Cannot running sediment flow simulation

Can I get some help? I want to run a sediment flow simulation in an open channel, but this isn’t work. I have to run another model of obstacle and that’s worked.

    Can i asked about the Obstacle: How does it work ie its restricts the flow completely or partially and how can i specify the size and location of the obstacle.
    What is the difference between Obstacle and fixed bed in to initial? Please could i know about it in details. Could you please inform me that how can i show the velocity field in the Nayas2DH for velocity magnitude?

    Obstacle restricts the flow and sediment transport completely. You can specify the location of obstacle everywhere in the computational domain, but the size of obstacle is set based on the grid size you set.
    Fixed bed is the unerodable bed like concrete. The sediment can deposit above it, but no erosion is considered for this cell.

    Flow or Temp time series date is not sufficient to run requested time window.” This one has been around for a while, but it just showed up again on the Facebook HEC-RAS User’s Group, so I thought I’d show the fix(es) here. This applies to the new beta version of 5.0, as well as previous versions of HEC-RAS that can run sediment transport.
