In this scene I build three models and make them vibrate or collapse.
This link opens a video in which I make a comparison between the algodoo and reality.
I use three real models and three similar models on Algodoo.
Wall, arch and beam.
The test consists in making the models vibrate and collapse on Algodoo and do the same thing in reality, mounting the real models on a vibrating wooden plate.
So I compare the results to see the similarities.
Do you want to see the TEST?
Watch the video!!
Thank you!
Do you want to see more?
Many other videos?
Check out this playlist !!!
THANK YOU!!
1. Arch Example: Algodoo bricks above arch are longer than real bricks.
2. Beam example: Algodoo shaking frequency is twice real life shaking frequency.
3. The file size is 5,517 KB. The size can be reduced substantially (to 463 KB in my test) by doing the following:
Extract the zipped texture files in ALGODOO reality TEST.phz to Algodoo\textures.
Save ALGODOO reality TEST.phz as a ALGODOO reality TEST_01.phn.
Compress the added Algodoo\textures\images to .jpg files.
Open ALGODOO reality TEST_01.phn with a text editor.
Replace ".png" with ".jpg".
Save ALGODOO reality TEST_01.phn in the text editor.
Open ALGODOO reality TEST_01.phn with Algodoo.
Save ALGODOO reality TEST_01.phn as ALGODOO reality TEST_01.phz.
Delete all the recently added images in Algodoo\textures.
The process above typically takes me less than 5 minutes and can reduce the file size substantially.
In addition to s_noonan's observations, I wanted to point out that the shaking frequency and amplitude in the real-world examples look somewhat chaotic, which more represents a seismic event than just a single frequency and amplitude which is what you employ in your Algodoo scene. In other words, the real-world examples look much more violent. Also, the real-world examples look like they are not only shaking from side-to-side, but also up-and-down.
@s_noonan
Thank you very much!
I replaced the .png images with .jpg.
I will always use .jpg images!
Thanks for your advice!
Yes, it is true, the dimensions are not perfectly the same.
The vibration speeds are different but the focus, in my opinion, is on how the structure collapses.
In the case of the arch, the similarity is clear, the arches collapse in a very similar way.

Thanks for the comment!
The plate in the real world vibrates only horizontally.
I made a video with the smartphone fixed on the vibrating plate.
It seems that up and down also moves, but it is only an optical effect and probably the not perfect fixing of the smartphone.
The vibrations are certainly greater than in the Algodoo environment which is perfectly controllable.
Also, in order not to collapse everything forward, I added a small plexiglass plate in front of the bricks.
An attempt to move the specimen only in the X and Y axes.
I agree, Algodoo does look like the real thing. Nice concept. I think this may be the first scene where a real model and Algodoo are shown side by side. What application do you use for video editing?
Q: Do you like video editing too?
A: I don't know, because I haven't really done any. I did like the part of the video where the Algodoo model overlaid the real world example.
