Hello,

I was testing the lagrangian/sprayFoam/aachemBomb tutorial to check if it is possible to spray solid particles instead of fluid particle. But I am getting the following error:

Code:
Exec   : sprayFoam
        
        
        ...
        
        Starting time loop
          
          Courant Number mean: 0 max: 0
          deltaT = 2.94118e-06
          Time = 2.94118e-06

I did only two modification in the tutorial:
1) in the constant/thermophysicalProperties I commented the C7H16 in the liquid subdictionary, and I added C in solid:

Code:
liquids
        {
        /*
            C7H16
            {
                defaultCoeffs          yes;
            
            }
        */ 
        }
        
        solids
        {
           C
            {
                defaultCoeffs   no;
                // if  defaultCoeffs no        properties should be :
                CCoeffs
                {
                           rho                     9000;  // Density [kg/m3]
                           Cp                      462;   // Specific heat capacity [J/(kg.K)]
                           K                       0.04;  // Thermal conductivity [W/(m.K)]
                           Hf                      0.312e+06;     // Heat of formation [J/kg]
                           emissivity      0.28;  // 1;  //         Emissivity  
                }
            }
        }
2) in the sprayCloudProperties file :

Code:
    phaseChangeModel none; //liquidEvaporationBoil;
        
            singlePhaseMixtureCoeffs
            {
                phases
                (
                    solid
                    {
                               C                       1;
                    }
                );
            }
but I get the above error.
What should I change to set this tutorial with a spray of solid particles?

SprayFoam is hard coded to use "SprayClouds" and only fitted to use liquid. It has sub-models such as - atomization model and
  • break-up model which only apply to liquid droplets.
In order to use particles you need to use the other Lagrangian solvers.
