kraken is on a distinguished road
I am using openfoam to calculate the flow field of a rectangular section channel with a cage in it and try to analysis the influence of the blockage on particles transport in the cage.

I plan to inject particles in the cage, which means only part of flow field is what I exactly need, thus I used decomposePar to divide the cage into processor1 in order to reduce calculation time and after steady state I created a new case inwhich 0/,constant/ were from processor1, I got correct U,p... and polymesh, which all perfomed well in paraview. I also redefined the boundaries by creatPatch.

But when running the new case with particleFoam I always get an error "Not implemented...FOAM aborting". I think maybe BC in 0/ causes this error but don't know how to fix it.

So how to fix this error or maybe there is more appropriate methods to achieve this?

My openfoam is v10, ubuntu 22.04LTS, porousSimpleFoam for flow field, particleFoam for particles

My English is not very well, thank you for reading this and any help would be really appreciated!
