Can you post your error message too? I'll dig up my code later and see how the syntax differs.

BTW: you have a typo in your code:

Andy,

Can you post your code so we can see what's going on? You need to setup a few things before you can access faceZone data.

H25E,

I think you block mesh may be a *little* too coarse for your case. Try increasing you refinement, or decreasing the size of your domain (since this is just a test case).

jhoepken,

I tried this, but the faceSet I created included internal faces in my bounding box.If I can create a faceSet from a patch, that would work, so I'll look into that.

Thanks!

In this case, there is only one boundary patch (a wall) and then some exposed internal faces.

Is it possible to query a patch within a cellZone?
