two subdomain in fluid domain does not word (CFX)

hello!
2 Subdomain ,Volume force(ff) and volume heat source(h1) are load in fluid domain(slag). if only one Subdomain is load,the result of speed ​​and temperature is what i think right. but, 2 Subdomain are load together, the result is wrong ,why

thanks for any relay!!

------------------
SUBDOMAIN: Subdomain 1
Coord Frame = Coord 0
Location = SLAG
SOURCES:
EQUATION SOURCE: energy
Option = Source
Source = h1
Source Coefficient = 1 [W m^-3 K^-1]
END
END
END
SUBDOMAIN: ff
Coord Frame = Coord 0
Location = SLAG
SOURCES:
MOMENTUM SOURCE:
GENERAL MOMENTUM SOURCE:
Momentum Source X Component = x2
Momentum Source Y Component = y2
Momentum Source Z Component = z2
Option = Cartesian Components

I have no idea what the problem could be. It might be a bug in CFX. Are you using V14 of CFX?

ansys cfx(v13),
there is a bug in cfx?

No idea, you would have to report it to CFX to find out. But the first thing they will say is upgrade to the current version - so it is pointless doing anything about it until you update to V14.

Can't you put both sources in one subdomain? Or one as a source in the domain itself and one in the subdomain? Maybe this would fix the problem?
