May 2025: iConnect meeting
- Attendees included representatives from SKB and Obayashi.
- Topics discussed included DFN solute transport, transient particle tracking, upscaling at multiple resolutions and fracture removal.
November 2024: ConnectFlow 13.1 released
Selected updates in this version include:- Implemented transient particle tracking in DFN models. In this implementation, ConnectFlow will change particle tracking libraries at intervals specified by the user.
- Introduced new methods for specifying DFN fracture transport aperture in the GUI, including a default model which may be overridden for individual fracture sets.
- Implemented a standard transport aperture model for DFN matrix fractures.
- Updated Windows licensing system
- Introduced options in DFN fracture removal to allow removal based on the physical macrofracture rather than the tessellated subfractures.
- Added command to calculate the difference between the results of two CPM solves in the same model (e.g. with different boundary conditions or two timesteps from the same calculation) from CPM OUTPUT DATA.
- Added command to calculate the difference between the results of two DFN solves in the same model (e.g. with different boundary conditions or two timesteps from the same calculation).
- Added option to read multiple IFZ files under GENERATE ROCK PROPERTIES BY ELEMENT in CPM models, with each IFZ file applying to a different set of rocks.
- Added option to read RESCUE files as externals in the ConnectFlow GUI.
September 2024: Merger with Amentum
- Jacobs' Critical Mission Solutions and Cyber and Intelligence Units, which includes the ConnectFlow team, became part of Amentum on 27th September 2024.
December 2023: ConnectFlow 13.0 released:
Selected updates in this version include:- Added support for non-linear transient calculations, including salt transport in combined CPM/DFN models.
- Added support for automatic timesteps in combined CPM/DFN models.
- Added support for steady state unsaturated salt transport, and salt and heat transport, in CPM models.
- Implemented rock matrix diffusion in combined CPM/DFN models.
- Changed the default colour map in the ConnectFlow GUI. This can now be changed by the user in the file "properties" in the directory "default_host" in the installation directory. The previous default is now "basic_rainbow".
- Added functionality to allow comparison between CPM solve files without need for interpolation (i.e. where models are identical).
- Altered CPM permeability file writer to allow individual realisations of permeability to be written separately.
- Added support for IFZ and FAB fractures that are concave polygons in DFN models.
- Added keywords in CPM and DFN particle tracking to allow user to read start points from multiple files.
- Added option in CPM particle tracking to start points from start or end points in .ptb file.
- Added values of land area and runoff quantity in infiltration statistics files in CPM recharge-discharge boundary conditions.
- Added an option to define DFN dip direction as a bearing (measured clockwise from north) instead of an angle (measured anticlockwise from east).
- Added options to save KXY, KYZ and KZX in >> SAVE VALUES in CPM models.
- Added option to save multiple variables in >> WRITE FRACTURE SOLUTIONS TO TSURF in DFN models.
- Changed GUI particle tracking output to use >> CALCULATE PARTICLE TRACKS instead of >> PLOT PARTICLE TRACKS.
