Description
Base properties for implicit solvers.
Such integrators require solution of a nonlinear problem, typically solved using an iterative process, up to a desired tolerance. At each iteration, a linear system must be solved.

inlinevirtual |
Method to allow de-serialization of transient data from archives.
Reimplemented in chrono::ChTimestepperEulerImplicit, chrono::ChTimestepperHHT, chrono::ChTimestepperNewmark, chrono::ChTimestepperTrapezoidal, chrono::ChTimestepperTrapezoidalLinearized2, and chrono::ChTimestepperTrapezoidalLinearized.
◆ ArchiveOut()
|
inlinevirtual |
Method to allow serialization of transient data to archives.
Reimplemented in chrono::ChTimestepperEulerImplicit, chrono::ChTimestepperHHT, chrono::ChTimestepperNewmark, chrono::ChTimestepperTrapezoidal, chrono::ChTimestepperTrapezoidalLinearized2, and chrono::ChTimestepperTrapezoidalLinearized.
◆ SetAbsTolerances() [1/2]
|
inline |
Set the absolute tolerances.
These tolerances are optionally used by derived classes in the Newton-Raphson convergence test. This version sets equal absolute tolerances for states and Lagrange multipliers.
◆ SetAbsTolerances() [2/2]
|
inline |
Set the absolute tolerances.
These tolerances are optionally used by derived classes in the Newton-Raphson convergence test. This version sets separate absolute tolerances for states and Lagrange multipliers.
◆ SetRelTolerance()
|
inline |
Set the relative tolerance.
This tolerance is optionally used by derived classes in the Newton-Raphson convergence test.
