Reply to Comment on 'Electro-thermal device and circuit simulation with thermal nonlinearity due to temperature dependent diffusivity'

For original paper see ibid., vol. 36, no. 23, p. 1966-8 (2000). The comments made by Krabbenhoft and Damkilde [for comment see ibid., vol. 37, no. 24, p. 1481-2 (2001)] help clarify the approximation involved in the thermal impedance matrix implementation of the time variable transformation.
