there is a new problem with my spillway .
I changed the inlet velocity to 0,0976 m/s to get a volume flow of 0,23 m³/s.
Booth simulations run with the same Mesh and the same settings except the end time and the wirte intervall.
- Run 5; 10 s sim. duration; 0,5 write intervall
- Run 6; 5 s sim. duration; 0,25 write intervall
In Run 5 there is some kind of an error at 3.5 seconds, all of a sudden the water is everywhere in the geometry.
In Run 6 the simulation runs straight without any errors to 5 seconds.
Here is a Video:
I can’t explain the behavior. If it were in both runs, I would say that it is due to the missing y+ layer. I have to calculate and add this layer. Why does the model calculate once only up to 3.5 seconds and once up to 5 seconds, with the same settings ?
