@Tevonic, Codename Lisa, and Ronhjones: I would like to upload similar pictures I created
But I don't understand the free-use-copyright of this image. The file Finte-Element-model is created by the National Crash Analysis Center (NCAC), the models were moved to https://www.nhtsa.gov/crash-simulation-vehicle-models and therefore are Wikipedia:Public_domain#U.S._government_works?

- Since the image was set up as non-free and the only source was the user, it has now been reduced to be NFCC compliant. You may well be correct that it PD - but you have shown that the original picture was on gwu.edu - so that means that it might still be copyright protected as the creator may not be a government employee. It's a bit of a grey area. I suggest post a question at c:Commons:Village pump/Copyright - because if it is PD then the image will get tagged for a commons move, so best to check before that happens.

- Sorry the image was created by the user, but the image is a picture of a finite Element-Model which is created by the National Crash Analysis Center (the model, but not the picture). I will ask at c:Commons:Village pump/Copyright for further help. Maybe the @Tevonic: restricted the use of his screenshot of the NCAC-Model. — Johannes Kalliauer - contrib. 16:32, 4 November 2017 (UTC)
- It would be a good idea to ask for clarification, but I suspect this falls under fair use as a screenshot of a video game would. Their copyright I assume is made to protect the actual model, not the use and screenshots depicting the model. Plenty of videos and pictures of their models exist online. If someone more knowledgeable could clarify that would be ideal of course. Tevonic (talk) 05:14, 7 November 2017 (UTC)
@Tevonic: Please check the inputfile of the FE-model (Main.dyn) the Autors are written into the file. NCAC just publishes FE-models, but they are not the authors. — Johannes Kalliauer - contrib. 18:33, 7 November 2017 (UTC) @Tevonic: Next time be more careful before reverting edits. — Johannes Kalliauer - contrib. 18:33, 7 November 2017 (UTC)
- @JoKalliauer: Where are you getting this "main.dyn" file? I uploaded the image from a model I created myself using the NCAC car model. When false authorship information is placed on work I contributed, I remove. Also note that the model you provided as authorship doesn't even match the speed referenced in my model, they are both different models. To verify I went back and found all the input models and these have no authorship information. Anyone can easily take the NCAC model and place it in pre post to create a model, collide cars, etc. with ease. Tevonic (talk) 06:02, 8 November 2017 (UTC)
- @JoKalliauer: Here is a reference that states the geo metro car model: https://books.google.com/books?id=P820ROOH0psC&pg=PA34&lpg=PA34&dq=National+Crash+Analysis+Center+(NCAC)+geo+metro&source=bl&ots=NYLGcH6VkB&sig=cg55gj7rJozmGPzCTUnGyaxGV-A&hl=en&sa=X&ved=0ahUKEwjYpPTcqa7XAhWITCYKHRJuDJEQ6AEIQzAF#v=onepage&q=National%20Crash%20Analysis%20Center%20(NCAC)%20geo%20metro&f=false Tevonic (talk) 06:23, 8 November 2017 (UTC)
- Meant to say this reference shows NCAC developed the car model. The simulation input file was setup by myself using this model. The authorship information therefore appears to be completely erroneous, unless you can clarify where you got it and how it pertains to this model. Tevonic (talk) 06:26, 8 November 2017 (UTC)
- Sorry you are absolutely right. It looks idential to this model: Picture Model
- This slighltly changed model was "creaded" by the Politecnico di Milano as written in my thesis (german).
- But still the authors are unknown.
