hadian is on a distinguished road
i want to create a small journal file to
1- read case and data
2-initialize a surface (which is my air inlet and the name is air_inlet)
3- do the iteration
4- save the case and data
5- exit
here is my journal file. but it does not work well and give me an error in initialization part.

/file/read-case-data /home/hadian/1.cas
/solve/initialize/compute-defaults/air_inlet
/solve/iterate 10
/file/write-case-data /home/hadian/2
yes
/exit yes
/exit
/quit

blackmask will become famous soon enough
It seems that the command for 2 is missing, see below. I have a vague impression that FLUENT will initialize the flow automatically upon iteration. But you should try to manually add this line to check whether it makes any difference.

ONE LINE MISSING HERE

yes

it seems that the command "/solve/initialize/compute-defaults/air_inlet" does not initialize on air_inlet surface. i do not know if the command is correct it something should be add to it!!!

/solve/initialize/compute-defaults/velocity-inlet air_inlet
if you name your inlet boundary "air_inlet"

this is the result:
> /solve/initialize/compute-defaults air_inlet
invalid command [air_inlet]

so there is something wrong!
