Differential constraints in car dynamics. How the ESP car system works?

This post explains how differential constraints that are widely used in CAD/CAM can be combined with classical mechanics to produce car ESP system that will be manufactured serially and mounted in modern vehicles. Main problems of constraints and conditions of ESP system are explained.


Piston animation using Hamiltonian mechanics

This post presents piston move animation according to Hamilton mechanics with full real-life physics support solved using C# and WPF. An in-depth derivation of motion equation has been published to help understanding of Hamiliton mechanics. This is tutorial is helpful start-on in various mechanical simulation. Full source code, executable and explanatory pictures are downloadable. As a result easy to use educational animation has been produced that facilitates understanding of piston work and movement.


How to get properties of points in NX Open

I received an ask for a help to get the properties of a points. The post explains how to get properties of NX points objects and work with them. The post presents a real world CFD problem with a solution.
