NT UDFs & Face Coordinates
Dear all,

After many months of SGI Fluent work I've migrated to Fluent NT now, only to find that just to get SGI working UDFs to work on NT is more than a challenge!

Anyway, I've been trying to "convert" a set of UDFs to NT Fluent and I've pinpointed my problem to a single statement:


where: real coords[ND_ND];

The thing is that if I print (coords[0], coords[1]) the printout looks something like:

(1.157935e+00, -3.689349e+19)

(2.704321e+32, 1.045693e+00)

(1.183515e+00, -3.689349e+19)

where the coordinates of my model are always in the mm scale! This doesn't happen on the SGI where everything works fine. I've tried running as 3d and 3ddp and the problem still occurs.

Anybody experienced anything like this before? Maybe it's just me after so many hours of fighting... I don't know.

Any help would be most appreciated.

Cheerio! AL

Re: NT UDFs & Face Coordinates
Well, I sent that e-mail too soon. I still don't know how but the code I developed to try and make it work on 3ddp didn't work there but it did on the 3d version!

I can't quite explain it, but I'm happy cause it works. Still, if anybody has an explanation, I'd love to hear it, because I have quite a few UDFs to transfer to NT yet.
