- Load the mesh and mode as usual, making sure that "Read Internal Volume" is enabled.
- Set up an appropriate mesh view.
- Hide the External Surface and show the Entire Volume (click the corresponding eye icons).
- Set External Surface Entire Volume drawing style to Surface if it isn't already (might default to Outline, which appears as a wireframe box)
- Set the surface to display a field you are interested in (so you can know that you will orient the sampling plane correctly)
- Select "Entire Volume" so that text is highlighted
- Create the sampling filter
- create the filter: "Filters -> Alphabetical -> Plane Glyphs". This will show a wireframe bounding box and a red outline for the plane orientation.
- Position the plane where you want it. The most consistent and repeatable way to do this is to put values in for "Center" and "Normal" which specify a point in the plane and the plane's normal vector, respectively. Change "Resolution" to 100, and hit "Apply"
- (Optionally) Save the data
- Presumably, this re-sampled data is to be exported, so make sure that only the re-sample filter is active and visible in the Pipeline Browser, then
- "File -> Save Data", type in a file name, set "Files of Type" to be "CSV" (Comma Separated Values) which is readable by spreadsheets and Matlab. Hit "OK".
- For "Configure Writer", you probably don't want to Write All Time Steps. And "Field Association" should be "Points". Hit "OK". (The file should be written to the same directory from which you originally ran ParaView, unless you navigated elsewhere.)
