How do I get the radial strain from the

I'm trying to plot the local biaxial strain (radial strain) on the top of the plate. The idea is to measure the displacement gradient along the center nodes. The geometry is symmetric.

What I was thinking was to export the normal elastic strain in the x and z-axis and find the magnitude. However, the geometry is still in the cartesian coordinates.

Is there a better way to go about this? Thanks for your help.

    Create a Cylindrical Coordinate System. Make the Z axis of this coordinate system go along the Global Y axis. Make the X axis go along the global X axis.

    Now create a Normal Strain plot using that new coordinate system. The X axis of that is Radial.
