Output Processes

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

Description

Output Processes in kratos, like process, are a set of utilities that will be executed during an AnalysisStage. The main characteristic of the output process procsses is that in addition to the regular execution points of a process, they have an additional fixed execute point PrintOutput and a function to evaluate if the current step is valid for printing IsOutputStep . For more information 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.

• PrintOutput Will ve called during the print sequence of the AnalysisStage if the print condition is meet.

• IsOutputStep Will enable (true) or disable (false) the print condition.
