Default CFX Monitouring on the region in domain??

My problem seems rather common,I have a region in the domain,it is something like interior face.(not a boundary nor an interfaee) But I want to make the integration of one variable (etc,pressure) on the region as one as one additional expression.

CFX11.0 can easily tackle the problem since its expression syntex allows like this" Avearea@REGION:user_region" while user_region is the name of the region I defined in advance.

But since our lab hasn't buy CFX11.0 ,so I have to use CFX10.0, while CFX10.0 doesn't support the syntex like "Avearea@REGION:" .In CFX10.0, what can be placed after @ is limited to boundary or interface. But my region is neither a boundary or an interface.

so I am wondering if there is any other approach to get the same result.

Thanks in advance

The only way to do this with 10.0 is to apply an interface at your region then write a call back to the interface region.

Dear Cyclone:

I have apply an interface at that mesh-surface

as you has suggested, but unfortunetly, CfX10.0

still dosen't recognize the interface name I have

difined which is strange with respect to the

documentation in CFX10.0 .If I replace the

interface name with a normal boundary name. Then

it does works , and no syntex error was reported.

What can I do then?

Many thanks.

You may need to force the interface to use a GGI connection. There is a parameter to toggle this at the bottom of the interface object definition panel. If you leave it as Automatic, the solver will recognize this as a 1:1 connection and simply merge the grid, thereby removing your region. Forcing it to be a GGI connection should preserve your region. There should be no effect on the solution, although the GGI will add a little extra overhead.
