3DSL v2025.1104

Enhancements

1. Improved streamline tracing algorithm across faults in the X and Y directions when multiple non-neighbor connections are present.
2. NNC keyword allows to specify the absolute value of the transmissibility between two non-neighbor connections. This is needed for the case where their adjacent faces do not overlap and would otherwise result in a zero transmissibility.

Bug Fixes

1. If additional transmissibility multipliers (TXMULT, MULTX, MULTFLT etc) are provided, their harmonic average between two faces was used in the transmissibility calculation rather than their product. Now the product of the multipliers between two faces is used.
2. If NNCEGRID=F before reading a .INIT file and then transmissibilities were also provided in a .INIT file, the transmissibilities from the .INIT file were being used rather than recalculating all transmissibilities.
3. If NNCEGRID=T but additional transmissibility multipliers were read later, the additional multipliers were ignored. 3DSL now issues a warning that NNCEGRID is being reset to F and transmissibilities are being recalculated.
