Tip

Key Achievements

  1. Enhanced/extended industrial engagement

  2. Agreement on definitions for benchmarking, validation, verification and DEM challenges to be adopted across all Working Groups and ON-DEM deliverables.

Focus for next period

  1. Categorisation of problems into benchmarking, verification, validation and/or challenge.

  2. Precise definition of problems for external (and internal) promotion.

Note

Input needed from other WGs

  1. Help from WG6 in dissemination to get further engagement on benchmarking, validation and verification problems.

  2. Communication from WG1 and WG5 on relevant problems which require joint work (e.g. industrially relevant problems).

  3. Details of common DEM output file format from WG3 to be adopted in benchmarking, validation and verification campaigns, where possible.

Brief Summary

Extensive discussion in order to agree on a common terminology. Agreement reached and to be adopted within ON-DEM context as follows:

Benchmarking: Comparison between two or more codes (e.g. in terms of performance, accuracy, etc.)

Verification: A given code does what is supposed to. Verification is provided by means of an analytical solution (if available) or in terms of the ability of the code to replicate the relevant physics.

Validation: A given code agrees with observed reality. Validation is usually provided by comparison against physical experiments/measurements.
