Hi,
There are two way to do that:
1.Explicitly build FE model (with elements and joints - expl. mesh) and manually assign joint masses (calculated in advance) along each degree of freedom. This way is not practical for large models, but is suitable for comparative study.
2. More practical and fast is to use automatic mesh options for elements and program options to define mass sources:
* Firstly - Assign/ Frame (or Area)/ Automatic Frame/Line/ Automatic Frame Subdivide... . Preview and check mesh (model).
* Define /Static Load cases - one case with self weight included (with self weight multiplier or explicitly assigned as load) - e.g. LSw1
*Define/Mass Source/... From loads - define "Mass Combination" - define mass multiplier for loads - e.g. Lsw1 with multipl. =0.2.
Other two options are also possible - they are connected with mass properties - material mass and additional line and area masses.
Always check after analysis calculated masses. Above proposed way of assigning mass from loads suffer from missing info for mass in advance ( before analysis).
Regards
