     This blog post is from an Indian Mechanical engineers perspective. Take it with a pinch of salt.

    It's a simple question with a very simple answer. The answer is, "Programming is everywhere".

     If you are a mechanical engineer and you think that only core mechanical syllabus is enough for you, then you are in for a shock. A famous saying (by me of course ) goes as, "An engineer with zero knowledge in programming is no engineer". That's for you as well.

So where do you use or where do you encounter programming?

    As a Mechanical engineer you'll encounter programming when you want to earn the big bucks. A basic knowledge in any programming language will give an advantage over your peers in the industrial market.

To give you a real world idea,

  • FORTRAN codes are used in ANSYS APDL.

  • PERL scripts can be use in conjunction with CCL (a native programming language) in ANSYS CFX

  • Python scripts can be used to automate tasks in ANSYS WORKBENCH.

  • Visual C++ and Visual C# are used in creating add-ins and for SOLIDWORKS.

  • VBA is used in macro programming in CATIA.

  • AutoLISP, C++ are used in AutoCAD.

    The above list gives you a rough idea on which programming language is used in production-centric software in the Mechanical domain.

     As a bachelors degree pursuing student, if you are looking for opportunities, I suggest you to pick any one from the above list and gain good knowledge in that field.

    My suggestion for a newbie would be to start from Python, as it an user-friendly programming language which is much easier to learn compared to others. It has its advantages and disadvantages. But for a newbie, the advantages far outweigh the disadvantages. We can summarize the advantages as,

  • Simple syntax. (You can read most of the code and understand what it does.)

  • No mandatory initiation. (Python scripts are dynamically typed, so there is no mandatory initiation of variables.)

  • Has excellent third party libraries. (If you are interested in dwelling deeper, you can easily learn Big-data analysis using python. Eg: Numpy, pandas, Tensorflow, etc...)

  • Simple setup. (Initial setup is simple. It's just a 30Mb file during installation.)

  • Great support. (If you have issues with your code, you can easily find assistance in the support communities. It has a thriving support community.)

  • Can be used in embedded system. (Micropython in embedded systems.)

  • Runs in almost any system and platform. (Even if you have potato computer, python can run in it.)

  • Free software. (Need I say more?)

    I urge every mechanical engineer to pick a programming language to widen your opportunity while you search for a job. A simple certificate course for programming language can go a long way in your career. A final piece of advice is for you to start working in Linux platform if you are planning a career in Research field, you'll thank me later.
