We have made a series of hydrodynamic calculations of core collapsing models to examine the effects of temperature dependence of nuclear compressibility. With this aim we have focused on the influence of the equation of state derived by Viñas et al. for two extreme types of nuclear interactions. A Multigroup Trapping Scheme for neutrino transport is used. Results show that we can reach a maximum central density in the range to 1.5ρ0 to 2.5ρ0, depending on the particular force used.
