Well, let me Cc: the list with my replies, and hopefully the next person to search will have an easier time.
1) I will solve the non-linear 2D~3D Poisson problem with implementation of PETSc, then what kinds of configuration options (for optional packacge) should I used? (except PETSc)
For optional features I usually use --enable-everything (which turns on a half dozen borderline useful options) but there's nothing in those which you really *need*, and for other options we try to enable a good default configuration without you specifying everything on the command line. For optional packages, the only thing that's really important is PETSc for parallel solves (or Trilinos, but I prefer PETSc) and SLEPc if you intend to solve eigenproblems.
2) Is there no option "--download" instead of "--with" in configuration as like PETSc?
I'm afraid not. For a couple packages we keep "contrib" directory copies.
3) In example of introduction_ex4, my computer displayed the different performance log,
Sure, and that's expected and okay. The PerfLog values will differ depending on what computer runs the program and on what the libMesh configuration is, and performance logging can be turned on or off entirely at configuration time or run time.
4) I want to display the visualized result of introduction_ex4, which can be implmented with Paraview. How can I display the visualized result?
If your libMesh was configured with Exodus support, then introduction_ex4 writes "out_2.e" in 2D and "out_3.e" in 3D, and you can open either of those in Paraview. Exodus is one of those packages we keep a "contrib" copy of, so it should have been configured in unless you specifically disabled it. --- Roy ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
