This is another video about model editing.
Simulation of Rigid Ball Impact on Aluminium Oxide.
What is done in this video:
The parts in the original file was edited. The parts we recreated to match the actual experimental values.
This video is good if you already have a file and want to modify the part. Say, you have a model for vehicle which you download online, and you want to modify the bumper shape and see the effects.
Sorry for the poor video, this was not meant to be online tutorial. I just recorded what I did for some final year project.
