So are you saying that VTK 1.7 is (was) broken?

Hi @PetrKryslUCSD!

the package update ↑ WriteVTK v1.6.0 ⇒ v1.7.1 breaks some ot the tests in our project.

See the following issue for further details: #286

We did not dig deep yet into the cause of the broken test, but accordingly to the error backtrace reported in #286, we suspect that the changes in v.1.7.0 introduced in MeshCell may well behind the broken test (see the following comment: #286 (comment) for more details).

Are u experiencing issues with VTK 1.7 as well?

[amartinhuertas]

I think I could fix the broken tests in our particular case (comprehensive test suite still underway).

See ccd7565 for more details.

No, I am on
[64499a7a] WriteVTK v1.7.1
and I have seen no errors.

Hi, I just noticed this issue. I apologise for the breaking changes in WriteVTK, and I'm glad to see that you figured out the solution in #324.

To clarify, the MeshCell type in WriteVTK was modified in v1.7 to support the definition of polygonal meshes, which are a specific type of unstructured mesh. As I mentioned in a related issue, I didn't expect this change to break other projects such as this one.
