Yes, we use the VTKIO class to output the solution. We also need to output some nodal and elemental data, for which I serialize the mesh. It this possible through the VTKIO class, by creating additional variables in the system? Thanks, Harshad On Sat, Apr 18, 2015 at 1:30 PM, Derek Gaston wrote:

Why do you need to serialize the mesh? If you're writing out any of the serial formats (Exodus, VTK, Tecplot, etc.) then the mesh is serialized internally... you don't need to do it yourself. Derek On Sat, Apr 18, 2015 at 12:03 PM Harshad Sahasrabudhe wrote: > Hi Roy, > > Sorry I forgot to pos

Hi Roy, Sorry I forgot to post updates here. I ran the code in debug mode found that there is no problem with MeshSerializer. The root process was running a different collective function than other processes, which was the cause of the crash. I'll remind myself to run in debug mode before posting

[Libmesh-users] MeshSerializer gets stuck on root processor

Hi, I'm using MeshSerializer to serialize a mesh before output. The output files turn out to be fine. When I try to destroy the MeshSerializer, it gets stuck in the destructor on root process, while the code continues executing on other processes. Here is the back trace on root process: #6 0x00
