Revision	Date	Description
36	3月 3, 2026	Added a tolerance in determination of open joints. 1e-6 of the spring force is selected as the tolerance The loose node criterion now applies to both new and existing events when they are being combined Fixed typos in parametric study dialog Fixed restore of stress histories Improved combine events and fixed joint name during export of microcracks Fixed bug in grid not being loaded after model reset Modified microseismic clustering algorithm. The actual areas are used instead of the equivalent circle area. The product of area and slip magnitude is used as a weight factor when calculating the event location Fixed bug in pipes plot item not showing apertures properly Added joint forces/stresses to joint contour forces plot item
35	2月 6, 2026	Updated wellbore sign conversion when moving its position Seams and joints are now separate on sketch model based on their name
34	2月 3, 2026	DFX seams/joints will now be translated first before being rotated Default draw mode for microseismic events is now On instead of On rotation Improved combine slip events performance and results
33	1月 26, 2026	Fixed a bug in the calculation of the sink power. Fluid properties are used instead of solid properties Clustering microseismic events now allows users to set the range for event magnitude Fixed bug in parametric study data for slurm scripts Fixed bug in parametric study dialog only occuring in linux build Linux building on Rocky 8 Inactive microseimic events can now be deleted by providing the minimum magnitude for slip events, added to batch, reset and gui
32	1月 14, 2026	Added pressure loss calculation option for perforated tunnels Fixed microseismic events not being removed when resetting them Microseismic events are now recorded properly by disregarding springs that have both loose nodes Small fix to compile with new version of compiler Improved error handling for initialization Clusters set to active with 0 nodes will now throw out an error during initialization
31	11月 21, 2025	Fixed bug in dfn leading to fractures with grid points outside of the model to be excluded Added stress history plots Fixed pipe export only showing one pipe Demo message only shows up once when running in interactive Fixing initialization of connectedDFN_ in sketch model Improved connected DFN on sketch model performance Improved microcracks export when exporting with open fractures, exporting with natural fractures now provides only fractures with permeable springs
30	4月 30, 2025	Added support for exporting only connected microcracks with grid Added option to render only FRACMAN DFN with connected pipes
29	3月 28, 2025	Added auto create initial cracks on clusters feature Fixed mpi crash if running thermal without fluidjoints Fixed crash during initialization of mpi Added option to reduce matrix stiffness from the start simulation and batch Minor bugs fixed in batch Improved volume calculation when approximate pressure gradient is selected Fixed small bug in start simulation dialog and in bore hole segment dialog
28	3月 12, 2025	The reference stress correction included in the wellbore pressure initialization. Fixed issue with well segment not being translated and rotated properly Matched the sign convention with dfn translation when trasnlating well segments Fixed issue with pressure initialization when not being checked on ui but still causing it to change the initial fracture pressure Fixed cluster nodes plot item not considering reference stress for some nodes Added reset casing/cement temperature to batch and reset lattice Updated cellspace to avoid crash with large models
27	1月 24, 2025	The advection time step calculation after resetting the multiplication factor is now done based on fluid elements, not pipes Added calculation of the contribution of the convective heat transport to the advection critical time step The calculation is done within pore pressure change loop and in the separate function called when the advection time step factor is changed from GUI Thermal multistepping now starts multistepping right away as opposed to a few non multi steps first Fixed crash related to stimulated area and fracture area histories
26	1月 20, 2025	If resolution ratio between global resolution and smallest resolution is greater than 20, the ajusted ratio will now have a more gradual increase Fixed bug in calculation of inflow and outflow rates for fluid elements Fixed sink histories, variables are now always accumulated regardless of history interval Fixed crash on mpi when model does not have fluid nodes Fixed reset temperature not working for console version Fixed shear and normal stiffness being reversed for fracman
25	1月 8, 2025	Proppant volumes instead of concentrations are used during proppant transport calculation. Old volumes are reset in the function that updates proppant concentration due to volume change (and does propopant stress calculation) Fixed sink histories only showing 0 Fixed the bug causing instability in propped fractures Old volumes of fluid elements are reset outside calculateProppantStress function. The change preserves correct old volume for the simplified fluid calculations Fixed save/restore for sink histories and proper reset of their values per cycle Added history interval to save/restore During excavation cleanup, fluid nodes and pipes are resequenced into sequential order to avoid issues for mpi
24	12月 19, 2024	Added factor of 0.7 to implicit aperture calculation Error calculation for implcit logic now uses relative error instead Excavated nodes properly restored for mpi Tension events are assumed to be finished when restoring model in mpi
23	11月 13, 2024	Fixed thermal calculations Added implicit convergence factor to save/restore Added seq number to pipe plot item reset segment temperature save/restore now works fixed bug leading to stretched pipes appearing after save/restore following the excavation of pre-existing fluidjoints
22	8月 29, 2024	Added option to generate Slurm script instead of SGE Forces are not initialized in the joint springs for the Voronoi lattice. Forces in those springs should be generated during mechanical equilibration. The force initialization previously used resulted in relatively large force fluctuation and tensile forces, even for all compressive stress states. The force/displacement function is simplified. The check for spring state is done in one place, at the end of the function. The tensile strength and cohesion factors are refined.
21	8月 2, 2024	Added set maximum proppant stress to reset lattice Restored proppant concentration changes Restore get permeability changes
20	4月 30, 2025	Fixed signal for segment temperature Microcracks exporter now checks if data is within the model extent Added matrix time step to simulation time Fixed multithreading bug on permeable dfn Added fraction of pressure increase to reset lattice

6	9月 12, 2023	Building w/ CMake Using Github for subversion control Fixed issue with wrong fluidnodes being calculated in implicit logic Only fluid elements inside the perf tunnel or completion wil be skipped on the implicit calculations Fixed bitmap exporter Fixed dialogs for borehole import and wellgeometry import
5	7月 31, 2023	Fixed display of demo mode watermark. Enhanced console license security.
4	7月 20, 2023	Fixed UI bugs causing crashing. Added heat advection multistepping.
