can't find my results

Absolute newbie to Autodesk CFD so sorry about the very basic response. 

 

I ran an analysis last night successfully.  It generated results which i was in the middle of analyzing. I had hit "save" in the menu bar.  Unfortunately Autodesk crashed - and when it returned I reloaded my study but there is no evidence of any results. There is a .res file but it is very small and it doesn't share a name with my study.  

 

Is there any description in the documentation of where and how results are saved?

 

Furthermore is there a description of how the various files and scenarios are related? 


Sorry this question is so basic.  

 

Thank you!

Hi @davef_dci,

 

Are you opening the design study through the CFD UI or via windows explorer?

 

Thanks,

David

David,

 

Thanks for your note!

 

I am opening it through the CFD UI. I'm starting to wonder if this is a result of CFD having crashed while I was viewing my results?  Sorry my questions are so basic.  When I hit the "save" icon in the UI, does that save both the model and the results or do I need to do something different to save results?

 

Is there a description in the documentation of the relationship between the CAD model, various studies and the results? 

 

Here is a link to my study. 

 

FYI, I am just learning and evaluating the software so this study isn't that critical. I don't lose anything if I can't find the results - I just want to learn the principles. Thanks for your help.

Looks like there are some results which might be recoverable. Please run the scenario for 0 iterations continuing from iteration 100.

 

Results are mostly saved automatically, just make sure you click yes to save design when closing CFD to be sure.

 

Also make sure you are opening a .cfdst file and not a .cfz file. The cfz file will create a blank design study with the same setup as your solved design study.

 

Does that help?

 

Thanks,

David

David,

 

Alas, when I try to solve I'm unable to "continue from" 100 - the only option that shows up there is 0.

 

I'll re-run. It's good to know that I don't have to do anything special to save the analysis.  I wonder what went wrong. 

I'll try again and see if it works this time.

David,

 

I re-ran the analysis again and the same thing happened.  I ran the analysis for 300 iterations. Did a bit of analysis, saved the file and closed out. When I open up the cfdst file there are no results. 

 

 

I am running a trial license and have 29 days left on the evaluation period.  Does the trial license not allow you to save any results or something else going on here????

 

I can send you a link to files if that would help. It's the same model as last time re-run. 

 

Thanks!

Hi @davef_dci,

 

Please send me a share file (.cfz)  and I will run it from my end. If it runs without issues here then you likely have read/write issues and may need to look at your firewall/antivirus settings. But we will get to that later!

 

All the best,

David

Thanks David - I have the same issue with the model linked on my question regarding wall forces. There is a link to the study on that question. Would it be possible to use that link?

 

I really appreciate your assistance.  This is a really cool tool but i have a lot to learn.

That link only contains the design folder and not the complete study. Upload a share file (.cfz). Or everything from the folder one step above the design folder.

 

Thanks, 

David

David,

 

I rebooted my computer, created and re-ran a new study and I am now able to retrieve the results after closing and re-opening the files.  I think the problem must have been on my end when CFD crashed on my original model and perhaps corrupted that file? I'm sorry to have bothered you with this - I was so new to CFD that I wasn't even clear if there was some special way I was to be saving the model. I think it turns out that I, unfortunately, had a one-time issue associated with a crash that happened to occur before I knew how things were supposed to be saved. 

Unless it re-appears I think this issue is solved or at least can be by having me reboot if there is any sort of crash of CFD. Now that I understand that the results are supposed to be saved with a file save I know what the look for.

 

Sorry to have distracted you and thanks for your help.

 

I still have a question posed elsewhere on the forum regarding Wall forces. If you have any insights into that I'd be grateful.  

 

Dave.

No problem. Enjoy simulating! I will have a look at your wall forces thread.

 

All the best,
