Howdy Yall,

I was able to get the kinematic cloud merged with Sonic foam and achieved some visually agreeable results for the ma 3 forward facing step tutorial. Momentum is coupled and the results look, upon visual inspection, good.


The problem is that I am trying to incorporate heat transfer now and I switched from kinematicCloud -> thermoCloud. From my understanding thermoCloud should just add some functionality and act as a wrapper to kinematicCloud. I made some modifications to the creatFields.H file and coupled the cloud to the continuum energy equation through (+ dustCloud.Sh(e))

My code compiles and I go to run my test case, the simulation proceeds as normal except for the fact that once the particle injection time is reached, the simulation crashes without an error.

Specifically it crashes on the evolution step of a particular time step.

I am attaching my case files in this top post and will make a comment that has my code files

Pardon the language in my log text.

Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[18412,1],1]
  Exit code:    144

It should be noted that this error is just an MPI error and running in serial will have the code crash on "Solving 2-D cloud dustCloud"

I've seen it mentioned on the forums that the lagragian wall rebound treatment can couse hanging, though I am crashing, if the mesh is trash near the wall. Despite not using the rebound model I checked the mesh just to make sure it wasn't the cause using> checkMesh -allGeometry

The output of the check is:

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

Given the lack of an error code, the complicated nature of the Lagrangian source code and my, relative, inexperience with openFOAM solver programming I'm quite at a loss here.

I know that this has to caused by user error, but I haven't pinned down a specific reason for why within the lagrangian evolve() function

if you want additional files I'll upload them in the comments if it is requested.

Thanks yall!

Hey there, the error is a bit unprecise. What is the error message when running in serial mode? Maybe you could try using gdb to output more information regarding the error and its backtrace?
Code:
$gdb yourApplicationName
then use the command
Code:
run
inside gdb and after it crashed
Code:
bt
to see at which point the program stoped to work.

Ok, so if I understand you correctly: The application just stays in some kind of endless loop and you have to kill the job manually?
Just looked over your injection model setup. It looks like you are injecting with 40 kg/s. From your simulation I can also see that the timestep used seems to be 2e-4s, which would mean a total of 8e-3 kg injected per time step. With your additional size distribution and an estimated density of 1000 kg/m3, I estimated the total of number of injected parcels per timestep to 45 million. That would basically explain the "freezing", which would be in fact just a very, very long computation (until your computer runs out of memory ).
Maybe have a look at the way this type of injection should be used.

If the process simply froze and was stuck calculating, your logic would be sound. However, the process simply dies.

there is no process to kill once it get's to this point.

openFOAM simply dies

Ok. Can you then try to use a simpler injection model (like manualInjection)?

Did that,

and it freezes at the same place.

New injection model:

        {
            type             manualInjection;
            patch            inlet;
            duration         1;
            parcelsPerSecond 13905;
            massTotal        40;
            parcelBasisType  fixed;
            flowRateProfile  constant 1;
            nParticle        1;
            SOI              0;
            positionsFile   "dustPositions";

            sizeDistribution
            {
                type        fixedValue;
                fixedValueDistribution
                {
                    value   0.00007;
                }
            }

Can the Cloud Evolve?

Yes

Starting Pre-Evolve
It gets to the .preEvolve() function. I'll keep digging to find where it dies :/. couldn't get gdb to recognize the OpenFOAM command and this computer will take hours to recompile in dubug mode so I am going to debug, in what I assume is, the idiots way (Brute Force Comments).

I appreciate your suggestions / help thus far though

So the code fails at the following:

line 211 of:

src/lagrangian/intermediate/clouds/Templates/KinematicCloud/KinematicCloud.C

the function: injectors_.inject(cloud, td);

still trying to figure out where to go from here

Try this config maybe. I know that it works well for me.
Code:
injectionModels
    {
        OneSingleDroplet
        {
            type            manualInjection;
            massTotal       6.038715e-07;
            parcelBasisType mass;
            SOI 0;
            positionsFile "cloudPositions";
            U0 (1 0 0);
            sizeDistribution
            {
                type        uniform;

                uniformDistribution
                {
                    minValue        4e-5;
                    maxValue        4e-05;
                }
            }
        }
    }

That doesn't work either :/

I am inside the injection function:

lagrangian/intermediate/lnInclude/InjectionModelList.C

and have found my code doesn't get past this section:

Code:
forAll(*this, i)
    {
        this->operator[](i).inject(cloud, td);
    }
So it is definitely something to do with the particle injection.

What do you mean by "your code"? Did you change your standard openfoam installation?

I didn't change the standard installation. Though, I am trying to combine ThermoCloud functionality with sonicFoam like I was able to do with KinematicCollidingCloud and sonicFoam.

this is a custom solver.

By adding the line:

Code:
Info << "\n" << this->operator[](i).massTotal() << endl;
before:

Code:
this->operator[](i).inject(cloud, td);
The solver reports that the total mass is 6.038715e-07 before it crashes.

so I know that it is taking in the cloudProperties input that you suggested
