remove particle

im going to implement a function in icoLagrangianFoam, and i use basicKinematicCloud, i want to delete a particle from specific zone in computational domain. for now i can return access to particle and mark it, but i dont know how to remove it.

deleteParticle or move functions are a part of Cloud class, i can not understand how i can access to Cloud.H from basicKinematicCloud object?

i continue this post, it can be achieve with following piece of code:

Quote:

kinematicCloud.deleteParticle(p);

but after it deletes the first particle, it error in second one, the error line is:

Hi Nima,
would you please explain how did you managed to solve the problem?

following syntax:

Code:

typedef typename Foam::KinematicParcel<Foam::particle> parcelType ;



forAllIter( basicNewKinematicCloud , kinematicCloud, iter)

{

    parcelType& p = iter(); //paticle

   kinematicCloud.deleteParticle(p);

}

hi, could you please tell me where you write those codes?

you can add it to your Lagrangian solver and recompile the solver
