Hello, I am stuck at how to assign different physical groups to different colors shown in image attached below, basically I am trying to given them different material properties in fenics to the physical tags afterwards but I am also confused on how to do that since I don’t know the geometrical loca…

What are the xyz coordinates in the Dat file? Do They correspond to vertex values or cell midpoints? As you have not given a minimal reproducible example, say a Dat file for a 2x2 unit square mesh, I cannot help you any further.

Assigning different physical groups to different color in gmsh and mark them as different material in fenics
