Subgridding method for speeding up FD-TLM circuit simulation
نویسندگان
چکیده
This paper describes a new subgridding approach with a view to improving the efficiency of full-wave simulation of electronic circuits. The proposed subgridding method has been incorporated into a full-wave variable-mesh finite-difference transmission line matrix (FD-TLM) simulator. By incorporating the proposed subgridding method, a speed-up of about 2 has been attained. The computational acceleration is measured by comparing the run time of subgridding method with the run time of the FD-TLM method without any subgridding.
