I called VTKIO(mesh).write_equation_systems (file_name.str(),
equation_systems) in a libmesh example code to dump an adaptive mesh with
solutions to VTK files. I ran three time steps and dumped the mesh every
time step. I got those files
out.001.pvtu
out.002.pvtu
out.003.pvtu
out_0.vtu
I am not sure when out_0.vtu was generated since I did not have such file
name. I found out.001.pvtu~out.003.pvtu had the SAME content like this:
<?xml version="1.0"?>
<VTKFile type="PUnstructuredGrid" version="0.1" byte_order="LittleEndian"
header_type="UInt32" compressor="vtkZLibDataCompressor">
<PUnstructuredGrid GhostLevel="1">
<PPointData>
<PDataArray type="Float64" Name="u"/>
</PPointData>
<PCellData>
<PDataArray type="Int32" Name="libmesh_elem_id"/>
<PDataArray type="Int32" Name="subdomain_id"/>
<PDataArray type="Int32" Name="processor_id"/>
</PCellData>
<PPoints>
<PDataArray type="Float64" Name="Points" NumberOfComponents="3"/>
</PPoints>
<Piece Source="out_0.vtu"/>
</PUnstructuredGrid>
</VTKFile>
I also found out_0.vtu only contained the mesh of the last time step. So,
how can I get the mesh every time step so that I can see how the mesh is
adaptively refined in ParaView?
Thank you!
