RTZ Range Tool to generate Circumferential Average

Using roughly the same Python tool posted in the previous entry (RTZ Range Tool), I modified this tool to loop through the theta range and report back the distribution in the circumferential sense. This is useful when looking at some type of an average quantity as you traverse in theta, rather than using a line (which only reports back the local non-averaged value). The added benefit of using this small pie slice volume is that you can look at a more average quantity, rather than an unique quantity at a finite single point.

This routine shares about 85% with the above interactive routine, including all of the logic for the creation of the RTZ range selection. This routine has the added “loop” at the end of the routine, were the resulting RTZ range clip is then swept around through 360 degrees and a query of a variable is made.

The Batch version differs from the previous Interactive RTZ Clip tool in the following manner:

  1. It is made for batch operation (settings at the top of the file for input).
  2. It uses a single axial value, and this ends up as a thin clip.
  3. It uses a theta sector (say 5 degrees for example), and loops through the entire 360 deg range.
  4. It queries a variable on this clip part, and builds a Query and Plotter as a result.

The main goal for this tool is to be used in batch, and query a particular variable as a function of theta (over a sector plane).

An example screencast tutorial, dataset, and python routine for this batch python routine can be found at :



The same example manifold model is used for this case. A sample output from this routine yields the following type of graph:

The intention for this type of code is to allow the user to query a value on a segment in theta (rather than a single theta value), and report this back as a query and plot. This routine also works in batch mode, with a few user inputs listed at the top of the python routine.
