RLC simulation in Matlab using Euler method

Here is a comparison between the Implicit Euler Method and the Explicit Euler method on a given RLC circuit. We will be using the two methods stated above to model the variation of the current in the circuitry below. RLC simulation in Matlab We consider the capacitor

Free fall – Modeling using Matlab

In this post, we will simulate the fall of an object dropped from a certain height in air. We will be using some numerical technique to find the time at which the speed of the object stop changing and to find out if this speed is reached

Boolean Operations in CATIA

Here is a quick explanation about Boolean Operations in CATIA and how you can use it in your project. It is hard to do without these techniques and it is always recommended (to beginners) to know how to use them early enough. A Boolean operation is similar to
