A screwdriver is vodka and orange juice.  A hacksaw has orange soda
as well.

Use of orange juice in hacksaw is disputable.

So you’re talking more chemical cutting tools rather than ones for
chemical assembly?

I noticed that it says “Microsoft® Windows® has become the standard
for desktop graphical computing”, and it seems like the text hasn’t
been updated since about October 2014. I would say that assertion is
getting a bit long in the tooth, wouldn’t you agree?

I had a look around, and this popped up <https://dwsim.org/>. It
certainly seems to have better cross-platform support.

Also I see you’re listed here

along with a bunch of other alternatives. And here
<https://www.simulatelive.com/product-reviews/simulation/review-of-open-source-process-simulators>
is a review of various open-source products (including DWSIM), which
concludes that they lack nothing compared to the proprietary ones.

It is very hard to compete with the price of free.

We have quite a few features that they do not have but that is for 
another day.  DWSIM has a very loyal following and many of them 
participate in the programming of new features.

That’s the way Open Source should be. Too often we see people
complaining that some app doesn’t have features that they desperately
need, so they have to go back to paid proprietary software. Completely
overlooking the fact that, if they put some of that money they would
pay the proprietary software vendor towards sponsoring the development
of some of the features they need, the result would benefit everybody.

But would that be an advantage to that user?  Benefiting everybody means 
benefiting your competition as well.  I have no idea how competitive or 
cooperative the users of chemical simulators is, but it is not always 
the case that "benefits everyone" is a win for the person or company 
stumping up the cash.  In many markets, there is room for pure 
closed-source commercial software, pure free and open source software, 
and many combinations in between.  Simplistic "everybody wins" arguments 
are rarely applicable.

The know-how is usually in the models, not in the tools.  When
running chemical simulators, or more generally scientific/technical
software, people are usually glad if they work for them at all.

I have to admit that there I do not work with chemical
simulation software.  There is an equivalent that I am more
familiar with.  https://openfoam.org/ , an open source CFD
software.  (There are actually two versions of OpenFOAM, but
that is another issue).  This software is developed by a few core
people and supported by a consortium from the chemical industry,
https://openfoam.org/chemical-process-engineering/ .  Each company
pays a certain amount and can influence the work done on the
program proportional to the money they contribute.

OpenFOAM is a bit special because of it is script-based and has
a fairly steep learning curve.  Universities use it a lot because
it is free of cost to them (unlike commercial programs like Ansys
Fluent), and somebody doing a PhD also has the time to learn it,
unlike in industry.  With the licensing policies of companies like
Ansys, which make software for universities very expensive, they
are disconnecting themselves from their own potential user base
of the future.

We force all loops in simulations to go through a minimum of three 
iterations.  What appears to be converged may not be converged in reality.

The f2c runtime is an undocumented mishmash of a nightmare given that 
they started with the unix f77 compiler.  I would prefer not to use it 
but, I could be forced into it from a time aspect.

In this particular case, it is a converged solution from a prevous
iteration, which then promptly diverges, you have to perturb it to get
it to converge again.  How Aspen gets away with this, I don't know.

Huh, that does not make sense.  One needs variables to decomplicate 
complex calculations.  We even support common blocks in our F66 
interpreter user code so that variables can be stored from one iteration 
to the next.

You could use them via implicit typing, but you could not declare
them.  So, REAL A did not work (DIMENSION probably did).

Actually, the way I used them was mainly for a colleague who had
zero Fortran experience, and I got a few needed routines running.

I expect your customers would appreciate having an extension language
that works at a somewhat higher level than Fortran -- and an
antediluvian version of Fortran, at that.

Why are you being so hard on the guy?  He started a thread that has had 
broad appeal and interest, and successfully pulled in participants from 
two language groups in an amicable discussion.  He has been nothing but 
open and honest, discussing his company's design choices and giving 
reasons for them (whether they are good technical reasons or not).

A Basic or Basic-like interpreter can be a very useful addition to large 
software.  It can make it easy to write small snippets or scripts for 
automation purposes, and can be learned quickly and easily even by those 
with no programming experience.  It's a language that has scaled from 
microcontrollers to mainframes.  There are plenty of alternatives for 
embedded languages in software, but let the guy who knows the program, 
the code, the development team, the company, its customers, and the 
software's market pick the best choice (or choices).  Stop 
second-guessing him just because you read a Wikipedia page.
