Released 18 March 2016
| Sector | Item | Description |
|---|---|---|
| Graphical interface and parameter assignment | In/outflow on top/bottom (IOFLOW) parameter supported for any type of mesh (partially or fully unstructured) | For non-layered meshes, top or bottom faces are identified by their orientation with respect to the horizontal X-Y plane (taken as reference to define which faces are top and which are bottom). Boundary faces of elements having non-zero IOFLOW coefficients are analyzed and if they appear to be perpendicular to the X-Y plane (at the 1% angular threshold limit) they are consider to be "vertical" and are thus not accounted for. If not, they a re or top or bottom faces and integration of the IOFLOW is performed. |
| Default settings | Derivative calculation for the evaluation of the capacity term in unsaturated flow | Default has been changed from 'Chord-slope scheme' to 'Analytic Derivative', hereby avoiding unnecessary budget errors. |
| Internal | Spatial tree for older files now generated at loading a file | FEFLOW internally uses a spatial tree for addressing different geometrical features. Its format has been changed between versions 6.2 and 7.0, so that when using older files, the spatial tree has to be created from scratch. This is now done when loading the fem or dac file rather than when the tree is needed for the first time. This change leads to a longer load time of such files, but avoids the misimpression that FEFLOW is stuck at certain operations that require the spatial tree. To improve performance for future file loading, it is recommended to convert older models to FEFLOW 7.0 format. |
