HFSS Setup: DC RTab

Select the DC R (i.e., DC Resistance) tab of the HFSS Setup window to access the following settings.

Conduction Adaptive Solution

• Maximum Number of Passes – the maximum number of mesh refinement cycles to perform. This value is a stopping criterion for the adaptive solution; if the maximum number of passes has been completed, the adaptive analysis stops. If the maximum number of passes has not been completed, the adaptive analysis continues unless convergence criteria are reached.
  Important:

  The size of the finite element mesh and the amount of memory required to generate a solution increases with each adaptive refinement of the mesh. Setting the maximum number of passes too high can result in the simulation requesting more memory than is available or taking excessive time to compute solutions.

• Minimum Number of Passes – the minimum number of mesh refinement cycles. The simulation will not stop analysis until after this number of passes has been completed.
• Minimum Converged Passes – the minimum number of passes that must meet convergence criteria before the adaptive analysis will stop.
• Percent Error – the desired solution accuracy. Smaller values produce more accurate but slower solutions; larger values produce less accurate but faster solutions.
• Percent Refinement Per Pass – determines how many tetrahedra (or prism) elements are added at each iteration of the adaptive refinement process. The elements with the highest error are refined. The default value is 30%.
