Macro. See attached a UDF which apply a Spring Force. From Fluent 17.2, the same kind of UDF can be used, but the Spring Force can be defined in the new Six DOF Properties panel directly too. See the 17.2 Fluent User\u2019s Guide for more details (User’s Guide > Modeling Flows Using Sliding and Dynamic Meshes > Using Dynamic Meshes > Six DOF Solver Settings).<\/p>\n
