2. Once you have calculated some arbitrary set of values for each node
for which you would like a contour plot, use DNSOL or *VPUT to put your
calculation results back into the ANSYS database (overwriting one of the
pre-existing result items) and then use PLNSOL or PRESOL (with FULL
graphics) to plot the redefined results.
