使用MPI用并行C ++编写VTK

Question

I am new to C++ and I've just started to write a CFD (Computational Fluid Dynamics) code in parallel hybrid mode ( MPI + CUDA ). I would like to know if you have any references on how to write parallel VTK files using MPI ?

Any suggestions will be much appreciated.

Answer 1

I think this is maybe the simplest way you can do it:

1. Each process write its own .vts file (for unstructured grid it is .vtu).
2. Master process writes a .pvts file which contains information of the whole domain.
3. Open the .pvts file in ParaView or other softwares.
