查询词典 sparse

is applied to construct the three-dimension model for finite element analysis. Short circuit and open circuit of the field winding and the teeth and slots structure of the rotor are discussed. An appropriate three-dimensional mesh is made. The corner point problem of conductor is eliminated. Furthermore, a new memory structure for sparse complex matrix and a PCCG method based on it are introduced to save memory and computation time.
