CALFEM is Lund University's set of MATLAB programs for finite element method education. This work describes two new time-stepping functions for computing transient response based on an implicit Runge-Kutta method that provides better accuracy and stability than the methods currently implemented in CALFEM version 3.2. The codes described in this report are available by ftp.
