Generate values at imported coordinates (xyz)

Hi there,

I have a simple model with a few cylinders on top of each other, each made up of a specific material. I also have a .txt file that specifies some 100 points by their x-, y-, and z-coordinates (three columns: x, y, and z). I wonder if there is a way for me to import the coordinate information into comsol and have comsol produce a new table with four columns: x, y, z, and some other material property of my choice. I have created a variable for the material property of interest, but I'm stuck at importing and processing the xyz coordinates. Many thanks in advance for the help!

Best, Max
