Hi,
I have done some more testing, and the culprit seems to be the graphic
engine. Having commented out the following two expressions from Karl's
original notebook,
Timing[Plot3D[Sin[x y], {x, 0, 2 \[Pi]}, {y, 0, 2 \[Pi]},
PlotPoints -> 4000, DisplayFunction -> Identity]][[1]],
Timing[Plot3D[Evaluate[q4[x, t]], {x, -40, 40}, {t, -40, 40},
PlotPoints -> 2000, DisplayFunction -> Identity]][[1]]
Mathematica did not consume too much memory.
Moreover, if one loads the legacy graphic engine
In[1]:= << Version5`Graphics`
then evaluating the following expression
In[2]:= Plot3D[Sin[x y], {x, 0, 2 \[Pi]}, {y, 0, 2 \[Pi]},
PlotPoints -> 4000, DisplayFunction -> Identity]
Out[2]= --SurfaceGraphics--
works fine. However, evaluating the same expression with the new graphic
engine eats up all the memory available.
In[3]:= << Version6`Graphics`
In[4]:= Plot3D[Sin[x y], {x, 0, 2 \[Pi]}, {y, 0, 2 \[Pi]},
PlotPoints -> 4000, DisplayFunction -> Identity]
Regards,
Jean-Marc
