journal file:write-case-data

Lilly · July 18, 2012, 06:11

Dear all,

I want to start a transient Fluent-simulation as a batch job and therefore wrote a journal file.

/file/read-case-data/ D:\TestFile.cas
/solve/set/time-step 0.01
/q
/solve/dual-time-iterate 50 200
/q
/file/write-case-data/ D:\TestFileComplete.cas

But for any reason I cannot make fluent save the final case and data files as denoted in the last lines of my journal file. I don't get any error message, but fluent just stops after the calculation. I already tried a lot of variations of the last lines.
Does anybody have an idea?
Thanks a million for all ideas and help!
Lilly

It won't help you a lot but I just tried your last command line in Fluent and it worked fine for me.
Are you sure you have the writing rights on your D:\ directory?

don't bother telling fluent where to put the file, it will put it in the working directory if you just give it a file name, also needs quotes, this should work (see below), if not then try making your working directory something other than the root of D:\ say D:\Test\ root permissions can sometimes cause problems.

/file/write-case-data "solution.cas.gz"

I also write a journal file. It can read the case- and the dat-data but when it wants to initialize the calculation it stops. Can someone help me?

; Read case file
rc propellerviskosimeterFluent.cas
rd propellerviskosimeterFluent.dat
; Initialize the solution
;/solve/initialize/initialize-flow
; Calculate 50 iterations
it 50
; Write data file
wd example50.dat
; Calculate another 50 iterations
it 50
; Write another data file
wd example100.dat
; Exit FLUENT
exit
yes

Greetings

Hi manuels,
in the journal you posted here I see the semicolon before the command:

;/solve/initialize/initialize-flow

maybe you have forgotten to cancel it

Hello
I am also having this same problem. Basically, I have one script in which I just change the name of the case and data files. It works well for 2 other simulations but on one sim it doesn't write the data file. The solution converges and closes. JUst does not write
