Re: Unsteady model error - "Matrix Solution Failed"

*try setting a minimum flow

*check the XS Htab Param.: use the max number of points, smallest interval possible for the expected WS. if the flow very low, use the channel minimum elev as the starting El (the default is a foot higher).

*as hotstart, use a stage hydrograph as lower boundary condidtion, starting from high stage and decreasing.
