Re: [Libmesh-users] how to read a distributed mesh

[Jahrul A. <al...@mu...>]

Ok, I have created a simpler example.

1) CheckpointWrite.png -- screenshot showing the output when writing the
mesh.

2) CheckpointRead.png -- screenshot showing the output when reading the mesh

You can see exactly what I wrote in my earlier email, albeit with different
numbers this time.

3) Checkpoint.cxx  - a quick code. You have to use #if  0 segment to read
lshaped.xda, refine it, and save as Checkpoint format. Then change to #if 1
to read the "cp" mesh. I am assuming, AMR mesh will work, if this works for
read/write.

Many thanks for your help.

Regards,

Jahrul
