In the paper the freezing process of biological tissue subjected to the action of two internal spherical cryoprobes is discussed. The problem is strongly non-linear because the parameters appearing in the mathematical model of the process are temperature-dependent. In order to solve the task considered, the finite element method for 3D domain oriented in the Cartesian coordinate systems has been used. In the final part of the paper the example of computations is shown.
