|Summary||0003087: wave simulation crash if inlet speed is lower than wave velocity!|
|Description||In the cases that wave speed defined at inlet is lower than calculated water particle velocity (calculated from wave parameters) solver will crash after some iterations. For example a case setup as bellow where wave speed defined to be zero and water particle velocity at surface can be calculated (analytically) as 0.7 m/s:|
origin (0 20 0);
direction (1 0 0);
|Steps To Reproduce||I have checked this problem under different scenarios (for 2D and 3D) and always got the same results. It seems other engineers are experiencing the same problem as well. |
Problem occurs both for OF 5 and 6. I have attached a sample case in 2D for your consideration.

Reversed flow is more difficult to get right, but the tutorials/interFoam/laminar/wave case runs to completion with the speed set to zero, so the problem is not fundamental, it is with your case.
See https://bugs.openfoam.org/rules.php. "Reports that indicate a significant possibility of user error will be closed or deleted.".
