Embodiment 1
[0079] A prediction method in time-domain electromagnetic field numerical calculation, the time-domain electromagnetic field numerical calculation adopts explicit iteration on time, the iteration time step is limited by the Courant-Friedrichs-Lewy condition, in the previous time step, only the position to be sought and the position to be sought Finding the electromagnetic field value at the adjacent position of the position will have an impact on the position to be sought at the current time step, and it is characterized in that:
[0080] The electromagnetic field value of the position to be requested in the current time step is predicted by the electromagnetic field value of the position to be requested in the previous time step and the adjacent positions of the position to be requested.
[0081] The numerical calculation of the electromagnetic field in the time domain includes but is not limited to numerical calculation methods such as FDTD and DGTD, which are not specificall...
Embodiment 2
[0089] see figure 1 , this embodiment provides an explicit iterative time-domain limited electromagnetic field calculation method limited by the Courant-Friedrichs-Lewy stability condition, including:
[0090] 101 Comparing the electromagnetic field value of each position to be requested in the previous time step with the judgment condition, if the judgment condition is satisfied, the position belongs to area 2, otherwise it belongs to area 1;
[0091] 102 traverse all the positions in the existing area 1, and let all their adjacent positions also belong to the area 1;
[0092] 103 adopt Algorithm 1 for all positions in Area 1, and use Algorithm 2 for all positions in Area 2;
[0093] said location is a grid cell or a grid edge or a grid node;
