Stationary Current Solver Specials

Simulation: SolverStart SimulationSpecials

Solver type

Drop down list to specify the solver type used to solve linear systems of equations. Available options are

Auto: The solver type is automatically set depending on the problem size (recommended)

Iterative: An iterative solver is used.

Direct: A direct solver is used.

Solver order

This option allows to specify whether the stationary current solver with tetrahedral mesh uses first-, second- or third-order accuracy. Second-order is the default due to its good compromise between accuracy and memory efficiency. However, if the structure is geometrically complex and therefore comes along with huge memory requirements, first-order is an alternative. On the other hand, third-order delivers a better solution for coarsely discretized problems.

Curvature...

This button opens the Special Mesh Properties dialog, where the curved element order can be specified.

Maximum iterations

The number of iterations performed by the linear solver is automatically limited by a number depending on the desired solver accuracy. If you would like to prescribe a fixed upper limit for number of linear iterations, deactivate the "Automatic" checkbox and enter a positive number in the edit field

Nonlinear accuracy

Select here the desired accuracy for the nonlinear calculation cycle.

PECs without sources

Grounded: All PEC domains to which no source is assigned and electric boundary conditions are considered like fixed potentials with value 0. (default)

Floating: All PEC domains to which no source is assigned and electric boundary conditions are considered like floating potentials.

Ok

Accepts the changes and closes the dialog.

Cancel

Closes this dialog box without performing any further action.
