Re: [Libmesh-users] EigenError when running parallel for reading data

It seems that this is caused by non-ghosted values. The NumericVector only contains the solution of nodes owned by one process. But the elements (mesh cells) owned by one process may include the nodes owned by other process. In my program, the data contains 8 nodes and 6 elements. By using 2 pro

Re: [Libmesh-users] EigenError when running parallel for reading data

Thanks. I have another problem about parallel reading the nodal values. Below is the code. I run mpiexec -n 2 ./out , and get the error that: [0]PETSC ERROR: - Error Message -- [0]PETSC ERROR: application called MPI_

Re: [Libmesh-users] EigenError when running parallel for reading data

Hi, I have rebuilt libmesh with PETSc. Here is an simple example that to obtain the nodal values. However, when I run it in parallel (mpiexec -n 2 ./out), there is always error that: [1]PETSC ERROR: - Error Message ---

No you may run serial if you wish. On Tue, Jun 21, 2016 at 12:40 PM 张江 wrote: > Thanks. So I have to build libmesh with PETSc? > > > On Jun 21, 2016, at 1:35 PM, John Peterson wrote: > > > > > > > > On Tue, Jun 21, 2016 at 12:28 PM, 张江 zhangjiang.d...@gmail.com>> wrote: > > Hi, > > > > I am us
