Note1: when the original cas is read in the new releases, the time step is no more a round number, 1e-3s, but it gains that additional decimals....I am assuming that it does not affect the computation

Note 2: the injection file is now (just to be sure I am not messing up here somewhere):

Instead, I missed what you said about "You can use the option STart fol-time in File" to start injection after certain time elapsed: the last column in the injection file will then be used".

Do you mean the "Start flow-time in file [s]" options in the "point properties" dialog box? if I do not use this option "the last column in the injection file" is not used?

thanks for your help

*13th column*, as reported in the user guide). Up to now, that is the test that I reported before, I was using the 2019R1 release. I have now used also the 2019R3 and 2021R1 releases: actually it seems to work, but it is skipping the first interval (from flow-time 0 to flow-time 5e-03[s]). Also, the injection time, that should be at flow-time= 3e-3[s] (and all the other time-steps according to the 5e-03s repetition interval, so 8e-03[s],13e-03[s],18e-03[s],etc.), sometime occurs in the next time-step:[...
