Hi all

I recieved excellent respond from good people about heat transfer analysis method las week. I really appreciate for those who kindly respond to me.

I'm gonna ask for help for another problem here.

In CFX post, there are several method to check the value of property (ex. temperature, pressure, velocity etc). The main methods to determine the location where i want to check the properties are 'line, point, point cloud, plane and volume)

But in the case which i have to check some property in specific 'plane', what kind of tool and how can i get the value of properties. (Because 'point' method only tell us about specific point information and 'line' method only tell us about '1-D' information, which in my case i want to know '2-D' information in the plane)

Recently i make a lot of 'points' one by one in the specific plane where i want to see the value of property. But it take too much time and as you can see it is very inefficient and unreliable. I wish i could see the value of property 'simultaneously' in specfic plane.

Is there any proper solution, please talk to me.

I would really appreciate.

Thank you.

Do you mean an average of something on a plane? Create a CEL expression: areaAve(Temperature)@Plane 1.
If you want all values on a plane, then
file/export/location: plane 1
and pick the variables you want to export.

Thanks for response.

As a matter of fact, i studied CEL tool to solve the problem. So is it right that i should make CEL expression and insert the information to 'table' or 'chart' or something else? The main problem i'm undergoing is that i'm not sure how to link 'CEL' with 'Post'.

For addition, as i expalined previously, i want an average of something on a 'boundary', not 'plane'. I cannot figure out how to locate a 'boundary' of domain in CEL expression.

I tried to find other people response about CFX post, but there are not much resource about CFX post in this CFD Forum so i write a thread in here.

I REALLY aprreciate for you help.

You can define CEL expressions in post, and evaluate them directly. Look at the expressions tab, right click/new. Enter your expression, apply, and you get your value. Boundaries or planes will work in the same way. Right-click in the data entry box, goto locations and you will see both boundaries and any plane you created. Im pretty sure this is described in any of the tutorials.
