Improving Convergence by Solving “Without Circuits”
- Issue with Convergence:
- Complex current distribution in inductors or transformers can lead to non-convergence in solving for inductance, especially at higher frequencies.
- Introduction of “Without Circuits” Option:
- This option helps the solver tackle difficult convergence problems.
- By selecting “Without Circuits,” the solver ignores circuits and only applies voltage on external terminals.
- Solving Process:
- The solver simplifies the problem by focusing on voltage excitation only, eliminating the complexity of current distribution.
- Parametric sweeps for voltage or frequency can still be conducted for analysis.
- Results:
- Results obtained using the “Without Circuits” option will appear similar to those obtained with circuits.
- Inductance values can be calculated using circuit and energy methods as usual.
- Benefits:
- Speeds up simulations and aids in faster convergence of solutions.
- Limitations:
- The “Without Circuits” option does not allow for solving with current excitation.
- This option is only available for full domains and inductance calculations.
