Nonlinear Iterative Solver

This is a function that allows you to shorten calculation time when using a nonlinear material in a transient response analysis. When using this feature, we have seen approximately a threefold improvement in analysis speed compared to when it is not used.
This function is not recommended for either an analysis involving motion where the displacement per step is large, or for an analysis that does not use a current source in the circuit or the current condition. The procedure is as follows:

  1. Display [Nonlinear Calculation] under [Study Properties].
  2. Click the [Use High Speed Solver] check box.

Parallel Solver Updated

The parallel solver SMP (parallel calculation using multi-cores in a computer) from JMAG improves the productivity of analysis work in the design process.
With 36 paralell processes in SMP, the calculation time of approximately 1/10th the time for non-parallel analysis can be achieved.

High Parallel Solver

Higher electromagnetic field analysis using a high parallel solver.
With a model size of approximately 1,000,000 elements, 37 times the speed increase is achieved at 128 parallel processes.
