Hi,
I am using parallel environment to read an unstructured grid data so that each
process is assigned one part of data.
But there is an error when running the program (mpiexec -n 2 ./out) at the
following codes:
eqsys = new EquationSystems(*mesh);
asys = &(eqsys->add_system<System>("Velocity"));
Ax_var = asys->add_variable("Vx", FIRST, LAGRANGE);
Ay_var = asys->add_variable("Vy", FIRST, LAGRANGE);
Az_var = asys->add_variable("Vz", FIRST, LAGRANGE);
eqsys->init();
The error is:
Error: EigenError: EigenSparseVectors can onSparseVectors can only be usely be
used in serial!d in serial!
[1[0] ./inclu] ./include/libmesh/de/libmesh/eigen_spareigen_sparse_vector.h,
line se_vector.h, line 506, compiled Jun 11 2016 at 16:06:07

application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 1
It seems that the error occurs at eqsys->init(). Is there any wrong operation
here? Thanks.
Best regards,
