Why does my AXIEM simulation take so long, and how do experienced users speed it up?

AXIEM simulation time is mainly affected by mesh size, geometry complexity, frequency range, and solver selection. Even a small layout change can significantly increase the number of mesh cells, resulting in much longer simulation times.

To improve simulation speed without sacrificing accuracy:

• Use Advanced Frequency Sweep (AFS) instead of simulating many discrete frequency points.
• Simplify non-critical geometry where possible.
• Avoid unnecessarily fine mesh settings.
• Check the generated mesh to identify regions driving excessive cell counts.
• Start with a simplified model and add detail only where it impacts performance.

Solver selection also plays an important role:

• Direct Solvers are ideal for smaller problems but do not scale well as the structure grows.
• Iterative Solvers (fast solvers) are better suited for larger designs and generally offer better memory usage and simulation performance.

Recommendation: Use Auto Configure in the EM Options dialog. AXIEM will automatically choose the optimal solver based on problem size and frequency, providing the best balance between accuracy and simulation speed.
