Hi LibMesh developers, I am using the NonlinearImplicitSystem for solving Poisson's equation. I get many warnings in the solve() stage from ParMetis which look like this:
Missing edge: (8785 9034)! Vertex 9034 contains a self-loop (i.e., diagonal entry in the matrix)! Missing edge: (7278 9034)! Edge 7278 from vertex 9034 is repeated 1 times I'm not able to figure out the problem. Here I'm only using 1 process. I'm using LibMesh 0.9.4 compiled with PETSc 3.5 in debug mode. I have enabled parmesh. Any ideas what the problem could be? Here's the backtrace: #0 0x0000003ab5232625 in raise () from /lib64/libc.so.6 #1 0x0000003ab5233e05 in abort () from /lib64/libc.so.6 #2 0x0000003ab522b74e in __assert_fail_base () from /lib64/libc.so.6 #3 0x0000003ab522b810 in __assert_fail () from /lib64/libc.so.6 #4 0x00002abf576465a1 in libmetis__SetupGraph () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #5 0x00002abf57625f15 in METIS_NodeND () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #6 0x00002abf587e1e88 in dmumps_195_ () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #7 0x00002abf5870b8fe in dmumps_26_ () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #8 0x00002abf587bd2dc in dmumps_ () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #9 0x00002abf586d5f83 in dmumps_f77_ () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #10 0x00002abf586b3403 in dmumps_c () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #11 0x00002abf57d5b060 in MatLUFactorSymbolic_AIJMUMPS(_p_Mat*, _p_Mat*, _p_IS*, _p_IS*, MatFactorInfo const*) () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #12 0x00002abf57d79cdc in MatLUFactorSymbolic () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #13 0x00002abf58067584 in PCSetUp_LU(_p_PC*) () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #14 0x00002abf5801a389 in PCSetUp () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #15 0x00002abf58101d4e in KSPSetUp () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #16 0x00002abf580fdb46 in KSPSolve () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #17 0x00002abf58596f2f in SNESSolve_NEWTONTR(_p_SNES*) () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #18 0x00002abf581d7ba2 in SNESSolve () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 #19 0x00002abf573335bd in libMesh::PetscNonlinearSolver<double>::solve(libMesh::SparseMatrix<double>&, libMesh::NumericVector<double>&, libMesh::NumericVector<double>&, double, unsigned int) () from /depot/ncn/apps/conte/PETSc35_Intel15_no-mic_debug/libs/libmesh/libmesh/.libs/libmesh_dbg.so.0 Thanks!
