Hello everybody
I started working in a project on ArcGIS, when i used "LongestFlowpath" tool (in HEC GeoHMS) I got an error with this message :
System.Runtime.InteropServices.COMException (0x80040215): Exception from HRESULT: 0x80040215
at ESRI.ArcGIS.Geometry.IRelationalOperator.Contains(IGeometry other)
at ESRI.APWR.ApHydro.ArcHydroOp.ComputeLongestFlowpath(ApLayers apLayers, Int32 debug, ITrackCancel& trackcancel, IGPMessages& messages, String& exMessage, IRaster costRaster)
Failed to execute (LongestFlowpath).
Does anyone has any idea what might have caused it?
I would really appreciate your help
Thank you very much

Hello Sir, thank you for your reply
I already tried all the solutions given in the "known issues" section but it stil does not solve my problem
The cause could be a number of things. Working with your mxd and other data on your local box and not over a network saves time and eliminates errors. There are several tips at https://community.esri.com/thread/43771 that might be helpfull.
