Video from case and data files

girino · February 25, 2010, 06:55

Hi all,
I'm working on an unsteady simulation with XP. I've saved my "Case and data" files for each second, my time step is 10e-3, so I have about 300 "Case and data" files. Totally I have about 300 seconds. How can I make an animation of these 300 seconds? Should I save for each "case and data" file a .jpeg and use a program to assemble all those images in a video?

Thank you very much

Hi,

As I know for the unsteady simulation you should make mpeg video file as follows:
Solve/animate/define/

Hope to share experience on CFD

Regards,

Thanh

Calculation activities for each time step

e.g:

/di/set/picture/driver jpeg /di/set/cont/surface A () /di/view/restore-view B /di/cont velocity 0 1 /di/save-picture "/home/picture.jpg"

That is the procedure if you have only one "case and data" file. I want assemble 300 different "case and data" files. Thanks for reply Thanh.

@hubiloo
What does that piece of code do? How can I assemble?

with calculation activities --> create/edit execute commands you can define different kinds of activities for each time step or iteration...

The given code is a text command (check out the help), which is execute each time step...

I do not want iterate, I want make an animation. Can you do that with only case and data files?

Maybe there is a better way, but in my opinion you have to calculate again...

with /display/save-picture/"folder/file.jpg" you can take pictures of every time step. After your simulation, put all pictures to a movie together.

Ok, thanks.

Hi Hubidoo

but display menu does not have "save pictures" what do you mean?

i tried to do it from execute commands in solve menu but i could not do it correctly,
please help me, i wanna save window of contour each several time step.

thanks in advance

Use Tecplot.... there you can make good animation
