Node number CFX

Jiricbeng · January 4, 2016, 11:09

Analysis of the rotating machine consists of a few domains connected via stage interfaces.
I need to export pressure on selected surface (blade) and use it further. If I do the export in CFX Post I receive .csv file including a set of values x,y,z, pressure and node number. However, the node numbers always begin with 0, 1, 2 etc. Obviously these are not node numbers created during meshing. These are node numbers assigned by CFX Post.
According to what the .csv file is generated (sorted) when exporting the variables? Because it is not sorted neither according to x nor y nor z nor pressure.

Thanks for any help

Correct, you are getting the local numbering on the location being exported.

Did you check if the global node number can be exported as an additional column ? Check in the Geometric variables list.

No there is not such possibility.
