I have tried to open the file in paraview but it cannot be identified. I then tried searching for it in the file finder but cannot find it.

So far so good. However, I need help on visualization of results in paraview. I have it installed and running but I don't know on how to visualize .pvd files using paraview.

Have you tried opening the .pvd file with paraview (and hitting the "Apply" button)?

Cheers,

Lawrence

I am actually trying to visualize the output in the tutorials. We already have for example: File(“poisson_mixed.pvd”) << u I have done: output = File(“poisson_mixed.pvd”) output << u del output And after that, I cannot locate the file poisson_mixed.pvd I might have erred somewhere.

What error did paraview give?

If you still have the python session that you used to create the pvd file open, you will need to close the pvd file in that before it appears in a useable form on disk:

So if you do something like:

output = File("output.pvd")

output << my_function

you need to do

del output

before the output.pvd is useable. This happens automatically when python exists.

This file is created in the directory you started the python process in. You can find that from within the python process with:

import os

print os.path.abspath(os.path.curdir)

The visual output of the helmholtz, burgers and mixed poisson in the tutorials are rectangular surfaces. This is when I open their respective .vtu files. What could be the problem?
