Hi, All I tried snes/examples/tutorials/ex3 on my Mac OS 10.7.5, with X11 (XQuartz 2.6.5 (xorg-server 1.10.6)) installed. Everything seems fine, as I got output from the terminal as:
====================== atol=1e-50, rtol=1e-08, stol=1e-08, maxit=50, maxf=10000 iter = 0,SNES Function norm 5.41468 iter = 1,SNES Function norm 0.295258 iter = 2,SNES Function norm 0.000450229 iter = 3,SNES Function norm 1.38967e-09 Number of SNES iterations = 3 Norm of error 1.49751e-10 Iterations 3 ====================== I suppose it is right. The only thing which bothers me a little bit is the x-window plot. When I ran the code, I could see a x-window plot flashing on my screen and it's gone forever. I don't know if it is supposed to be like this, or I should see an x-window plot staying on my screen. Anyway, this is not a big issue and I guess it is most likely not a PETSc problem. My X11 should be fine too, as when I do gnuplot, the x-window shows stuffs correctly. However, I'd appreciate if anyone could give a hint how to resolve it.
