ON-DEM Benchmark Definition Template

ON-DEM Benchmark Definition Template

Please delete text below when you make your template.

Before completing this form/template, please consider the nature of the comparison that you will consider. We have adopted the following definitions:

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

  1. 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.

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

  3. Challenge: Where experimental measurements are made independently, and these are simulated using a given DEM code. The simulation results are then independently verified against experimental results which were not known by the people simulating them.

Benchmark Lead(s)

Add/remove rows if necessary please use

Confluence profile tags (e.g. @Daniel Barreto )

Confirmed collaborator(s)

(At least one collaborator in addition to lead(s) is required. Every benchmark must consider at least two different DEM codes). Add rows if necessary.

Benchmark Geometry and Boundary Conditions

This should be ideally provided as a file(s) stored in a repository (provide details below adding/removing rows if needed). Where appropriate, also include a relevant image of the problem, and additional notes here.

 

Please describe/specify boundary conditions (rigid boundaries, periodic boundaries, stress and/or strain control:
