dear seismosoft
as a new user of seismostruct ( and an old user of seismosignal ) , i stumbled upon a rather simple question . is there any way to obtain stiffness and mass matrices for a given modeled structure from seismostruct ?

The mass matrix diagonal ([M] is a diagonal matrix) is output in eigenvalue analysis, Nodal/Mass Quantities>Nodal Masses. The stiffness matrix is constantly updated during the analysis, and is not output.
