Hi,

Just as Fluent lets to interpolate solution data to a new mesh (which I know only applies to cell data) is it possible to do the same with my coal particles? I want to take my full solution (both Eulerian and Lagrangian phases) from mesh1 and interpolate it to mesh2. Domain extents and boundary conditions remain the same, mesh2 is only a refined version of mesh1.

If they're transient particles you can write the summary file out and use that as an injection file. You may need to fix headers etc but it's mostly the same format.

Thank you for the advice
However, according to:
23.3.12. Point Properties for File Injections
I was wondering if only these 13 variables are allowed? My discrete phase are combusting coal particles, which may require some more inputs

Do you know if its possible to add some more columns to the injection file (starting from Col 14... to Col 21 ? ) My ultimate goal after interpolation to mesh2 is to continue my simulation exactly at the point where the results on mesh1 stopped (including all previous chemical and reactive features for both Eulerian & Lagrangian phases)

[Rob]

I've checked but you may need to re-run from the start or forget the extra bits in the particles if you move them over. You may get somewhere using the above and the interpolation file then waiting for the solution to re-establish itself.

Thank you
For now I used the interpolation and the injection-file, although I needed to decrease the number of parcels (from 16M to 8M , Fluent was leading to CORTEX FATAL ERRORS at the very beginning).
Also, for other users trying to do the same: I found convenient to reset the flow time to 0 s (rpsetvar 'flow-time 0) and to manually set columns 12 & 13 of the injection-file to 0.0000e+00.

You're welcome. Thanks , for posting a solution
