Dear Foamers


I am trying to simulate evaporating droplets. I am capable to simulate my velocity field without paticles. However I encounter an error after adding this to my controlDict.

functions
{
    thermoCloudInfo
    {
        type        cloudInfo;
        libs        ("liblagrangianFunctionObjects.so");
        clouds      (thermoCloud1);
    }
}

My cloudProperties file is given below:
