Hi， openseespy team.
I would like to know if there is a command in openseespy to obtain the initial stiffness and mass matrices of arbitrary or commonly used elements? I checked openseespydoc, and it seems that currently only the basic stiffness matrix of beam-column elements is provided. How to obtain it for multi-node elements such as shell elements? Many thanks！
