nodal mass output

Hi,

I was wondering if there is a way of outputting nodal mass in opensees. I'm using PressureDependMultiYield with quadUP element. Unit density (rho) of the material is provided in the former so I believe nodal mass is computed internally during gravity analysis prior to earthquake analysis.

Also if I provide mass (via -mass command), is this mass automatically added to that already computed internally?

Thanks!

Hi,
I add some codes and now I can get mass,init , tang , damping matrices of analytical model if these help you I can Upload my Opensees Here !
