In order to enhance stability of the implicit scheme for the initial stress rate method, a nonlinear source term is usually approximated by a linear function with a negative gradient. This analytical procedure is not always possible for a complicated problem such as a solidification simulation. Here, a numerical procedure for linearization is proposed which is theoretically based on the penalty method. A fastening of degrees of freedom and solidification simulation by the temperature recovering method are demonstrated to show the appropriateness of the proposed method.
