Modal analysis - steps

[Anonymous]

for RSAPRO 2012

When I run only a modal analysis, in the Modal Analysis Parameters window the Disregard density must be checked?

What recommandations are for Mass matrix and Method then?

Based on your answers to previous questions, if I choose to perform a seismic analysis, can you detail the necessary steps?

Can you explain what is in the picture regarding Lanczos method?

I read some answers on forum but I need an overview from more experienced colleagues.
