MAGNETIC FIELD SIMULATION PROGRAM, INFORMATION PROCESSING DEVICE, AND MAGNETIC FIELD SIMULATION METHOD

摘要

To detect an inaccurate simulation result when shortening the calculation time of a micromagnetic simulation.SOLUTION: An information processing device 1 approximates the magnetostatic field vector of each element for each time of day using magnetization vector data when simulating the state of magnetization vector of each element that is obtained by dividing a magnetic substance into meshes. The information processing device 1 calculates, for each element, magnetization vector data at the next time of day using magnetostatic field vector data at a specific time of day. The information processing device 1 calculates, for each element, a change amount of magnetization vector data between the specific time of day and the next time of day. The information processing device 1 discontinues a simulation on the basis of the change amount of respective magnetization vector data having been calculated for each element, and outputs to the effect that the simulation has been discontinued.SELECTED DRAWING: Figure 1
