Processes

This section intends to describe what is a process in Kratos and the different interfaces that are available from python.

Description

Processes in kratos are a set of utilities that will be executed during an AnalysisStage. The main characteristic of the procsses is that they have a set of fixed execute points (see AnalysisStage Sequence Diagram):

• ExecuteInitialize: Will be called during the initialize sequence of an AnalysisStage, before the initialization of the Solver.

• ExecuteBeforeSolustionLoop: Will be called during the initialize sequence of an AnalysisStage, after the initialization of the Solver

• ExecuteInitializeSolutionStep: Will be called at the begining of each solution loop, before executing the preconditioners and solvers

• ExecuteFinalizeSolutionStep: Will be called at the end of each solution loop, after executing the preconditioners and solvers but before the output stage.

• ExecuteBeforeOutputStep: Will be called at the begining of the output stage for every output process active, before printing the results

• ExecuteAfterOutputStep: Will be called at the end of the output stage for every output process active, after printing the results

• ExecuteFinalize: Will be called during the finalize sequence of an AnalysisStage, just before existing the stage.
