ReferenceResidualProblem
Problem that checks for convergence relative to a user-supplied reference quantity rather than the initial residual
Description
By default, MOOSE checks convergence using relative and absolute criteria. Once the residual drops below either an absolute tolerance, or the residual divided by the initial residual for the current time step drops below a relative tolerance, the solution is considered converged. This works well for many problems, but there are some scenarios that are problematic for convergence:
There is a large scaling difference between the solution variables, so taking the norm of the combined vector skews the convergence check so that it becomes increasingly dominated by the variable with larger absolute values in the residual vector as the scaling difference increases.
The model conditions have changed very little from the previous step, so the initial residual is very low because the solution is essentially converged before any nonlinear iterations have been performed. The standard convergence check that uses the initial residual as a reference quantity eventually fails after a few steps because the solution is forced to converge to tighter limits with each time step, until numerical roundoff error prevents the solution from converging more tightly.
The state of the problem is such that the values of the residual at all degrees of freedom where Dirichlet boundary conditions are applied are zero in the converged solution. An example of this is a mechanics model that has Dirichlet boundary conditions to prevent rigid body motion, but the model only experiences free thermal expansion, so there are no reaction loads at those points. Another example is if there is a time step when no loading is applied.
ReferenceResidualProblem
checks for convergence by comparing the residual to a different reference quantity (instead of the initial residual). The user specifies a reference vector that can be used in a relative convergence check. Because the solution variables can have significantly different scaling, the convergence check performed in ReferenceResidualProblem
checks convergence of the solution variables individually. When the norm of the residual for each solution variable is less than either the relative tolerance times the norm of the corresponding reference variable or the absolute tolerance, the solution is considered converged.
By checking the convergence of individual variables and comparing to reference quantities that are meaningful even when the solution is not changing, ReferenceResidualProblem
addresses the first two issues listed above. The third issue is potentially more of a problem with ReferenceResidualProblem
than the standard MOOSE convergence check, and dealing with it is discussed in Dealing with Residuals that are Zero at Boundaries.
Use of this procedure requires that the user provide physically meaningful reference quantities. The vector of the reaction loads (in the case of mechanics) or integrated fluxes (in the case of diffusion problems) is typically suitable for this purpose, as it provides a measure of the loading applied to the system. To make these reference quantities, simply add the extra_vector_tags = <reference_vector_name>
param/value pair to the computing objects that you want to add into the reference vector. An explicit example is given in Example Input Syntax below.
Since relative convergence is computed differently with this approach, the nonlinear relative tolerance required to achieve the same error is typically different than with the default approach in MOOSE, and the differences will vary by the problem. The code user must evaluate the behavior of their model to ensure that appropriate tolerances are being used.
Dealing with Residuals that are Zero at Boundaries
As mentioned in the third case above where relative convergence checks can fail, the converged solutions for some problems are zero on all boundaries with Dirichlet boundary condition (BC) because of the nature of the loading conditions. This would make the ReferenceResidualProblem
convergence checks fail because the norm of the reference vector would be zero in this case. This is manifested when the reference values decrease at the same rate as the residuals, so relative convergence is never achieved.
In some mechanics problems, such as those with symmetry planes, this might happen only in one direction. This situation can be remedied by grouping together the residuals for all components of the displacement variables rather than checking them individually. If the reference vector for one of the variables in the group is zero (because there are no Dirichlet BCs that restrict the solution in that direction), but it is nonzero for the others, the residual for the set of variables will be checked together, and the variable with a zero value will not prevent convergence as it normally would. Grouping variables is accomplished by using the group_variables
option, which is used to provide one or more lists of names of variables to group together.
In some cases, however, there may be no degrees of freedom with nonzero residuals at Dirichlet BCs for even a group of variables. This could happen in mechanics problems that only have free expansion, in which the Dirichlet BCs are important for preventing rigid body motion, but do not restrain the deformation of the body. This could also happen if there is simply no loading on a model during a time step.
It is necessary in such cases to also specify an absolute tolerance using nl_abs_tol
, which is a problem-specific value that must be higher than the residual below which the solution can no longer converge tighter due to numeric roundoff errors, but sufficiently low to ensure that the solution is converged when that limit is reached.
Example Input Syntax
[Problem]
type = ReferenceResidualProblem
extra_tag_vectors = 'ref'
reference_vector = 'ref'
[]
(test/tests/problems/reference_residual_problem/reference_residual.i)where the extra_tag_vectors
parameter indicates the additional vectors that should be added to the nonlinear system. This parameter must contain the name of the vector to be used for the reference_vector
. In this example we only create one extra vector, the ref
vector, that will be used for holding the reference residuals. To have computing objects add into the reference vector, simply add the extra_vector_tags = <reference_vector_name>
param/value pair as illustrated below:
[BCs]
[u]
type = RobinBC
boundary = 'left right'
coef = ${coef}
variable = u
extra_vector_tags = 'ref'
[]
[v]
type = RobinBC
boundary = 'left right'
coef = 1
variable = v
extra_vector_tags = 'ref'
[]
[]
(test/tests/problems/reference_residual_problem/reference_residual.i)In this example we are using the integrated fluxes as the reference quantities that we will compare the individual variable residuals to.
Grouping Variables
[Problem]
type = ReferenceResidualProblem
extra_tag_vectors = 'ref'
reference_vector = 'ref'
group_variables = 'disp_x disp_y;
scalar_strain_zz1 scalar_strain_zz2'
[]
(modules/combined/test/tests/reference_residual/group_variables.i)Multiple groupings of variables can be provided in group_variables
by separating them by semicolon. Convergence for those variables that are not given in group_variables
is checked individually. A given variable can only be included in one group.
