Electrostatic Solver Settings

For an electrostatic solution you can do the following:

• For 3D designs, you can Enable an Iterative Solver
• Import Mesh
• For 2D designs, the Thermal Two-Way Coupling\Relaxation setting can be used to improve two-way coupling convergence by applying the relaxation factor to the temperature field. When the thermal modifier takes on a nonlinear form, the convergence of the solution field in Maxwell's equations may fail during two-way coupling iterations. With nonlinear iterations, using an under-relaxation factor can mitigate the risk of overshooting in the property updating process.

The range of the relaxation factor is from 0 to 1. In general, a smaller relaxation value helps convergence, but may increase the total number of iterations. The default relaxation factor is 1.0.

The Thermal Two-Way Coupling\Relaxation setting is applicable only when Enable Feedback is checked in Temperature of Objects window, which invokes two-way coupling instead of one-way coupling. The relaxation setting is

• applicable to all Maxwell 2D designs,
• applicable to both geometry modes (Cartesian XY and Cylindrical about Z),
• does not support non-intrinsic and intrinsic variables.

If activated in the Solve Setup window, the Relaxation Factor is also available in the Solve Properties window:
