Comparison of Program 8.6 result for a cube with 3D series solution
The time-stepping and output data follows next, and involve the usual parameters.
Output is requested at node
nres=21
. It should be noted that
ntime
and
nci
are not
read in this case because there is no contouring option in 3D.
The output from the program is shown in Figure 8.20, and gives the rate of pore pressure
dissipation at the centre of the cube. Figure 8.21 shows a plot of this result compared with
the 3D series solution from Carslaw and Jaeger (1959).
