How can I calculate the average fieldl value of a section?

Hello,

I'm doing a CFD analysis using Acusolve and Hyperview for post-processing.

I want to obtain pressure and velocity averages in some sections in the model and until now I did it using 'Query' and selecting nodes by plane, using a small tolerance and selecting the base node in the section. Then I get the table with the velocity value for each node and calculate the mean value in other software.

I realised that the values of average that I obtain like this aren't the good ones, because I want to calculate the field average. Do you have any idea of what can I do?

    Currently you can do that in AcuFieldView.  Create a coordinate surface (assuming you want x, y, or z plane) then use the Integrate functionality to get the values on that coordinate surface.

    This will eventually come into the post-processing capability within HyperWorks CFD also.

    Ok thanks! I could get it but I can't visualise the coordinate surface that I create. Is that posible or is only availabre for the calculation?

    First, make sure other display surfaces (boundary, other coordinate, etc) are not covering/hiding the surface in question.  Second, make sure the coloring/display types for the coordinate surface are such that they are visible.  (For example, a geometric coloring of black on a black background will not be seen.)  You can set the type to 'smooth' and coloring to 'smooth' and select the desired scalar by which to color.
