Dear all,
I'm trying to understand how to use the recent natural-global mappings that
have made it into dmplex. The goal is to do checkpoint restart (onto, perhaps,
differing numbers of processes) with DMs with a non-zero overlap (I can see
that this is currently unsupported, but let's try
Hi Barry,
The routine DMCreateMatrix_DA_3d_MPIAIJ has 2 input arguments (DM da, Mat
J), the function pointer in DMDASetGetMatrix() only accept function with
that two arguments.
As you suggested, I am writing a routine (based on
DMCreateMatrix_DA_3d_MPIAIJ())
to preallocate the matrix in the way I
Dear friends,
I need to read a matrix from a text file (txt).
This matrix has a high dimension (2000 X 2000) .
Example: date.txt - provision in the text file:
1 2 3 5
5 5 7 8
5 6 8 9
What's the proper way to perform the action?
thanks for help

Hi Matthew,
So I’m discretizing via a tensor product of Lagrange polynomials co-located at
the Gauss-Lobatto-Legendre (GLL) points. The polynomial order might range from
4 to 10 or something like that. The current problem is solved on 2D hexes.
I had found DMPlexCreateSection, and followed
