how to write IOField solid particle positions
 

Hello,

I am using the solid particle library and have looked at solidParticleFoam. I saw 'positions', 'd' and 'U' in the directory of 'lagragian/defaultCloud' in the tutorial case. I am dealing with thousands of particles, just wondering how could I generate the 'positions' file for the particles?

I think the particle position belongs to IOField<vector>, but how can I determine the positions and write them into a file using OpenFOAM? Any suggestions would be really appreciated.

Thanks a lot in advance.

Best Wishes,
Sophie
