[Libmesh-devel] Problems with MeshFunction in parallel

2008-05-08 Thread Martin Lüthi
Hi MeshFunction does currently not work in parallel. When I try interpolating a function I get [yak:14801] *** An error occurred in MPI_Allreduce: the reduction operation MPI_MAX is not defined on the MPI_CHAR datatype [yak:14800] *** An error occurred in MPI_Allreduce: the reduction operation

[Libmesh-devel] Compiling problems

2008-04-29 Thread Martin Lüthi
Hi again As you can tell, I'm compiling Libmesh on different machines. Now I stumbled on some (trivial) errors when using the Gnu compilers 3.3.5 (that I am sort of forced to use on one system). All errors occur with svn:2813, and are probably due to some template acrobatics that the compiler can

Hi Thanks for your answers. While I could not figure out what was wrong (I got no more information in debug mode), using PETSc 2.3.3-12 works smoothly. The crucial thing seems to be the usage of the mpi compilers. > ./configure --with-cxx=mpicxx --with-cc=mpicc --with-f77=mpif77 Should that be

Hi there After being able to compile SVN-Libmesh with the option ./configure --with-cxx=mpicxx --with-cc=mpicc --with-f77=mpif77 together with PETSC petsc-2.3.2-p10 (openmpi), I get the following error message when running example 13 (it *has to be* the 13!): *** Solving time step 0, time = 0.0

[Libmesh-devel] Data format documentation

2007-11-24 Thread Martin Lüthi
Hi Libmesh supports a wide variety of data formats. For some formats the documentation is easily accessible, but for some (e.g. UNV) one has to hunt down some description of the file format. I think that it should be mandatory to put the file definitions into the the doc tree (as has been done f
