Hello,

I am a student learning Nays3DV in iRIC. My supervisor has given me a task to construct a channel with a weir inside it and run the simulation.

I am looking for guidance on the correct procedure to:

Create the channel geometry in Nays3DV.
Create and place a weir structure inside the channel.
Set the channel bed elevation and weir height.
Define the inlet and outlet boundary conditions.
Set the required water depth/flow conditions.
Run the simulation and visualize the water flow over the weir.
View results such as water surface, velocity, and water depth.

I have already studied some of the Nays3DV examples, but I could not find a clear example or video showing how to create a weir and channel from the beginning.

Could someone please provide a manual, tutorial, example file, or video explaining this procedure step by step?

I would really appreciate your help.

Thank you.
