Users are invited to upload numerical calculations, performed with the forcefields definitions present in the database, in the form of a general description of the problem, numerical input files, the simulation code used and the cementitious system under consideration. For each calculation, an arbitrary number of scalar ‘results’, formed of a real value, an estimated error and a unit, can be entered to represent the physical parameters extracted from the numerical simulation. Similarly, users can upload relevant benchmarking data, from experimental or ab-initio studies, alongside the corresponding measured scalar parameters and errors estimates. Finally, the web application provides a powerful tool that allows a visual comparison of the parameters, corresponding to an arbitrary selection of force-field based calculations and benchmarks, by presenting these latter in a table with automatic unit conversion and their relative deviation to other comparable values.
