Summary: We introduce a stable numerical space marching scheme based on discrete mollification – implemented as an automatic adaptive filter – for the approximate identification of temperature, temperature gradient, and source terms in the two-dimensional inverse heat conduction problem (IHCP). The stability and error analysis of the algorithm, together with some numerical examples, are provided.
