用的windAroundBuildings算例，840万网格的二维模型，网格质量检查过了，计算域是14000*4000米。epsilonInlet 0.0003; // Cmu^0.75 * k^1.5 / L ; L =10
dimensions [0 2 -3 0 0 0 0];
internalField uniform $epsilonInlet;
boundaryField
{
INLET
{
type fixedValue;
value uniform $epsilonInlet;
}
}
kInlet 1.5; // approx k = 1.5*(I*U)^2 ; I = 0.1
dimensions [0 2 -2 0 0 0 0];
internalField uniform $kInlet;
boundaryField
{
INLET
{
type fixedValue;
value uniform $kInlet;
}

时间步长试过1 0.1 0.01 其他的都没动
