TJ,

I said ""real" computer languages". I didn't say anything about the hardware.

A PLC is a computer.  Bad code in a PLC will fail just as fast as bad code in any other computer. "real" computer languages could be supported on PLC's.

In my opinion, "Ladder Logic" is a language that does nothing to promote writing "good" code.  It is very easy to write code that is frought with side effects, and difficult to write reliable code. (My opinion, based upon my own experiences and observations)

I understand why a company wants to be proprietary with their products (so they can make more money), but it drives me crazy when there are standards that they defeat in order to make people have to stay with their hardware. I used to do a lot of IEEE programming and while most GPIB cards could be swapped out - one specific company insisted on making it impossible without buying special software drivers from them or you were stuck with their specific software package. I see what some folks are saying - basically, "dance with the one that brung ya" but that isn't always possible. I am in favor of universal platforms as much as possible. I was thrilled when I was working on a microcontroller project and I could program a DS5000 with the same code that I wrote for an 8751 (okay, I know that isn't really realistic but in the early 90s it was) - why can't we all just get along?

The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
