While pace has slowed on new Mobile Multibody Dynamics releases since MOMDYN 2.0 on Android, rest assured, the show goes on. There will be a version 2.0 for iOS, using native SwiftUI and SceneKit ... soon. in the meantime, I've done some cool stuff like this Euler angle rotation code:

Double Pendulum Simulation Video
Check out the brand new video on our YouTube page showing a simulation of a double pendulum using two rigid links. The kinematics are defined using two revolute joints for rotation, and rigid translations to define the centers of rotation. Double pendulums are famous for being chaotic, a small change in initial conditions lead to a large change in response. Here, we show this by gradually increasing the initial angle, where the pendulum motion starts out as fairly simple and repeated oscillation, it becomes more and more disorderly as the initial angle increases, with the second link eventually doing complete flips relative to the first link. Learn to build a model like the animation below, and video after the jump.

Ship It! Version 2.0 is rolling out, and new vibration tutorial
As I've mentioned in the last two posts, MOMDYN is getting its biggest upgrade yet, with version 2.0 for Android implementing a fully rebuilt, native interface. We will be rolling out to all new and existing users in the next week. In the meantime, check out this tutorial on Youtube to create a mass-spring-damper system, typical of vibration analysis (after the jump).

Version 2.0 beta test is live for Android users
As I posted a couple months ago, I have been hard at work re-building the Android version of Mobile Multibody Dynamics. Well, I'm happy to say that the update is just about 98% done, and ready to go for beta testers! If you are an Android user, you can opt into the beta test by visiting https://play.google.com/apps/testing/com.badeyedea.momdyn. Below image is from the updated tutorial video for a simple pendulum, and you can catch a Youtube video showing how to create this model after the jump.
