Dear all,

I have used the following parameter file (shown at the end of this message)
to run Gadget4.
But as soon as I run the simulation it ends and says "Final time reached"
and it does not
create any snapshots:

Final time=1.26 reached. Simulation ends.
RESTART: Writing restart files.
RESTART: Backing up restart files...
RESTART: done renaming pre-existing restart files to bak files.
RESTART: Writing restart files group #1 out of 4...
RESTART: Writing restart files group #2 out of 4...
RESTART: Writing restart files group #3 out of 4...
RESTART: Writing restart files group #4 out of 4...
RESTART: done. load/save took 0.00217194 sec, total size 0.0659027 MB,
corresponds to effective I/O rate of 30.3428 MB/sec
endrun called, calling MPI_Finalize()
bye!

I would be grateful for any insight into this problem.
