[petsc-users] petsc binary vtk viewer

[Dharmendar Reddy]

Hello,
         I am seeing nan's at boundary locations for a plot over line data
on a 2D mesh. There are no nan's in the data obtained from solver.

For example, When i click plot over line along y-axis in paraview, it
selects the y-coordiantes to be from

-21.141444145 to 26.426805182  , The boundary Node at the positive end is
showing a nan.   If i change the end node to 26.426804  the nan goes away
and i get the expected value (which is zero, as per imposed boundary
condition).

I have not seen this before with the ascii vtk writer in my fortran code.

I am wondering if there is something i should be aware of petsc binary vtk
viewer.  I run the code on a 64 bit linux cluster. I am visualizing the vtk
file on a 32 bit paraview 3.10.1 on windows xp.



Thanks
Reddy
