5.3.2. Workflow¶
Simply by the features of the use-case 1 and 3, the successful calibration cases can be submitted to the database. Similar to the use-case 1, the meta-data is created from the log_aspherix-calibration.txt file as well as the calibrated parameters, calibrated_params.txt.
With the above two files, one can setup any other DEM simulation with these sets of parameters. To assess the calibration workflow, the history of the quality function can be saved and then visualized within the workflow. It is not necessary to save all the working directories of all simulations, but the path to the storage location is stored in the metadata file.
