Hi!
I have some other questions: I'm guessing that in the xdmf_points_0000.dat and xdmf_points_0001.dat the number 0 or 1 refers to the x coordinate and y coordinate, but what about the other variables, do they refer to the component x and y of the variable? If so, what happens when dealing with a scalar?
Thank you!
