How can I display nodal masses?

Answer

For members (RSTAB) or members, surfaces, and solids (RFEM), you can display the material weight W. Simply select the entire structure or a part thereof and right-click to open the shortcut menu. Here you will find the entry "Center of Gravity and Info ...".



However, the nodal masses are not apparent from this.

To generate nodal masses, you can use the RF-/DYNAM Pro Natural Vibrations add-on module. In this case, you it is possible to create a natural vibration case where the mass acts e.g. only in the Z direction. After having calculated the natural mode case, the "nodal masses" are available in the results tables of RF-/DYNAM Pro.


In RF-/DYNAM Pro, you can optionally convert the nodal loads into masses by applying the force components of the respective load case to the natural case calculation.
