Hi,
I have a couple of questions regarding the [pmpd] object. It is not quite clear to me, what the messages to this object mean exactly. Actually I'm very confused about them.
As I see it, there are basically four messages possible to create the dynamic system: mass, link, in, out.
All of these take IDs as arguments. I don't understand the meaning of those IDs. For example to create a mass, one uses messages like:
mass ID MASS X
MASS and X are easy, but what is this "ID" used for?
"link" also takes IDs as argument, but it seems to ignore the ID given to a mass on creation, instead it seems to use its own IDs and it has an ID itself:
link LINK-ID MASS1-ID MASS2-ID K D
Where do I get the mass IDs from? In my experiments, it seems just have to keep track of them myself, and they have nothing to do with the ID I gave to a mass earlier. Or do I get it wrong?
Outlet creation (and inlet creation respectively): As I understand it, the format is:
out OUT-ID OUTLET MASS-ID AMPLITUDE
AMPLITUDE seems to be a scaling factor. OUT-ID I don't understand at all: what use does it have? Am I right to assume that OUTLET is numbered from 0 to max-outlet-number, where max-outlet-number is the second argument of pmpd minus one? And then MASS-ID: Does it start from 0 as well? Or from 1? Where do I get this ID from? In my experiments, it seems to have to be the MASS-ID I used when creating the "link"s.
Sorry for my confusion...
Ciao
