How to write XY-plot with journal
 
Hi !

I can't find the text commands to write a solution plot in a file.

I created an iso surface, then ploted it on screen, but I would like to write it down in a file (I've got a lot of "plot" to write...). Here is what i've already written :

surface iso-s y-co y=0.005 () () 0.005 ()

plot solution pressure () y=0.005 ()

Thanks for your help !

Depending on your coordinate system this should work :

plot plot yes plotname n n n pressure y 1 0 0 ()

Instead of () you can write the Id-number of your face/line

Great, it works.

What does means "order points" ? With and without this, I have 2 different output files :

"0.00975 - 70956.9" for "no order point"

"0.01 - 72562.1" for yes

*

Something else... In the output file, the first coordinate is the max, and the last one is the min. Do you know how to invert this ? (minimum valu firts, anf then the biggest)

Thanks !

Inot sure about that `order points I did the comand for printing a temperaturplot over a line there was no difference. Maybe someone else can help. To invert the coordinates write -1 instead of 1

"-1 instead of 1"... that's such an evidence... ! ;-)

Thanks !

I just made a check with a face-plot in my calculation and I think the difference between `order - yes and `no is that with yes the results are sorted ( in the dictionary its also said ordered can be the same as sorted ). But I have another question to you : If you plot out results of a face how can you analyse them with just one coordinate?

Re: How to write XY-plot with journal
 
What I'm trying to analyze is the shock wave shape (an 'N' shaped wave in fact).

To be serious I should check the pressure profile perpendicularly to the shock. But I do it horiontally... which gaves the same result for intensity (but not the same for the shock wave duration).

N-Shaped wave : www.arl.army.mil/acoustics/jasa98.pdf

Am I clear enough ??

(are you french ??)

Im not familiar with shock wave calculation. My primary works are heattransfer calculations and flow of liquid metals. but Ill have a look at the paper you sent me. Thanks

Hope this will help you to see what I'm dealing with :)

Looks pretty cool (I guess much better if colored ) Where are you from?

Dear Cyril
I want to create 5 iso-surfaces on a 3D 0.003 m long channel along x-axis. I read the manual and tried accordingly but could not succeed. Could you help me writing a jounal file to produce the surfaces. Thank in advance.

regards

Replace your iso-surface name, from-surf and pos with your own data.

Code:

/surface/iso-surface x-coordinate name from-surf () () pos ()
