T2well output files

Hello T2well users;

I have just started using the code. I run a case with only a well model (reservoir represented solely by the last grid block at the bottom). All the 5 output files FOFT, COFT (as planned for in input file) in addition to DOFT, FFlow and Fstatus were produced. Only DOFT seemed to have only nil values in its 3rd and 4th coulmn (out of 4).  In another attempt I included a reservoir section using the same PARAM input as before. While FOFT and COFT showed sensible results, FFlow and FStatus contained only the titles, no data. Any experiences or advise?

Thanks
