Must-to-learn-courses-in-mechanical courses

In this competitive world,securing good marks in college exams is not sufficient to end up with getting high paid jobs.One must need to enrich himself/herself by learning some of the software courses pertaining to mechanical engineering.

Here is the list of must to learn courses:

•DESIGNING:It is one of the domain  of mechanical engineering which has high demand in engineering job markets. Working as design engineer for a company,one can earn higher amount of money and thus can excel in life. A design engineer must be able to create any type of 3D sketches from 2D sketches. For this, design engineer should have adequate amount of knowledge about design softwares like CATIA,SOLIDWORKS, AutoCAD and ProE.

1.CATIA- CATIA is an acronym of Computer aided three-dimensional interactive application. It's an integrated form of computer aided drawing(CAD),Computer aided Engineering(CAE) and Computer aided machining(CAM) application for digital product development and product life cycle management. 

Developed by French company,Dassault systems,it is high and modelling and designing software.

Benefits:

(a) Create any type of 3D part from rough 3D sketches to fully detailed industrial assembly.

(b) Enables  smooth evolution from 2D to 3D modelling of designs.

(c) Has a wide range of applications for tooling design and for generic tooling.

(2)SOLIDWORKS- SOLIDWORKS design solution helps designers and mechanical engineers to create and deliver great products. Like CATIA,it is also developed by the Dassault systems. Used by 20 lacs + designers and engineers, SOLIDWORKS  proves to be pre-requisite software in the designing field.

(3). AutoCAD- AutoCAD is a line for 2D and 3D design software produced by the Autodesk company. At the earliest stages in the design of product,engineers use AutoCAD to start sketching design and analysing them to find out the best solution.

(4)ProE- Other design softwares which can learn is ProE also known as PTC Creo or CreO parametric. Developed by Parametric Technology Corporation,it's a design software which provides assembling,modelling Finite Element Analysis and NURBS surface Modelling and many more. NURBS stands for non uniform rational basis spline. It's a mathematical model used in graphics for generating and representing curves and surfaces.

•Simulation: Simulation helps product engineers to understand complexity of engineering problem through the design produced by this technique.

Softwares available for simulation technique are:

(4)Simulink- Again,this is one of the software which has high demand in the job market. It is a platform for multi domain simulation and model based design of dynamic systems. It provides an interactive graphical environment and customizable set of block libraries that enables engineers to design and simulate accurately.

(5)SOLIDWORKS- Along with designing,this software can also be used for simulation purposes. Solidworks simulation can be used in the analysis of

(a) Structural Finite Element Analysis(FEA).

(b) Fluid flow and heat transfer(CFD).

(c) Plastic injection moulding.

(d) Time based motion.

Intuitive CFD simulation takes advantage of integration,advanced geometry and automatic flow regime determination. Mechanical engineers and CFD experts can estimate flow fields mixing processes and heat transfer with the help of SOLIDWORKS simulation technique.

(6) AutoCAD- One of the most useful function of AutoCAD is its ability to provide a graphic simulation of a how constructed machine functions.

(7)ANSYS-ANSYS for mechanical engineers is a concept that has a very wide scope. This software makes use of numerous concept of mechanical engineering like fluid dynamics and heat transfer to arrive at solution. It uses the concept of FEA for analysing the structure.Its applications include analysis of electrical problems mechanics and construction.

Advantages:

(a) It can import various geometric shapes from different CAD software and use them to perform simulation.

(b) 2D and 3D geometric shapes can also be created using this software.This is done through in-built CAD developing in ANSYS like Design Modeler and Space Claim.

(c)ANSYS is capable of integrating various formula into one platform to make the analysis process simpler and faster.

Fields of application Where ANSYS are used:

•Non-linear applications

• Dynamics

 •Composites

•Hydrodynamics 

•Structural analysis •Heat transfer

•Programming languages- One shouldn't be in the chimera that programming languages are meant for students from CS and IT branch in Engineering.The basic knowledge of some of the programming languages is must for mechanical engineers as well.

(8) Python-Python can be regarded as the most basic and easy to learn programming languages among all the programming languages. It is a simple language to learn but it has various applications in the field of Engineering.

Fields of application:

(a) Numerical analysis- One of the common application is to perform numerical analysis. Software Giants like Google and Facebook hire Mechanical Engineers to ensure efficient and safe thermal management of their database and cluster of computers in their companies. These engineers use MATLAB/Python to write scripts and then import them to CFD software to test numerous designs.

(b) Computational fluid dynamics(CFD)- In the field of CFD,it has numerous applications. In order to simulate ,one requires to write scripts in Python/MATLAB.

(c) Robotics and Automation-Mechanical and automobile manufacturers use python to automate even when the script  is in another language, it is written in Python before automation since it is the most common language and hence acts as the interface between industries and codes.

(d) Dynamics of machinery-It finds its applications in areas like vibrations and dynamic motion, simulation and modelling engineering.

(e) Gaming- Many online games are created using Python as one of the language.

(f) Thermodynamics- Because of huge in built library and simple syntax, complex problems of thermodynamics can be solved with the help of python.It is used to solve chemical kinetics, fluid dynamics,etc.The only thing you need to do is writing an appropriate code to come out with the required solution.

(9) C programming- C programming is also one of the most common and basic language among all the programming languages and hence it finds its uses in various field of mechanical engineering.According to one of the website, C programming is the most learnt programming language.

(10)MATLAB -This software has become one of the must learn course in mechanical engineering field. Recruiters give more attention to those who has the knowledge of MATLAB.It is a high level technical computing language which provides interactive environment for algorithm development,data visualisation,data analysis and numeric computation.Using MATLAB one can solve technical computing problems faster than the traditional programming language.One can conglomerate MATLAB codes with other programming language codes.

•Conclusion:

In my opinion, learning enthusiasts must learn at least one software from each of the mechanical engineering domain.

 In designing, CATIA is likely to be the most appropriate software to learn.For simulation purposes, ANSYS is the best one.In programming language,Python should be more preferable and MATLAB is must to learn software.

Some of the websites which can be helpful for mechanical engineering students are GrabCAD, Fractory, Engineering Toolbox, Engineers Edge and Matweb.

Online learning platforms:

• One can find a large number of YouTube videos to learn each of the softwares free of cost.  NPTEL courses which are being taught by IITs professors is a big name in this list. Online educational platforms like Khan Academy, Udemy,edX and Coursera  are some of the reputed educational platforms where one can learn any of the software along with certificate after the completion of the course at reasonable amount of money.
