The commonly used transmission‐line modelling (TLM) network of one‐dimensional diffusion problems often results in unwanted oscillations. Two different TLM configurations (line boundary (LB) and resistance boundary (RB)), are investigated with some techniques necessary to reduce the oscillations. Comparisons between the various LB and RB models addressed in this paper, indicate that, in general, two‐dimensional TLM models produce consistently more accurate results.
