how to save the hardcopy in every time step
 
I'm doing a 2-stroke engine simulation,before the process run,I creat a view for vector of velocity magnitude,and I want to save the view after every time step.
could anyone tell me how to do it
thanks in advance!

maybe it requires to use execute commands,but I don't know how to write the macro.could anyone tell me how to do it?or any tutorial for write macro in execute commands windows.
thanks in advance!

go to generating the images

I remembered I had problems If you have multiple display-windows.
So you need to activate the one you are using for the pictures.
This can be done by adding this line prior to the other in solve/execute:
> dis set-w 0
where 0 is the number of the window you are using

hi max:
thank you very much for your reply.
I visit the website you give me,read through it and have a idea about how to do my work.
another question,the article says:"Since you will be entering text commands in this panel, it is a good idea for you to practice with the text interface first to make sure that you issue the commands correctly".for example I save a new view for velocity vector or the pathline of air entering from the inlet.how can I write the text commands?or how to practice myself?
thanks in advance!

on 6.3 it was possible to navigate in the pull down menus with the mouse.
But you could also do the same by entering names of sections in the script window (where you get transcripts from fluent).
For instance by typing "grid"
you are in the grid section.
Then a "check", call the check
this is Text User Interface (TUI).

So before entering your macros in solve/execute, make sur your commands run well, by testing them.

small correction
 
wow..that works..
except that i am using fluent v6.3 and in it, the executable command is "display contour" and not "display contours"..
"contour" is what that is available in the TUI..

:)

I typing "grid" in the text interface,then check.fluent check my grid.but it says "invalid command" after typing define.shown in picture 1,what can I do.
then,could you tell me how to check my command?

I don't remember but I think you are trying to switch to another section.
so try typing "/define"

yeah,I do it,thank you!
by the way,if I want save the hardcopy every time step for velocity,is the command"disp vector velo-mag 0 10"right?how to write the command I need is the basic problem.

what you mentionned is just for the display.
you need, to write as hard-copy:
> dis h-c name_your_picture_%t.jpg

I run the process,the windows show nothing.shown in picture
and my command is shown
I think the command is not right.
any idea?

the black window you are showing is affected with number 1.
That is the trouble I had...
Befor you run the macros, I would open the right window, display the geometry, zoom and adapt it as you wish for your pictures.
Then don't close the window, and run the iterations (with macros)
Once you will uinderstand, it will be easier (but admit it is fuzzy)

yubaibai88 May 27, 2010 09:28

hi,it still don't work.
but I try to write the command as "disp contour velo-mag",it works
maybe something is wrong with the command?
