Runge kutta Matlab code

This is an exercise which is solved just for the purpose of comparing two numeral methods and see which one of them is more accurate. Here we will be using Matlab to solve the equations with two different methods, which are: Second order Runge Kutta method and

NX CAD

NX is a very powerful CAD software by the German's company Siemens It is a widely used software nowadays. In this NX CAD tutorial, we want to create a Protective Back Cover of mobile in NX 8.0. A Protective Back Cover is usually made up of Silicone.

Modeling a Car Tire in CATIA

You most probably know that tires play a major role in suspension of an automobile and diminish fuel consumption. And tires shapes varies according to the nature of the road. In this tutorial, we are going to do some modeling, and the object we will be modeling

NanoCAD – AutoCAD Alternative

NanoCAD is a free CAD software having a quite similar interface with AutoCAD. NanoCAD allows you to create DWG compatible CAD files which you can share with AutoCAD users. Nanosoft also provides an advanced version of NanoCAD which is a paid version: NanoCAD PLUS If you have

How to draw a star

This is how to draw a star using a protractor and some common sense facts. How to draw a star, method 1 A perfect star has all edges uniformly distributed around a circle. Means, if we have a 5 points star with edges A, B, C, D

How to plot a circle in Matlab

Here is  how to plot a circle in Matlab Plot the unity circle in Matlab Code Angles=(0,2*pi,100); plot(cos(angles), sin(angles)) Plot a circle in Matlab with a given radius Angles=(0,2*pi,100); plot(9*cos(angles), 9*sin(angles)) If you need MATLAB homework help from coding experts, you can visit this site.

Top Ten Most Used CAD APPS

As the world migrates from relying solely on personal computers and desktop work stations to the mobile age, almost every operation that requires a PC to function can now easily be done with the use of mobile apps and the world of computer aided graphic design is

Euler VS Runge kutta – Circle – Matlab code

In the context of this exercise, lets suppose having the two dependent following function: With initial conditions The equation of a circle look like the following where the r is a constant. If we add our equations at 0, the following will be true We are now

Surface Modeling in CATIA – Part 2

We have recently learned how we can create simple surfaces in Generative Shape Design workbench. In this tutorial, we are going to learn about operations carried on surfaces using CATIA. The tools we are going to require can be found in Operations toolbar. Operations Toolbar Most common

How to design a Buck converter in Matlab

A Buck Converter is a DC – DC step down voltage converter (can also be considered like step up current converter) . Here is how you can use Matlab to simulate a Buck converter (Note: In this post, we will consider switches as ideal) In order to

Graphic Design Software for Beginners

The popular Malcolm Gladwell 10,000 hour rule which states that it takes an individual approximately 10,000 hours to become a master of his or her craft is definitely one that must be taken to heart by anyone seeking to become a design guru and this is because

Surface Modeling in CATIA

CATIA is one of the most used software in automobile and aviation because of its advanced surface modeling techniques. Very complex surfaces can be modeled in CATIA. Popularly its Generative Shape Design workbench is used to design surfaces. One might wonder why surface modeling is so important.

Constraints used for a sketch in CATIA

Only a precise 2D geometry will create a precise 3D component. To create a precise 2D sketch in CATIA, we use constraints. What  does “constraint” actually means? It means that we are restricting the degree of freedom of the sketch. Consider, you want to constraint a line.

How to draw a Pulley in CATIA

This post shows you how to draw a Pulley in CATIA using Boolean operations. There are many reason you as a beginner should master how to use Boolean operation in CATIA. It is one of the preferred method used by CAD designers for the following reasons. It

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

How to draw a Soap case – CATIA

Welcome to one more 3D exercise. We will be having fun learning how to draw a soap case in CATIA. This exercise is designed to help you learn new commands from Part Design.   Most time for beginners, its easy to test your CAD skill on things

Catia Exercise – Creating a Flask

This exercise is designed to help you learn new commands like Multi-Sections Solid, Shell and more. The figure below shows a flask which we will use as goal to help us have a reason to play with CATIA today. This flask has nothing but basic rounded shape,

Drawing a circle in AutoCAD

Drawing a circle in AutoCAD is one of the most fundamentals while learning how to use the software. In AutoCAD there are many ways to draw circles, and all these ways depend on your inputs and the feature you want your future circle to have. The simplest
