OpenMI - Open Model Interface > Workshops on integration of the HEC-RAS and MODFLOW models using OpenMI > OpenMI_HEC-RAS_MODFLOW.png

Notes on some changes during last meeting:

Upgrade HEC-RAS and MODFLOW to OpenMI 1.4
Implement linking between MODFLOW and RAS using ElementMapper
- Groundwater Cell Polygon to River Segment Polyline (weighted sum)
- River Segment Polyline to Groundwater Cell Polygon (weighted mean)
Exchange flow into groundwater [cfs] from HEC-RAS --> source flow [cfs] MODFLOW
Exchange groundwater level [feet] from MODFLOW --> groundwater level [feet] HEC-RAS
Implement simple component to visualize exchanged values on a map in Tools
Fixing MEMORY BUG in MODFLOW when solution is not converging (... in progress)
Implement unit conversion in MODFLOW wrapper
Prepare more advanced examples with 50x50 MODFLOW grid
Add XY origin and Rotation for MODFLOW grid as project.xy file and implement calculation of cell polygons in the MODFLOW wrapper (maybe should be part of omi)
Extend GUI to send events in Java / C# way instead of async. queue based
Remove all river / channel - related knowledge from MODFLOW wrapper - better incapsulation, allow to map river sources on-the-fly using OpenMI instead.
Add custom blend configuration for a map
