Abstract: Calculation of electric field was one of important parts in numerical simulation of arcjet flow field.The efficiency of the calculation of the whole flow field is to most extent depending on the efficiency of this calculation and then it was necessary to take some steps to improve it.The effects of using multigrid method on efficiency improvement of electric field calculation were studied after establishing numerical model and based method on this calculation,and its special effects were verified by numerical experiments.
