A finite element mesh needs to be scaled. For example, the mesh has been imported assuming the wrong units system (say 'N/mm/tonnes' instead of 'N/m/kg').
Within the context of the '.fem' file, use the 'Node Translate' command available from the 'Nodes and Elements' ribbon bar with the following options in order to scale the mesh:
Type = Translate
Translation Method = Scale Model
Note that different scaling factors can be used for the X, Y and Z directions, where the X, Y and Z vector directions are defined with respect to a chosen reference coordinate system.
Also note that while this command can be used to scale the size of the mesh, any associated material property data, physical property data or applied loads will be un-altered and, if necessary, must be modified separately.
