Dear Seniors, recently I use 40 computing cores to calculate a scour project, but when I read the results, I found that there was a scour phenomenon at the flow rate entrance, as shown in the following figure1:
And the location where initialize appears is just at the junction of the computing block, as shown in the figure2.
I would like to ask how to eliminate this phenomenon. Finally, attach my control file.
Thank you for your selfless help and give you my sincerest regards.

Hi. That should have nothing to do with the number of cores use. It looks like a boundary condition problem that can appear with scour simulations. Try using S 73 to stabilize the sediment near the boundary.

OK, I'll try what you said, thank you sincerely.
