rhoCentralFoam发散，出现Maximum number of iterations exceeded

[Rachel0096]

在使用rhoCentralFoam求解器时，出现如下错误，想请教一下是什么原因呀


以下是我的一些设置：
p:

dimensions      [1 -1 -2 0 0 0 0];

internalField   uniform 1;

boundaryField
{
    inlet
    {
        type            zeroGradient;
    }

    outlet
    {
        type            fixedValue;
        value           uniform 1;
    }

    bottom
    {
        type            zeroGradient;
    }

    top
    {
        type            zeroGradient;
    }

    defaultFaces
    {
        type            empty;
    }
}

// ************************************************************************* //

T:

internalField   uniform 1;

boundaryField
{
    inlet
    {

        value           uniform 1;
    }

    outlet
    {
        type            zeroGradient;
    }

    bottom
    {
        type            zeroGradient;
    }

        type            zeroGradient;
    }

看了云图以后发现，应该是温度值出现极高值后导致计算发散，不知道应该如何修改呢？

[李东岳]

就是发散了，这个也不太好debug ..

[尚善若水]

@Rachel0096 rhoCentralFoam步长不能太大，先调小试试看

[Rachel0096]

@尚善若水 已经试过将时间步长调小，但作用不是特别大，最后还是会出现上述问题

[Rachel0096]

应该是我的边界条件设置的不合理，我修改了物性和边界条件以后，目前是能继续算下去的。
