Vertices selection in Workbench

The above URL contains the entire discussion. Below is a snippet.


I am using ANSYS Workbench Version 19.0 where ,I want to assign the “point mass” on several vertices. For this I have data of vertices in following format

X cord, Y Cord ,Z cord , mass of vertices

In order to assign mass can I select vertices based on their x,y,z location. I have tried “Named selection” option where I have selected “scoping method” as worksheet, but it is available for x,y,z separately. It will be really helpful for me if anybody explain procedure to select the vertices for mass assignment.


The following python code will create point masses from a file “coordinates.txt”
which is located in the user_files folder of the current ansys project. In the
example columns are separated by tab. The columns are x,y,z and mass.
