This paper examines the accuracy of a space marching formulation for solving two-dimensional inverse heat conduction problems. The parameters that have a major influence on the solution such as time step size, measurement errors and Biot number are investigated. The temperature and heat flux on the surface of a body are estimated on the base of the temperature measurement at a number of sensors located inside the body. The initial condition is assumed to be unknown. The solution is presented in terms of temperature data and their derivatives with respect to time.
