Hi There,
i have downloaded icoLagrangianFoam and changed things so that it works on OpenFoam1.6 (I attached it below). I copy pasted the modified Files and added the necessary "# includes header.h" to a copy of the reactingFoamsolver... It works all fine to a point where he tries to compile: Code:
IncompressibleCloud cloud(vpi,U); Code:
myReactingParticleFoam.C:(.text+0x1aed): undefined reference to `Foam::IncompressibleCloud::IncompressibleCloud(Foam::volPointInterpolation const&, Foam::GeometricField<Foam::Vector<double>, Foam::fvPatchField, Foam::volMesh> const&)' myReactingParticleFoam.C:(.text+0x52cb): undefined reference to `Foam::IncompressibleCloud::~IncompressibleCloud()' myReactingParticleFoam.C:(.text+0x5f45): undefined reference to `Foam::IncompressibleCloud::~IncompressibleCloud()' The destructor is also defined in "incompressibleCloud.C". So why does it work with the icoLagrangianFoam and not with the reactingFoam? I would appreciate any help!! THX! p.s.: The incompressibleCloud.C looks like this Code:

The use of that is discouraged as since 1.5 there are facilities in OF that make most of it obsolete. If you want an example how particles can be added with 10 lines of code or so (most of those are needed to make the particle believe that they are living in a compressible solver) to a normal solvers have a look at https://openfoamextend.svn.sourcefo...agrangianFoam/ which offers basically the same functionality

Hi Bernhard (and other qualified persons),
so I have played around a little with it..as usual I did not get far. I added "basicKinematicCloud.H" an constructor for my cloud and an term to the Uequation. Also a file in my case, so it knows where to inject.. It compiles and is running. So I have some questions. 1. It does not write out any data (the tutorials write out the "lagrangian" folder as I would like it). How do I make him write the lagrangian Data? 2. the running solver says the following for each timestep: Code:
Cloud: ParticleCloud Total number of parcels added = 18 Total mass introduced = 0.0001 Current number of parcels = 0 Current mass in system = 0 3. general question: where are the equations for the lagrangian particles solved/ how do the move ?? Best

Hi Bernhard,
thanks again! Elvis seems to be pretty quick!! The domain is 1m. Maximum speed is 53m/sec which leads to a minimum residence time of 0.018867925 sec. Time step size is 2.5e6sec. .. Im a little confused..if elvis travels upstream, would be strange...of he leaves through the sidewall(wedge), but there is only the jetspreadingvelocity in radial direction(towards sidewall) so... Code:

Hi Bernhard,
me again... I figured it out.. ELVIS does not like to sit on the inlet patch ...then he seems to be scared and does not enter the domain. I placed ELVIS inside now and it is running fine. Thanks again and have a nice weekend! Cheers!!

I have compiled the icoLagrangian foam under OF 1.6 and I have two questions regarding this solver.
1. I am wondering why the particles are not leaving the computational domain when they reach the outlet of my test case. How and where do you define your outlet as a particle outlet too? 2. I am running into trouble running the case in parallel. Is there any known bug and/or solution to the problem? Kind regards, Antonio The icoLagrangianFoam was compiled as described in: http://www.tfd.chalmers.se/~hani/kur...m_reviewed.pdf

@1: any _patch_ should force particles to leave. walls bounce it back @2: there seems to be an issue, but for the reasons given above I never investigated it thoroughly But all this has been discussed elsewhere on the forum. LKook for icoLagrangianFoam and sort the results by time

Hi Bernhard,
Thank you for your answer and advice. I will probably follow as you say, however I do have one question. The HardBallParticle.C .H and respective clouds are nowhere to be seen in the OF 1.6 version. Are there any alternative and similar clases I should use? Kind Regards, Antonio

You could have a deeper look in the solidparticle.C/H or the submodels of the sprayclasses. They seems to be very similar.

Hi Senior Member,
Di you have any luck embedding the intermediate lagrangian libraries into your solver? Any example you could share? As far, i have not had any luck. Kind regards,

Hi Foamers,
I have a very strange fault in my simulation. When I try to run a simulation with particles m>10^12 kg the small particles stick on the wallpatch! What's wrong with my case? I vary the restitutionscoefficient e between 0 and 1 with the same results. With heavier particles the case runs well.

I'm intending simulate a multiphase flow in a cilyndrical bioreactor. The tank is composed by a tangential inlet and an internal outlet. I plan to simulate a flow with homogeneous particles with water using one or twoway coupling. Is possible apply icoLagrangianFoam to acess this kind of flow? How I download the newest version of the solver on of1.6? Do you know any tutorial? Thank's in advance.

Hello,
is there a version of icoLagrangianFoam that is compatible with OpenFOAM v7? Or any alternative that is only doing the additional particle tracking?
