Solid Temperature Solver¶

The SolidTemperatureSolver configures the linear and nonlinear solution strategy of the SolidTemperatureModel. For the underlying method, see Linear Solvers and Newton Form.

Access it with SolidTemperatureModel.get_solver().

solver: mufem.thermal.SolidTemperatureSolver = model.get_solver()

Methods¶

set_verbose¶

solver.set_verbose(verbose: bool)

Enable or disable verbose solver output.

Args:

• verbose: If True, the solver prints additional information.

set_iteration_number¶

solver.set_iteration_number(iteration_number: int)

Set the maximum number of iterations of the linear solver.

set_relative_tolerance¶

solver.set_relative_tolerance(relative_tolerance: float)

Set the relative tolerance of the linear solver.

set_absolute_tolerance¶

solver.set_absolute_tolerance(absolute_tolerance: float)

Set the absolute tolerance of the linear solver.

set_under_relaxation_factor¶

solver.set_under_relaxation_factor(under_relaxation_factor: float)

Set the under-relaxation factor (URF) used for nonlinear iterations.

Args:

• under_relaxation_factor: Value in \((0, 1]\). Smaller values add damping and can improve robustness for strongly nonlinear cases.

set_frozen¶

solver.set_frozen(is_frozen: bool)

Freeze the solver and model state (no updates during solves).

Args:

• is_frozen: If True, the solver state is not updated during a solve.

Example¶

solver = model.get_solver()
solver.set_verbose(True)
solver.set_under_relaxation_factor(0.7)
