Abstract
In the original effective heat capacity method the latent heat effect is approximated by a large effective heat capacity over a small temperature range. This method is simple in concept and easy to implement. However, it is so sensitive to the choice of the phase change temperature interval and the chosen time integration scheme that non‐convergence always occurs when it is implemented with implicit time integration schemes. Presents the cause and cure of non‐convergence in effective heat capacity methods and discusses sample results.
