SolutionΒΆ
Where a field contains all basic information of one variable, the solution contains the
basis function weights (alpha) and value for an individual solution type.
Here the type property defines which solution is represented. The
type is user-defined (it is set in the settings file), and possible
values are
type |
description |
|---|---|
exact |
exact solution |
last |
most recent solution (solution at time level \(n\)) |
last-1 |
solution at time level \(n-1\) |
last-2 |
solution at time level \(n-2\) |
nonlinear |
backup of last solution (used to check for nonlinear convergence) |
coupling |
backup of last solution (used to check for coupling convergence) |
error |
difference between last and exact solution |
residual |
residual of the least-squares system (\(r = b - A x\)) |
Note
The error solution is computed automatically if there is an exact solution as well.
