How to export field values on the surface of an object along with coordinates
Export field values on the surface along {x,y,z}
Solution:
Field values on the surface of an object can be exported along with the coordinates using the Fields Calculator as follows:
- Select the field quantity from the ‘Named Expressions’, for e.g. Mag_E.

- Select the surface of the geometry

- From the Output stack, choose ‘Value’.

This will create the expression

- From the Output stack, select ‘Write…’ and specify the file name in the pop-up window to save the *.fld file which will contain 4 column data with coordinates followed by the value i.e. {x, y, z, f(x,y,z)}.
