Hello !
I want to add the Brownian force to icouncoupledkinematic... due to the nanocale of particles. I add BrowniaMotion to particles forces at constant/kinematicCloudproperties but the force is not valid. Then i add Brownianforce.H to lagrangian/intermediate/lninclude/makeParcelForces.H. But there are errors in the process of compilation. I solve many of them except one. lnInclude/BrownianMotionForce.C:179:28: error: ‘const parcelType’ has no member named ‘Tc’ How can make icouncoupled... to read both makeparcelforces.H and makeThermoparcelforces.H Can somebody help ? Thanks in advance. |

The problem solved but it seems that the model of brownian force does not work properly .
The velocity of the spheres is very high. Any help will be greatly appreciated. Quote:

Solved !
The dt that used by the code is not the timestep and the boltzmann constant is in eVK^-1 but we must set it in J/K Quote:

Hi, Evangelos.
I also want to add some type of force to the icoUncoupledKinematicParcelFoam. Is that possible for you to share your code here so that more foamers could benefit when facing the same problem? thank you in advance! Best, Karekle |

Hi all,
Do you solve this problem? can you please share your code? I met the same problem. How you add the brownian into icouncoupledkinematicFoam or DPMFoam |
