Micro.blog is actually pretty nice. It is still a very small community. I would love to see it gain more traction.

There is no innovation when secrecy is involved.

Does anyone know of a similar website for mechanical engineering?

It meant, engineers who work on problems related to physics.

What sort of CFD analysis do you do? Automobile-related?

Hydrodynamics

Do you know of any learning opportunities such as internships where one can learn and apply Fortran?

Come to Boulder:

Huh. Don't think I have seen NCAR here before!

Look up for jobs in weather agencies, climate research, ocean model research and computational physics.

And lots of Finite Element Analysis packages still use Fortran under the hood.

I've noticed that Fortran comes up a lot when talking to people who do fluid dynamics simulations.

Curiously, it often does so in context of Python. One specific example I can remember was a library written in Fortran, with unit tests written in Python.

Fortran and Python go together very well (they complement each other in just the right ways and there's all the bindings / data structure compatibility with Numpy that you need). Glue code / UI in Python, Numerics in Numpy + homegrown Fortran, that's how I'd implement a numerical model from scratch today.

Just out of curiosity, what do you use for calling Fortran from Python (e.g. f2py, ctypes)? Do you have any suggestion about how to combine them together (e.g., for parallel calculations)?

So I haven't yet had the chance to do it myself, but yes I'd look at f2py first and how to integrate it with Numpy.

also a lot of computational fluid dynamics modeling (naval, aeronautical, automotive, etc.)

Thanks.

It's still used at NASA. The NASA Center for Climate Simulation at Goddard does much of their climate work in Fortran.

I have a friend who writes modern fortran nearly everyday as an actuarial pension analyst in Manhattan. They hired him out of college having never written a "hello world" script. Hope that helps!

Dead language tallying the dead?

I began my career 30 years ago writing actuarial valuations in Fortran77. Glad to see the industry hasn't changed (much).

Maybe universities. My mechanical engineering program taught fortran and had beowulf clusters running what was (presumably) fortran.

The thing with such hardcore engineering stuff is that there are very few places one can learn them at, but they are also very very cool
