Hi, very good evening.
Some time ago I had asked for help to find a code configuration that would allow me to visualize the change in bed as a result of the interaction of the pipe and the wave forcing (that is, scour). Following said indications and suggestion from the other time, I have refined the code in the following way to try to find what I need. (Lo in the attached image). I understand that a module for sediment transport is still being developed. According to the theory and the help answers from the other time, they have made me put together the code that I show up to now, having the current image which did not make the sediment bed change under the pipe. For example, I have taken a good look at how to determine the Shields parameter using the diagram as a function of the Reynolds number or the characteristic diameter D50 property of the sediment, depending on the wave condition. I have determined the wave height to start the incipient movement in the sediments with the help of the formulation proposed by Van Rinj. Am I entering some parameter or command inappropriately or am I missing some important command? Or am I not displaying the simulation output correctly through Paraview? Other Query: There are no concrete examples to use the S 73 command. How could this option help me to move sediments since, for example, it admits 3 arguments, right? For example I would tentatively add as follows. S 73 0 8 0 followed by x-origin and y-origin where the first argument is that it is the coordinate z = 0 (where the sediment layer begins), the second corresponds to a distance... I would put 8 according to the numerical domain and finally 0 which is an angle. The x-origin and y-origin coordinates. I am not clear where to place them or how to enter them. Greetings, thank you very much for the help of the other time, and waiting again one more time. Control.txt.
