Did you try to save the mesh in the 2.0 version format directly from gmsh? I did it and libmesh was able to read it.

In order to solve it, I manually edited the msh file and change the version from 4.1 to 2.0. After this edit, I faced with another error which is about ntag. I do not know how to solve this issue. *./example-opt d 2 Corr-Mortzea-1.ms<http://Corr-Mortzea-1.ms>h ** **Warning, ntags=377738, but we currently only support reading 2 flags.** **Element type 52414 not found!** **Stack frames: 9** **0: libMesh::print_trace(std::ostream&)** **1: libMesh::MacroFunctions::report_error(char const*, int, char const*, char const*)** **2: libMesh::GmshIO::read_mesh(std::istream&)** **3: libMesh::GmshIO::read(std::__cxx11::basic_string, std::allocator > const&)** **4: libMesh::NameBasedIO::read(std::__cxx11::basic_string, std::allocator > const&)** **5: libMesh::UnstructuredMesh::read(std::__cxx11::basic_string, std::allocator > const&, void*, bool, bool)** **6: ./example-opt(+0x157c4) [0x55824fe737c4]** **7: __libc_start_main** **8: ./example-opt(+0x15b5a) [0x55824fe73b5a]** **[0] ../LIBMESH/src/mesh/gmsh_io.C, line 371, compiled Mar 22 2019 at 21:22:33** **--------------------------------------------------------------------------** **MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD** **with errorcode 1.** ** **NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.** **You may or may not see output from other processes, depending on** **exactly when Open MPI kills them.* I am highly thankful for your help and guidance, Thank users and developers of libMesh _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net<mailto: Libmesh-users@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/libmesh-users _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
