Hello,
Calling empty() on the DenseVector is causing the segfault. If I
copy the DenseVector into a std::vector, then it's fine.
How can I see if there is something wrong with my build/compiler?
Everything runs fine apart from that error.
The libMesh version is 0.9.5 (according to the first li
ntil exit from function
_ZTVN10__cxxabiv120__si_class_type_infoE,
which has no line number information.

Hello,
I just installed the most recent version of libMesh. I'm getting a
series of warning when compiling in dbg mode, all of the form:

Yes, eim_classes.h, rb_classes.h, and assembly.h all start and end with
something like
#ifndef __eim_classes_h__
#define __eim_classes_h__
...
#endif
There are no other .h files...

Hi,
Besides, since I updated to version 0.9.3, I cannot use Exodus any more.
The program crashes at the line e.g.
ExodusII_IO(mesh).write_equation_systems ("out_3D.e", equation_systems);
Maybe I missed something in the configuration, although I didn't change
anything w.r.t. last time. How can
few seconds. But
shouldn't the solver be the same?
Thanks for helping

Hello,
Now I should have slepc correctly installed with arpack. But still it
looks like I cannot use arpack in libmesh, since in the file
slepc_eigen_solver.C the arpack lines are commented out:
// case ARPACK:
// ierr = EPSSetType (_eps, (char*) EPSARPACK);
LIBMESH_CHKERRABORT(ierr); return;
Hello,
What do you think is the best SLEPC eigensolver_type for getting the smallest
(magnitude) eigenvalue and -mode? The eigenvalues in the spectrum are all real
positive. So far I've always used LAPACK, but switching to a 3D problem, that
becomes too slow and expensive…
Thanks!

Hello,
Our IT team developed a new procedure for installing libmesh on our iMac
machines, so that petsc, slepc, glpk, and eigen are called from the macports
that are controlled by them. The procedure - here below - works fine, I think
the girl called Vera wrote here to come up with it.
There's

Hello,
I'm sorry it took so long.
There were actually a couple of mistakes in my jacobian and residual.
Now for the small problem without specifying any options I get:

do without LU, but still it's very slow.

Hello,
I have an example based on miscellaneous_ex3.C, where I implemented a nonlinear
elastic problem with StVenant stress-strain law on a 3D domain 5x1x1, blocked
at x=0 and with an applied load at x=5. The problem is, the computation of the
displacement (along x y and z) is really slow (hou

Hello,
We are having some troubles with using libMesh on iMac workstations. The
problem is, the Macports are regularly updated by our IT team, and this could
lead to missing libraries and other issues from time to time. We had a
procedure to have libMesh installed on iMac and working on Xcode,
tting a compile error:
ex23aa.C(29): catastrophic error: cannot open source file "libmesh.h"
What's the right way to link then?
Thanks

Hello,
I just re-installed the newest version of Libmesh. All the examples seem
running, but the Make.common file has not been created in the main directory,
so I cannot link my own code to this newly installed version. Does that mean
that there's something wrong with the configuration?
Thanks

But I think here the initial guess is always the 0 function! How can I change
it to the solution at each step?
Thanks a lot,

Thanks for the many answers!
Still, according to the PETSc manual "matrix-free methods cannot be used if a
direct solver is to be employed", I think this means I cannot use

-pc_factor_nonzeros_along_diagonal" at the same time. Do I need some

Hello,
I'm modifying miscellaneous_ex3.C (2D Laplace-Young Problem Using Nonlinear
Solvers, in my current libmesh version). After adapting residual and jacobian

after one iteration with an all-zero (incorrect) solutio
