Electromagnetics Settings and Convergence Criteria

Convergence refers to the point at which further iterations are no longer necessary. An important part of determining whether your solution is appropriate is to judge whether the solution has converged to an acceptable level.

By default, Discovery will automatically use a set of numerical convergence settings that are suitable in most cases. You can explicitly set the convergence criteria by going to Simulation Options in the ribbon of the Simulation tab and make modifications under Electromagnetics Options. This option only affects solutions when in the Refine stage.

• Modify frequency points to specify the Far-field, Near-field and S-parameters frequency points.
• Specify loss settings:
  • determine whether Dieletric losses should be based on materials or if they can be ignored.
  • specify the Perfect conductivity threshold value to set the material threshold for electrical conductivity.
• Specify convergence settings:
  • specify the Maximum simulation duration for each simulation. The simulation is considered converged once the volume-integrated electric field intensity drops below a ratio of its peak value.
  • enter the Target numerical convergence to specify this threshold. The simulation will run longer for smaller values.
