Basic Controller

class pyrefine.controller.basic.ControllerBasic(project_name, pbs=None)

Bases: ControllerBase

Multiplies the complexity every steps_per_complexity steps by a fixed factor, complexity_multiplier. The default behavior is to double the complexity every 5 steps.

Parameters

  • project_name (str) – The root name of the project (without any mesh numbers)

  • pbs (PBS) – PBS queue helper

steps_per_complexity

The number of meshes per complexity. The default value is 5.

Type

int

complexity_multiplier

the multiplier applied to the complexity when the complexity needs to be updated. The default value is 2.0.

Type

float

compute_complexity(istep, current_complexity)

Basic complexity schedule that will double the value after n iterations

Parameters

  • istep (int) – Adaptation step number

  • current_complexity (float) – The current complexity in the driver. If doing a restart, the current complexity will be None

Return type

complexity

compute_iterations()

Computes number of iterations based on initial and final complexity which both need to be defined. Final complexity must be equal or greater than initial complexity.

Return type

iterations
