The properties of the object for 6 D.O.F solver has to be specified explicitly with a UDF and not in the materials panel. Use the macro DEFINE_SDOF_PROPERTIES to define mass and moment of inertia. The properties that are specified in the materials panel are limited to flow calculations. In solids, it may be used to calculate the heat transfer.<\/p>\n","protected":false},"template":"","class_list":["post-161730","topic","type-topic","status-publish","hentry","topic-tag-4424","topic-tag-dynamic-meshing-udf","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-moving-deforming-mesh","topic-tag-other"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
