[petsc-users] Error with MatView on multiple processors

[Paul Urbanczyk]

Hello,

I'm having trouble with the MatView function drawing the matrix 
structure(s) when I execute my code on multiple processors.

When I run on a single processor, the code runs fine, and the graphics 
window displays cleanly.

When I run with multiple processors, I get error messages (see below).

The matrices are constructed with DMCreateMatrix(da, &A_matrix).

I then set the values with 
MatSetValuesStencil(A_matrix,1,&row,2,col_A,value_A,INSERT_VALUES).

Finally, I call MatAssemblyBegin(A_matrix,MAT_FINAL_ASSEMBLY) and 
MatAssemblyEnd(A_matrix,MAT_FINAL_ASSEMBLY).

I also test that the matrices are assembled with MatAssembled(A_matrix, 
&is_assembled_bool), and it appears they are successfully assembled.

Any help/advice is greatly appreciated.

Thanks in advance!
