Dear all, I am trying to get Fluent run as a batch process on a SGI machine. However, my journal file is not working. Can anyone help me figure out the problem with my journal file and batch script? Also can someone post or send a sample journal file? I copied the batch script and journal file below?

Thank you all in advance. ahmet

I'm not sure about the bc settings in your journal file - I would write

/define/boundary-conditions/velocity-inlet 5ft-inlet n n y y n 6.80 y y n 10.764263 n 10.764263

Thanks PAD, that worked just perfect.

However, I couldn't figure out how to enter scalar when exporting the data to an ascii file. I tried something like following but didn't work. I couldn't find it on the manual either. Can anyone help me with this? Thanksss!!! ahmet

file/export/ascii 6-15a-060731 '(point-8 point-9 point-10) n n ????pressure pressure-coefficient velocity-magnitude???? n

Dear ahmet u can do all u need to perform batch operation as follow 1-open a new journal file 2-from writting the commands like that file read-case "c:\mesh1.mesh"

and see the response of the program u can learn yourself simply 3-close the journal and select what u need to do than save that in a new journal

i hope this useful
