I can play the animation in fluent. When I write it to MPEG file, I got the following error message

CX_Hardcopy_Window: error opening PPM file .\pressure_1_0000.ppm. CX_Hardcopy_Window: error opening PPM file .\pressure_1_0001.ppm. CX_Hardcopy_Window: error opening PPM file .\pressure_1_0002.ppm. CX_Hardcopy_Window: error opening PPM file .\pressure_1_0003.ppm. CX_Hardcopy_Window: error opening PPM file .\pressure_1_0004.ppm. ...

cxa file

AnimationSequence1.0 NAME: .\pressure WINID: 0 STORAGE: 2 FRAMES: 200 Frame 0 2 pressure_0000.hmf 0 Frame 1 2 pressure_0001.hmf 0 ...

Thanks.

What's your OS? Linux/Unix or Windows? If Linux, it often simply doesn't work, guys from the support told me it is a bug. You can save your frames as jpgs or tiffs one by one with a journal and then join them with an external application. If Windows, a friend of mine had a similar problem some time ago solved moving a configuration file, but I don't remember any detail...sorry.

...having this problem with exactly the same error (Linux Suse 10), I am looking for some external software for completing the particular JPGs into the one animation (AVI or GIF). Does anyone know any handsome animator for Linux?

I'm using windows. Is there any software that can open hmf files directly? I'm not familiar with journal. Would you mind giving a simple example?

Thanks a lot.

I use ImageMagic (freeware) under linux to create gif-animations. First you have to convert jpg to gif and then merge the gif-pictures into a single gif animation. Here's the site: http://www.imagemagick.org and some more examples of the usage: http://www.cit.gu.edu.au/~anthony/graphics/imagick6

I searched once on the web for a .hmf viewer for free, but I didn't find anything, if you will be luckier, please let me know...here a simple example of a jou that saves ps files with a little annotation from hmf files written during a transient simulation. I think it doesn't need any comment, it just push buttons instead of me...

(define j 0.02)

(cx-annotate '(1.29904 -0.479065 -0.050389) '(1.29904 -0.479065 -0.050389) "<*" (format #f "t=~ds" j))

(cx-gui-do cx-activate-item "Graphics Hardcopy*PanelButtons*PushButton1(OK)") (cx-gui-do cx-set-text-entry "Select File*FilterText" "*.ps") (cx-gui-do cx-activate-item "Select File*Apply") (cx-gui-do cx-set-text-entry "Select File*Text" "000.ps") (cx-gui-do cx-activate-item "Select File*OK")

(do ((i 1 (+ i 1))) ((= i 212))

(cx-gui-do cx-activate-item "Playback*Frame1(Playback)*ButtonBox6*PushButton5( step_forward)")

(set! j (+ 0.02 (* 0.02 i))) (cx-annotate '(1.29904 -0.479065 -0.050389) '(1.29904 -0.479065 -0.050389) "<*" (format #f "t=~ds" j))

(cx-gui-do cx-activate-item "Graphics Hardcopy*PanelButtons*PushButton1(OK)") (cx-gui-do cx-set-text-entry "Select File*FilterText" "*.ps") (cx-gui-do cx-activate-item "Select File*Apply") (cx-gui-do cx-set-text-entry "Select File*Text" (format #f "~03d.ps" i)) (cx-gui-do cx-activate-item "Select File*OK")

)

For creating animation under windows, I like makeavi very much http://makeavi.sourceforge.net/

Hope this helps

Edi.

In what format did you save when you defined the animation sequence? It should be PPM format.

Do you ran any batch file in your working directory or simply write commands from bash? If first, i hope you wouldn't get annoyed if i ask for that batch file providing converting+merging JPEGs into one GIF. That helps me save time.. Thank You!

Hardcopying jpg-pictures from fluent is done by a linux script. converting jpg to gif and merging them to a single gif animation is done by two shell comands ("mogrify" and "convert") provided by Imagemagic.

It should be PPM file. Then we can write the animation file.

Thank you. I found out that the problem occurs when I close fluent and reload the animation sequence. If I write MPEG immediately after recording, there is no such error.
