I created a new particle force which it's in

src/lagrangian/intermediate/submodels/Kinematic/ParticleForces

and works well. Also

src/lagrangian/intermediate/parcels/include/makeThermoParcelForces.H

is modified.
Here's my question: is there any way to do this externally. In some scenarios, for example HPC, I don't have write permission to the system version and have to compile my own OpenFOAM in order to add particle forces.

Yes, it is quite forward. Define your force as you did in a new folder and create a novel makeNovelThermoParcelForces.H and only include your new force in that header. Use a different name for the macro, since it is already defined in the makeThermoParcelForces.H. Finally, you need to create a new file, for instance makeNovelThermoParcelSubmodels.C:

#include "basicThermoCloud.H"
#include "makeNovelThermoParcelForces.H"
 makeNovelThermoParcelForces(basicThermoCloud); // name of the macro defined in makeNovelThermoParcelForces.H

For a better overview, try to keep the same structure as in the your OF/src. Then, change your Make/file and Make/options. Of course, you have to include the lagrangian intermediate library in your Make/options in order to make it work. You can then either link the library at runtime in your controlDict or add it to your specific application Make/options.

Good luck. RP

Hello,

Sorry I forgot about this problem when I was thinking about it. Now I really need to implement it and I followed your instructions. However my particle force is not available in the hash table. Would you mind provide a minimum working example? Thanks.
