In the paper the parametric inverse problem [1, 2] concerning the identification of latent heat is considered. This parameter appears in the energy equation in the source term if the one domain approach is taken into account [4]. The identification of latent heat is possible under the condition that one disposes the additional information concerning the temperature field in the casting domain (cooling curves at the selected set of points). In order to solve the problem the algorithm using the sensitivity coefficients and least squares criterion has been used. The numerical example is presented in the final part of the paper.
