[Libmesh-users] output results of very huge mesh

[Bin L. <ken...@ho...>]

Hi,
I have written a mpi finite element program to solve a very large 3D problem, around 50 millions nodes. I have been able to split the mesh and read these decomposed mesh from each processors. However, I have a big problem to output the results for visualization.

>From my understanding, I should Serialize the mesh temporarily and output the mesh and solutions together. However, this serialization of mesh is very inefficient on one processor and takes a huge amount of memory and time to generate it.

Is there any way to write out the mesh and solutions together from each processor in parallel? It is not a problem for me to post-process them, as long as they are mesh and solution are exported.

Thanks
Ken
