Hi All,
I have encountered problem with VTK export.
In getfem_export.h the type of exported data
is set to "float" (e.g. line 275).
Apparently that causes problems when the data
is saved with with more than 6 digits after
the decimal dot (this is just guess - I went to
this conclusion by manually truncating the digits)
Well, the fix is simple -- declare data type as double.
Now there is a question -- should we just change
"float" to "double" in vtk_export::write_dataset_
or shall we go for more sophisticated solution
of checking what is the actual type of elements of
written vector and then adjust the VTK data type ?
The fist solution is trivial the second might be a bit complex.
There is also another solution to add new property
to vtk_export to explicitly choose the VTK data type.
What is your opinion on this?
In the attachment there is the VTK file exported form GetFEM
that causes the problems. I am using ParaView 3.6.2.
and the SVN getfem version.
Regards,
Roman
