For the problem of sediment erosion by the flow around the pier, no abnormality was found in 150 minutes, and obvious asymmetry was found behind the pier in 160 minutes, with abnormally raised sand sills. I'd appreciate some guidance.
In addition, is it necessary to set the size of both flow and velocity? My colleague told me that setting only the flow rate will make the calculation abnormal. I want to confirm this. control.txt ctrl.txt 160min.jpg |

Maybe the problem is related to the non-uniform mesh?
For CFD, I recommend a CFL number of 0.3. Keep S 32 4. |
