7.18.1.1. Line Commands

Add Nonlinear Control

Syntax: Add Nonlinear Control Control_name [ Control_parameters… ]

Parameter	Value	Default
Control_name	string	–

Add Utility

Syntax: Add Utility Utility_name [ Utility_parameters… ]
Summary: Add the named utility to the nonlinear solver which executes at the specified time. Utility parameters can be supplied in the form of key=value pairs.

Parameter	Value	Default
Utility_name	string	–

Advection Velocity For

Syntax: Advection Velocity For EquationName {=} AdvectionVelocityModel [ Parameters… ]
Summary: Causes the specified equation to use the specified advection velocity. If this command is not given, the standard advection velocity is used: fluid velocity minus the mesh velocity.

Parameter	Value	Default
EquationName	string	–
{=}	{= \| are \| is}	–
AdvectionVelocityModel	string	–

Anneal Mesh On Startup

Syntax: Anneal Mesh On Startup
Summary: With the command in the Region block Aria will search for a displacements field and, if found, will apply the displacements to the model and physical coordinates.

Axisymmetry Axis

Syntax: Axisymmetry Axis {=} {x | y}
Summary: When the COORDINATE SYSTEM = AXISYMMETRIC command appears within the Finite Element Model command block one can select at the Region level the coordinate axis about which the 2D axisymmetric sweep will occur. Note that there can be no overlap between the model and the axis of rotation.

Combine Rebalance Groups

Syntax: Combine Rebalance Groups {=} CombinedRebalanceGroups…
Summary: Specifies a list of rebalance groups to combine into the DEFAULT rebalance group for the equation system. By default, each equation system will be split into the following four rebalance groups: DEFAULT, ASSEMBLY, LINEAR_SOLVE, and CHEMEQ_UTIL. Only the ASSEMBLY and CHEMEQ_UTIL rebalance groups can be combined into the DEFAULT rebalance group. The LINEAR_SOLVE rebalance group uses a non-time based measure of the work load and so can not be combined into the DEFAULT rebalance group. Note that combining rebalance groups may hide load imbalances in the equation system.

Parameter	Value	Default
{=}	{= \| are \| is}	–
CombinedRebalanceGroups	string…	–

Constrain Dof

Syntax: Constrain Dof DofName On {cdfem_edge_nodes | cdfem_internal_nodes | cdfem_parent_nodes} [ On SurfaceName ]

Display Truncation Error For

Syntax

Display Truncation Error For Solution_dof [ With HowMany Entries ]

Summary

Provides ability to request log file output of the maximum computed truncation error values.

Description

This command allows one to request the maximum magnitudes of predictor error at a small number of DOF to the log file. For vector Fields only the magnitude over all components is considered. Note that additional log file output can be IO intensive so use of this command line should be restricted to debugging of a model.

Default is 5 values.

Enable Rebalance

Syntax

Enable Rebalance [ With Threshold {=} Threshold ]

Summary

Activate rebalance, optionally specifying the rebalance threshold.

Threshold is in terms of the ratio of the maximum (over all processors) cpu time per timestep divided by the average cpu time per timestep. If the observed value of this ratio meets or exceeds the given value, rebalance will be performed.

The default threshold value is 1.25.

Syntax

Predictor Fields

Syntax

Predictor Fields {=} Field_names…

Summary

Specification of active fields to be used in predictor algorithm.

Description

Specifies which fields to examine or ignore in the algorithm for adaptive time step selection. Fields that are not predictor fields will not be predicted solutions for the first two time steps. This is important for fields like pressure and electrostatic potential which may exhibit large jumps in their solutions between the initial conditions and the first solutions owing to the absence of time dependent terms in their governing equations during startup.

The selected fields will contribute to the $d_{n+1}$ norm discussed in the TIME TRUNCATION ERROR time block command. This command line can be provided multiple times with cumulative results.

By default all fields are included. All field names following the optional “NOT” keyword will be excluded from the selection algorithm.

Segregated Global Nonlinear Initial Residual Tolerance

Syntax: Segregated Global Nonlinear Initial Residual Tolerance {=} Pt
Summary: Convergence tolerance for global segregated nonlinear residual for the iteration. The iteration is considered finished when all of the individual equation systems have an initial nonlinear residual less than the given tolerance. This is cheaper than other tests that require recomputing the nonlinear residual. However, care should be taken since the initial nonlinear residual of the individual equation systems might not be a good measure of the final nonlinear residual of those systems due to deltas produced by other equation systems.

Segregated Global Nonlinear Target Number Of Steps Per Time Step

Syntax: Segregated Global Nonlinear Target Number Of Steps Per Time Step {=} target_iterations
