The DPM model doesn't see the free surface as such, it sees the cell fluid properties. So, unless you want to start some (very complex) UDF coding your particles will behave exactly as the flow in that cell forces them too. 

The flpj file is a way for Fluent to keep data files together for a transient run. Can you check disc/file access permissions as it should work fine.Â
