Hi Guys/ Gals,
Thanks for your help with my last query and the simulation works fine... my problem now is trying to get the animation to work; I set a save time interval to be the same as the time step intervals (5 iterations per time step).
However, when the simulation is finished and I select the 'animation' tab there are no steps to select to swtup the video.
Any idea what I am doing wrong and how I can rectify it will be greatly appreciated.
Cheers,
David
Hi,
I think we may need to change how you are saving out timesteps.
Could you detail what your timestep size is, what your stop time/number of iterations to run for are?
We typically recommend saving out 20-30 or so timesteps per run, so that we do not produce a file size that is too large to re-open.
Knowing the above will help provide a more accurate recommendation.
Right now it sounds like you are saving every step, which may not work so well.
Hello David,
Could you not save out 30-40 results on just the last cycle? Seeing as they should all be identical.
I should have asked this too, why are you looking to save out intermediate results? Are there specific areas of interest?
Will 15-20 results per revolution for the last cycle provide you with enough information?
Cheers,
Jon
OK, I suggest we do 2 things:
1) Run a quick test saving out every step and run for just a few iterations, just to test all is working OK
2) Can you post up the table you are using to save out results for us to verify?
Cheers!

Hi Jon,
I've had a play around but now I keep getting a message saying "analysis stopped unexpectedly - please send to technical support".
I have tried attaching a copy of the cfz file for you to have a look at if you get a chance, it should show my tables as well, but it's too large (5GB when limit is 1.5GB); would it be possible for you to send me a direct email so I can send you the file?
Thanks for all your help I really appreciate it.
Cheers,
David
That is quite a large file, really 5GB? Can you save out just the support_cfz file?
Happy to setup a Dropbox folder, but please don't send me a 5GB file as it will fill up my allowance 🙂
Could you share just a screenshot of the table?
Also, you may just have a corrupt folder, perhaps try in a new one?
Sorry seems like I'd clicked the whole folder instead of just the cfz file (only 21lb)
Here it is below.
Cheers,
David
Hi Jon/ Anyone else who can help,
I've managed to get an animation of the simulation be redoing the whole assembly, except the inlet valves, as one piece; this appears to have worked.
Now I've got the visual representation, how would I go about finding values at the 4 outlets at specific times in relation to valves opening; is it a case of setting up a results table which records the values at those specific times or is it more complex than that?
Any help greatly appreciated.
Cheers,
David
Hi David,
This really depends if all 4 outlets are in-line or not.
I am assuming that they are so you wil need to add a cut-plane and use the bulk calculator to give you the pressure across each of the outlets. Then move to a different time and repeat.
Hoepfully you do not need to look at too many time intervals.
Happy to hear from anyone else if they can think of a better way 🙂
Hi,
If I remember correctly, when you set the animation to play, and then use the plane bulk calculator to calculate the values, Sim CFD will print out the values for all the time steps played. With this, you can save the values in a csv file and sort them out in excel. It is not an ideal workflow but it should still be practical though.
