The determination of a proper time step for transient analysis using CINDA, SINDA or MITAS can be a serious problem. Too large a time step can cause serious errors; too small a time step can be expensive for large thermal networks. There was no simple method to determine proper time steps and the resulting accuracy prior to the development of the subroutine FBECHK by J. T. Skladany and F. A. Costello. This paper describes a new method incorporating the theory of FBECHK into a new execution routine that is more efficient and can accurately consider discrete changes in heating due to such events as solar eclipses and thermostatic switching of heaters.
