The paper presents a combined fine–coarse mesh TLM method. This technique reduces the memory storage and the computational time when modelling complex structures. In the combined fine–coarse mesh model, the region of interest is covered with a set of transmission‐line fine meshes. The remaining part is covered with regular (or irregular) coarse meshes. The fine‐mesh nodes are connected through busbars to the adjacent coarse‐mesh nodes. The combined fine–coarse mesh TLM technique is applied to some diffusion problems. Significant savings in computational time and memory storage are obtained without loss of accuracy.
