Performance of interFoam on the simulation of progressive waves
@东岳 今天刚好在看limitedLinear格式,后面的数字貌似指的就是这一串,max(min(2r/k,1),0)
老师好,我用混合方法计算后台阶,采用div(phi,U) Guass linear 和 div(phi,U) Guass limitedLinear 0,瞬时速度场差距不小,div(phi,U) Guass limitedLinear 0依然存在明显耗散,小尺度不如div(phi,U) Guass linear丰富,理论上Guass limitedLinear 0和Guass linear不应该一致吗
不应该差距不小。上结果图看看
@李东岳 div(phi,U) Gauss limitedLinear 0;
div(phi,U) Gauss linear; Q=1e6
采用LUST 介于Guass linear和limitedLinear 0之间
div(phi,U) Gauss limitedLinear 0;
我还第一次见有人这样用。我下周找个小网格测试一下。
div(phi,U) Gauss linear;
另外你这个结果看起来不太对,有震荡
