This report presents a new file format named EPP/EPT to store EUROPLEXUS results for subsequent post-processing. The new results format comes in two variants: a full version (EPP format) dedicated to the storage of complete EPX results, typically for the production of maps and animations, and a reduced version (EPT format), dedicated to the storage of selected nodal and elemental results, typically for the production of detailed (high-frequency) time curves. The storage is by default done in binary (unformatted) form to maximize space efficiency, but a formatted (fully human-readable) version of the results files is also available which can be useful for debugging purposes. The storage may be either monolithic or split into several files, one for each time station. The monolithic version is the default for the EPT format, while the split version is the default for the EPP format. The EPP/EPT results format is compatible with automatic growth of the memory (GROW model, see~\cite{460}) in simulations with Adaptive Mesh Refinement (AMR), a feature that was not offered by the previously available EPX-native results file formats (namely ALICE and ALICE TEMPS). Each data record is identified by a unique code (descriptor).This should facilitate adding new data to the EPP/EPT formats when new models are added to EPX, a task that had become very awkward and error-prone when trying to update the historical data formats (ALICE and ALICE TEMPS).
