PROMO links?

PROMO links?

PROMO links?

(OP)
Does anyone have any web links to PROMO (the German engine simulation code) web sites/pages?  Alternatively, does anyone know what kind of solver it's based on?

RE: PROMO links?

I thought Promo was BMW's in-house code?

Cheers

PROMO is used by the Germans, most of whom have versions of its source code.  I think it may have come from a University or consortium originally.  I know for a fact that BMW, VAG and Porsche all use it.  Not sure about DC though.

RE: PROMO links?

well, don't bother googling for "promo engine" !

Have you had a flick though engine technology international?

RE: PROMO links?

Been googling for a while with no real hits.  I did find out from a 1997 paper from our own library that PROMO is a finite volume code (as opposed to a MOC, which I'd suspected) but not much else.  I think it uses a collocated grid, but I'm not sure.  I guess not many Germans subscribe to this forum?

RE: PROMO links?

Often these codes are based on a university project, maybe you can find out which uni it was developed at.

RE: PROMO links?

I work in Germany now. I believe the code was originally developed at Aachen, and BMW, Mercedes, at least HAD copys of them BMW have since gone over to GT Power as have Porsche and Merc. I don't know how much BMW uses it now. You're right in that it is a Finite Volume code (but I don't think it's FRAM or Lax Wendroff), and not Method of characteristics and I know it has also been used succesfully in NVH prediction work, which makes me wonder whether it is centre biassed in ressolving the spurious gradients. I don't know if it uses a Collocated Grid.

I've heard it uses a look up table for junction losses, but that's not what you asked!
