Modal Analysis of a beam | The Best Modal Analysis Tutorial | ANSYS APDL

When you declare the density p=7830 kg/m^3 (MAT -> DENS) AND declare the additional mass per unit length 15 kg/m (Sections -> Beam -> Sect Control), the total mass of the entire model will be M = m_1 + m_2, where: m_1 = 7830 x Volume_shaft m_2 = 15 x L So, the result will be more accurate? Is that correct?

Thank you for the great video, where did you define or input the mass of the shaft : 15 kg/m ?

Sections -> Sect Control It is missing in this example. If you set it, the result matches
