The required technical features, hardware compatibility, licencing, and support necessary to meet NWS's needs. Capability to simulate groundwater flow and transport using a • Capability to simulate groundwater flow and transport within fractured rock, including Discrete Fracture Network (DFN) and Equivalent Continuous Porous Media (ECPM) modelling. • Capability to simulate hybrid models (part DFN, part (E)CPM). • Functionality for transport calculations, either as an inert tracer (concentration field) or through particle tracking algorithms. • Flexible import functionality to include geological and structural information, lithological bodies/surfaces, borehole information etc. • Gridding functionality suitable for DFN, CPM or hybrid models. • Flexible export functionality of model output to support integration with other work streams (e.g., post-closure safety). • Functionality for density-driven flow due to variations in groundwater salinity (e.g., through transport of a saline tracer). ## CPV classification Industry specific software package Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/e6e134de-46a8-47e6-aa9b-b34f4223fff3) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
