Holds basic parameters that affect solver convergence.

Attributes

Attribute	Summary
timescale_control	‘Timescale Control’ parameter.
timescale_factor	The estimated auto timescale is multiplied by this number.
local_timescale_factor	‘Local Timescale Factor’ parameter.
physical_timescale	‘Physical Timescale’ parameter.
maximum_number_of_iterations	‘Maximum Number of Iterations’ parameter.
maximum_number_of_coefficient_loops	‘Maximum Number of Coefficient Loops’ parameter.
minimum_number_of_coefficient_loops	‘Minimum Number of Coefficient Loops’ parameter.
minimum_number_of_iterations	‘Minimum Number of Iterations’ parameter.
length_scale_option	Option for calculating Auto Timestep length scale. Conservative uses the cube root of the fluid volume, and Aggressive uses the maximum extent of the fluid volume.
length_scale	Specified length scale for Auto Timestep.
solid_timescale_control	‘Solid Timescale Control’ parameter.
solid_timescale	‘Solid Timescale’ parameter.
number_of_dependent_variable_updates	Maximum number of dependent variable updates in a time step.
maximum_timescale	‘Maximum Timescale’ parameter.
timescale_ramping_factor	‘Timescale Ramping Factor’ parameter.
number_of_timescale_updates	‘Number of Timescale Updates’ parameter.
residual_relaxation_iterations	Number of iteration to relax residuals.
solid_timescale_factor	For solids, the auto timescale is equal to the estimated timescale times this factor.
stabilisation_control	Determines what action to take if a time step fails.
