[MITgcm-support] Plume on a slope time step

in the data namelist file

 &PARM01
 globalFiles=.FALSE.,
 useSingleCpuIO=.TRUE.,

to 'combine' the tiled output.


check dumpFreq, looks like it must be set to 20 s/timestep 300 timestep = 6000s. the example below has the dump every 10 mins.


 &PARM03
 dumpFreq    = 600.0,

> Hi, I'm a little confused with the time step of the plume on a slope experiment. In the  data file there is a line which sets the time step equal to 20s (deltaT=20.0). There is another line which sets total number of time steps, and I made it equal to 12000 (nTimesSteps=12000). When I ran the experiment I get 40 output files of horizontal velocity and other variables ordered like this:
