FEFLOW 8.1 Update History
In the following, all relevant software changes between the release version 8.1.0 and the current update are listed.
Update 8.1.2
Released on February 21, 2024
New functionality
| Sector | Item | Description |
| Supermesh | Supermesh Processing panel | New default value (120°) for Sharp angle is used now to preserve triangulation of 3D Supermesh during Supermesh Repair and Remesh. |
| Supermesh | Snapping Functionalitiy in 3D | Snap to Points, Lines and Faces methods have been extended now and they can operate on the 3D Supermesh geometry as well. |
| Geothermal | Input type and values for Borehole Heat Exchangers | The assignment of input type (i.e. inlet temperature, temperature difference, power and energy) as well as its input value has been revisited and made consistent throught the graphical interface. The BHE Editor contains now additional explanations (tooltips) of the different user options. |
| Geothermal | Heat Input Rate (deprecated) | The assignment of Heat Input Rate as boundary definition for Borehole Heat Exchangers is not anymore supported. The user should prescribe the Inlet-Pipe temperature via any of the following options: inlet temperature (prescribed value), temperature difference, power or energy. |
| Problem Settings | Legacy settings | A new section Legacy Settings has been introduced in the Problem Settings dialog, which will be used to list software options soon to become deprecated. |
Fixed issues
| Relevance | Fixed issue |
| Medium | Several bug fixes and major improvements in Supermesh Processing methods and 3D mesh generation (Update to Geode-FEFLOW 3.2.18) |
| Medium | Fixed the initialization of coordinate system offset after runing Geode's 3D mesh generator. |
| Medium | The issue of Drain/-fillable porosity parameter being NAN after changing Problem Class has been fixed. |
| Medium | Time Span for the assignment of Energy (Time-Series) was active in the BHE Interconnector dialog. The input field has been corrected. |
| Medium | The units of parameter "Volumetric heat capacity (Fluid)" were not consistance. The unit conversion has been improved. |
| Medium | Well BCs were deleted from the Result DAC file after inactivation of boundary nodes. A new handling Inactive Wells via the Well Manager has been implemented. |
| Medium | Select By Expression: Functionalitiy has been improved. |
Update 8.1.1
Released on December 8, 2023
Fixed issues
| Relevance | Fixed issue |
| Medium | FEFLOW application terminated after changing the problem class. This misfunctionality has been corrected. |
| Medium | Open Loop implementation in the Well Manager now supports the problem class "Unconfined - Phreatic". |
| Medium | Switching between different internet licenses caused that FEFLOW main application did not respond. The issue has been fixed with a new implementation. |
| Medium | FEFLOW main application closed after deleting a group of observation points. The crash has been corrected. |
| Medium | Several software terminations by using the 3D Layer Configurator has been corrected. |
| Low | Tooltips have been included in the new Observation Data dialog. |
| Low | Inspection panel is now activated and displayed upfront every time the Inspection Tool is used. |
| Low | The order of arguments for FEFLOW Python API (pdf.setProblemClass) has been now re-defined. |
| Low | Properties of the mesh generators are saved correctly in the 2D Supermesh document. |
| Low | Error "Cannot initialize Python interpreter in Linux" has been fixed. It is not required anymore a Python installation to only execute the FEFLOW console. |
| Low | Legend in views is updated without any observable delay. |
| Low | Inspection of In/Outflow on top/bottom, drain/-fillable porosity and source/sink is supported again. |
| Low | After deleting 3D Supermesh elements, now the selection is cleanup. |
| Low | Fixed issue of empty fields on BHE Dataset after exporting the boundary conditions. |
| Low | Deletion of BHE boundary conditions have been improved. |
| Low | Fixed issue on the parameters being passed to Geode volumetric mesh generator. |
| Low | A mesh consistency check has been added to the input surfaces before these are used for the 3D Supermesh Surface Bounding Box tool. |
Update 8.1.0
Released on November 22, 2023
New functionality
| Sector | Item | Description |
| Map Support | A new CAD support | Import and export the latest version of DXF and DWG files. |
| Wells | Well Manager | Well Manager introduces the possibility to group wells and apply operational rules. |
| Geothermal | Well manager - Geothermal extension | Create geothermal open- and closed-loop system within the Well Manager. |
| Results and analysis | New Observation Data dialogue | All the modelling results (observation points, nodal budgets, and content analysis) centralized into one FEFLOW's dialogue |
| Python | New Python module PySMH | A new module to create a Supermesh, run the 2D mesh generator and extend the model to 3D using interpolation methods. |
| Python | Cross-Section Generator | New documents methods to create cross-sections from a polyline. |
| 3D Supermesh | 3D Supermesh Tools | Several tools to create 3D geometries, select, edit and delete Supermesh Elements. |
| FePEST | Observation Definitions | The Observation Definition concept is extended now to work with Groups of Observation Points. |
