Hello everyone,
I did a code using Muscl scheme, everything looks like good,but I found the slope limiter might Limit the physical dissipation. I had tried mang limiters such as 1 Minmod 2 Superbee 3.MC limiter 4.van leer 5.van Albada 6.symmetric minmod. However, when the grid size change from 1m to 0.2m, the pressure gradient of wave significantly change, which is biger than experiments. if the grid size is 1m, the gradient agrees well with experiments. why? the smaller the grid sizes is, the biger the error is. Please give me more advices and discissions. Thanks! honglin |
